Hello Daniel,
thank you for your reply.
I changed the line mentioned to t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "$su", "192.168.1.156","Call-ID: $hdr(Call-ID)\r\nSubscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-%7Bmac%7D http://server.conf/settings-%7Bmac%7D");
the result is: 3) Call-ID is fine now ; Problem solved :-)
1) The Via IP is now changed to the IP and port of the server, but not to the IP of the phone.
2) The sending interface / IP is not correct: It now sends _only_ from the wrong IP !! As a result, it repeats sending the NOTIFY-message over and over again since the message does not get to the phone ... Please see the starting of the SIP-traffic below

(If I change the IP-parameter to "172.23.56.1" the resulting sending IP is unchanged!)

Hallo,
several telephones send a SIP-multicast SUBSCRIBE message to address 224.0.1.75 if they have no settings-URL configured and receive none over DHCP.
So I configure my kamailio server, to respond to that multicast-request. But: Although mine is working, I do feel it could be improved, since the NOTIFY packet send out is not quite as it should be …
Here is what I did (the 172.23.56.1 is my voip-vlan-address)
listen=udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060
….
if ($Ri == "224.0.1.75"){ if(is_method("SUBSCRIBE")){ xlog("L_INFO", "Received pnp-event from IP $si from User-Agent $hdr(User-Agent) und User $fU\r\n" ); sl_send_reply("200", "OK"); t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "", "","Subscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-%7Bmac%7D http://server.conf/settings-%7Bmac%7D"); }else { xlog("L_INFO", "Drop message $rm from pnp-Interface \r\n" ); } exit; }
And here are the SIP-packets I see on my server (192.168.1.156) coming from my snom-phone (192.168.1.152). My problems with the NOTIFY -packets are:
- How do I set the Via parameters to be the same as in the OK-reply?
Try to set the next hop address to "$su" and combined with 2) maybe it results in what you want to get.
- How do I send out the NOTIFY only via the 192.168.1.156 network interface?
Set the local socket parameter from where to send the NOTIFY.
- May I send out the NOTIFY with the Call-ID from the SUBSCRIBE message? How?
Provide the Call-Id haeder as part of the headers parameter:

Any help is highly appreciated Jan-Hendrik

Hello Daniel,
thank you for your reply.
I changed the line mentioned to t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "$su", "192.168.1.156","Call-ID: $hdr(Call-ID)\r\nSubscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-%7Bmac%7D http://server.conf/settings-%7Bmac%7D");
the result is: 3) Call-ID is fine now ; Problem solved :-)
OK.
- The Via IP is now changed to the IP and port of the server, but not
to the IP of the phone.
Actually that is the correct value, Via is the address of the entity sending out the request. It is used to route the replies, so Via in Notify has to be the address of the kamailio server so the reply to it is sent by the phone back to Kamailio.
- The sending interface / IP is not correct: It now sends _only_
from the wrong IP !!
Can you try with full specs for socket, like "upd:IP:port"?
Cheers, Daniel
As a result, it repeats sending the NOTIFY-message over and over again since the message does not get to the phone ... Please see the starting of the SIP-traffic below

Hallo,
several telephones send a SIP-multicast SUBSCRIBE message to address 224.0.1.75 if they have no settings-URL configured and receive none over DHCP.
So I configure my kamailio server, to respond to that multicast-request. But: Although mine is working, I do feel it could be improved, since the NOTIFY packet send out is not quite as it should be …
Here is what I did (the 172.23.56.1 is my voip-vlan-address)
listen=udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060
….
if ($Ri == "224.0.1.75"){ if(is_method("SUBSCRIBE")){ xlog("L_INFO", "Received pnp-event from IP $si from User-Agent $hdr(User-Agent) und User $fU\r\n" ); sl_send_reply("200", "OK"); t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "", "","Subscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-%7Bmac%7D http://server.conf/settings-%7Bmac%7D"); }else { xlog("L_INFO", "Drop message $rm from pnp-Interface \r\n" ); } exit; }
And here are the SIP-packets I see on my server (192.168.1.156) coming from my snom-phone (192.168.1.152). My problems with the NOTIFY -packets are:
- How do I set the Via parameters to be the same as in the OK-reply?
Try to set the next hop address to "$su" and combined with 2) maybe it results in what you want to get.
- How do I send out the NOTIFY only via the 192.168.1.156 network
interface?
Set the local socket parameter from where to send the NOTIFY.
- May I send out the NOTIFY with the Call-ID from the SUBSCRIBE
message? How?
Provide the Call-Id haeder as part of the headers parameter:

But what did help in this particular case is to change the order of the listen Interfaces:
From:
listen=udp:172.23.56.1:5060 udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=udp:192.168.1.156:5060 udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060 udp:224.0.1.75:5060
To:
listen=udp:192.168.1.156:5060 udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=udp:172.23.56.1:5060 udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060 udp:224.0.1.75:5060
Although this workaround works here, it is difficult in cases when sending events to different networks. (for example check-sync events).

Hello Daniel,
thank you for your reply.
I changed the line mentioned to t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "$su", "192.168.1.156","Call-ID: $hdr(Call-ID)\r\nSubscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-%7Bmac%7D http://server.conf/settings-%7Bmac%7D");
the result is: 3) Call-ID is fine now ; Problem solved :-)
OK.
- The Via IP is now changed to the IP and port of the server, but not to the IP of the phone.
Actually that is the correct value, Via is the address of the entity sending out the request. It is used to route the replies, so Via in Notify has to be the address of the kamailio server so the reply to it is sent by the phone back to Kamailio.
- The sending interface / IP is not correct: It now sends _only_ from the wrong IP !!
Can you try with full specs for socket, like "upd:IP:port"?
Cheers, Daniel
As a result, it repeats sending the NOTIFY-message over and over again since the message does not get to the phone ... Please see the starting of the SIP-traffic below

So I configure my kamailio server, to respond to that multicast-request. But: Although mine is working, I do feel it could be improved, since the NOTIFY packet send out is not quite as it should be …
Here is what I did (the 172.23.56.1 is my voip-vlan-address)
listen=udp:172.23.56.1:5060 udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=udp:192.168.1.156:5060 udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060 udp:224.0.1.75:5060
….
if ($Ri == "224.0.1.75"){ if(is_method("SUBSCRIBE")){ xlog("L_INFO", "Received pnp-event from IP $si from User-Agent $hdr(User-Agent) und User $fU\r\n" ); sl_send_reply("200", "OK"); t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "", "","Subscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-%7Bmac%7D http://server.conf/settings-%7Bmac%7D"); }else { xlog("L_INFO", "Drop message $rm from pnp-Interface \r\n" ); } exit; }
And here are the SIP-packets I see on my server (192.168.1.156) coming from my snom-phone (192.168.1.152). My problems with the NOTIFY -packets are:
- How do I set the Via parameters to be the same as in the OK-reply?
Try to set the next hop address to "$su" and combined with 2) maybe it results in what you want to get.
- How do I send out the NOTIFY only via the 192.168.1.156 network interface?
Set the local socket parameter from where to send the NOTIFY.
- May I send out the NOTIFY with the Call-ID from the SUBSCRIBE message? How?
Provide the Call-Id haeder as part of the headers parameter:

Any help is highly appreciated Jan-Hendrik

So here is my insight to the problem:
Because the first listening interface is advertising the 192.168.1 interface, this one is used. If I change the order to
listen=udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
I can use both sockets as expected.
Ergo: Always use the primary / actual interface before the ones which only advertised it!

….
But what did help in this particular case is to change the order of the listen Interfaces:
From:
listen=udp:172.23.56.1:5060 udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=udp:192.168.1.156:5060 udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060 udp:224.0.1.75:5060
To:
listen=udp:192.168.1.156:5060 udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=udp:172.23.56.1:5060 udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060 udp:224.0.1.75:5060
Although this workaround works here, it is difficult in cases when sending events to different networks. (for example check-sync events).

Hello Daniel,
thank you for your reply.
I changed the line mentioned to t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "$su", "192.168.1.156","Call-ID: $hdr(Call-ID)\r\nSubscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-%7Bmac%7D http://server.conf/settings-%7Bmac%7D");
the result is: 3) Call-ID is fine now ; Problem solved :-)
OK.
- The Via IP is now changed to the IP and port of the server, but not to the IP of the phone.
Actually that is the correct value, Via is the address of the entity sending out the request. It is used to route the replies, so Via in Notify has to be the address of the kamailio server so the reply to it is sent by the phone back to Kamailio.
- The sending interface / IP is not correct: It now sends _only_ from the wrong IP !!
Can you try with full specs for socket, like "upd:IP:port"?
Cheers, Daniel
As a result, it repeats sending the NOTIFY-message over and over again since the message does not get to the phone ... Please see the starting of the SIP-traffic below

Hello,

Hallo,
several telephones send a SIP-multicast SUBSCRIBE message to address 224.0.1.75 if they have no settings-URL configured and receive none over DHCP.
So I configure my kamailio server, to respond to that multicast-request. But: Although mine is working, I do feel it could be improved, since the NOTIFY packet send out is not quite as it should be …
Here is what I did (the 172.23.56.1 is my voip-vlan-address)
listen=udp:172.23.56.1:5060 udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=udp:192.168.1.156:5060 udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060 udp:224.0.1.75:5060
….
if ($Ri == "224.0.1.75"){ if(is_method("SUBSCRIBE")){ xlog("L_INFO", "Received pnp-event from IP $si from User-Agent $hdr(User-Agent) und User $fU\r\n" ); sl_send_reply("200", "OK"); t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "", "","Subscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-%7Bmac%7D http://server.conf/settings-%7Bmac%7D"); }else { xlog("L_INFO", "Drop message $rm from pnp-Interface \r\n" ); } exit; }
And here are the SIP-packets I see on my server (192.168.1.156) coming from my snom-phone (192.168.1.152). My problems with the NOTIFY -packets are:
- How do I set the Via parameters to be the same as in the OK-reply?
Try to set the next hop address to "$su" and combined with 2) maybe it results in what you want to get.
- How do I send out the NOTIFY only via the 192.168.1.156 network interface?
Set the local socket parameter from where to send the NOTIFY.
- May I send out the NOTIFY with the Call-ID from the SUBSCRIBE message? How?
Provide the Call-Id haeder as part of the headers parameter:

Indeed, the search of sockets is done by local address as well as advertised address. I want to add a new attribute to listen directives to give them a name (unique id), to be easier to specify which one should be used -- in my todo list for quite some time, but I didn't get the time for it.
Cheers, Daniel

So here is my insight to the problem:
Because the first listening interface is advertising the 192.168.1 interface, this one is used. If I change the order to
listen=udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
I can use both sockets as expected.
Ergo: Always use the primary / actual interface before the ones which only advertised it!

But what did help in this particular case is to change the order of the listen Interfaces:
From:
listen=udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060
To:
listen=udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060
Although this workaround works here, it is difficult in cases when sending events to different networks. (for example check-sync events).

Hello Daniel,
thank you for your reply.
I changed the line mentioned to t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "$su", "192.168.1.156","Call-ID: $hdr(Call-ID)\r\nSubscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-%7Bmac%7D http://server.conf/settings-%7Bmac%7D");
the result is: 3) Call-ID is fine now ; Problem solved :-)
OK.
- The Via IP is now changed to the IP and port of the server, but
not to the IP of the phone.
Actually that is the correct value, Via is the address of the entity sending out the request. It is used to route the replies, so Via in Notify has to be the address of the kamailio server so the reply to it is sent by the phone back to Kamailio.
- The sending interface / IP is not correct: It now sends _only_
from the wrong IP !!
Can you try with full specs for socket, like "upd:IP:port"?
Cheers, Daniel
As a result, it repeats sending the NOTIFY-message over and over again since the message does not get to the phone ... Please see the starting of the SIP-traffic below

(If I change the IP-parameter to "172.23.56.1" the resulting sending IP is unchanged!)

Hello,

Hallo,
several telephones send a SIP-multicast SUBSCRIBE message to address 224.0.1.75 if they have no settings-URL configured and receive none over DHCP.
So I configure my kamailio server, to respond to that multicast-request. But: Although mine is working, I do feel it could be improved, since the NOTIFY packet send out is not quite as it should be …
Here is what I did (the 172.23.56.1 is my voip-vlan-address)
listen=udp:172.23.56.1:5060 advertise 192.168.1.156:5060 listen=udp:192.168.1.156:5060 advertise 192.168.1.156:5060 listen=tcp:127.0.0.1:5060
mcast="eth0" listen=udp:224.0.1.75:5060
….
if ($Ri == "224.0.1.75"){ if(is_method("SUBSCRIBE")){ xlog("L_INFO", "Received pnp-event from IP $si from User-Agent $hdr(User-Agent) und User $fU\r\n" ); sl_send_reply("200", "OK"); t_uac_send("NOTIFY", "$(ct{s.substr,1,0}{s.striptail,1})", "", "","Subscription-State: terminated;reason=timeout\r\nEvent: $hdr(Event)\r\nContent-Type: application/url\r\nFrom: $fU\r\nTo: $hdr(From)", "http://server.conf/settings-%7Bmac%7D http://server.conf/settings-%7Bmac%7D"); }else { xlog("L_INFO", "Drop message $rm from pnp-Interface \r\n" ); } exit; }
And here are the SIP-packets I see on my server (192.168.1.156) coming from my snom-phone (192.168.1.152). My problems with the NOTIFY -packets are:
- How do I set the Via parameters to be the same as in the OK-reply?
Try to set the next hop address to "$su" and combined with 2) maybe it results in what you want to get.
- How do I send out the NOTIFY only via the 192.168.1.156
network interface?
Set the local socket parameter from where to send the NOTIFY.
- May I send out the NOTIFY with the Call-ID from the SUBSCRIBE
message? How?
Provide the Call-Id haeder as part of the headers parameter:
