Subscription-State: terminated;reason=terminated?
by Min Wang 27 Jun '12

27 Jun '12

HI when I removed 102 from 101's contact list (using jitsi nightly 1.1 build), kamailio 3.3 send out NOTIFY to 102 like this: NOTIFY sip:102@192.168.122.147:5060;transport=udp;registering_acc=192_168_122_32 SIP/2.0. Via: SIP/2.0/UDP 192.168.122.32;branch=z9hG4bK1bfb.afbf0a85.0. To: sip:102@192.168.122.32;tag=f6a40771. From: sip:101@192.168.122.32;tag=a6a1c5f60faecf035a1ae5b6e96e979a-5724. CSeq: 4 NOTIFY. Call-ID: c7c52dd058268596ec84dd3c645a2f17(a)0.0.0.0. Content-Length: 0. User-Agent: kamailio (3.3.0-rc0 (x86_64/linux)). Max-Forwards: 70. Event: presence. Contact: <sip:192.168.122.32:5060;transport=udp>. Subscription-State: terminated;reason=terminated. <----------------- Note the reason code is:terminated. From rfc3265, The defined reason codes are: deactivated/ probation/rejected/ timeout/giveup/noresource What is the reason to send: reason=terminated instead one of the well-defined reason codes? There was a discussion regarding at: http://sip-router.org/tracker/index.php?do=details&task_id=133 <http://sip-router.org/tracker/index.php?do=details&task_id=133> but I did not see the explaination of reason=terminated. Thanks min

default kamailio configuration
by Vitaliy Aleksandrov 27 Jun '12

27 Jun '12

Hi All, After reading default kamailio configuration i can't understand why does kamailio remove preloaded route headers from the incoming initial INVITE before calling record_route(). remove_hf("Route"); if (is_method("INVITE|SUBSCRIBE")) record_route(); What will happen if an INVITE comes from another SIP proxy which wants to stay in the middle of the dialogue ? For example, during Re-INVITE UA from our local site will construct in-dialog INVITE with R-URI taken from the remote contact and send it to our local proxy according to RR. Local proxy will process it in route[WITHNDLG] where loose_route() function will remove top most RR header because it points to us and since there is no more RR records forward the request to a destination from the R-URI. As i understand in that case remote proxy will not receive any in-dialog requests from us.

kamailio.org server maintenance - estimated 1 hour downtime, 26/27 June
by Daniel-Constantin Mierla 27 Jun '12

27 Jun '12

Hello, during the night of 26/27th of June, Central European Standard Time (GMT+1, with daylight saving time on), the server hosting kamailio.org and lists.sip-router.org will be down for approx 1 hour. This is a planned maintenance work to upgrade the server to a new infrastructure. Hopefully everything goes smooth and gets back online quickly, the work should start about 2:00am on the 27th of June, but don't get nervous if takes longer or happens at different time. Among the most important affected services: - the mailing lists (all mailed in this message) - main website and kamailio's wiki systems - download folders - documentations (for modules and other html tutorials) The sip-router.org server will NOT be affected, so next services will be available: - sip-router.org web site and its wiki - GIT repository - issue tracker system If things are not going as expected, tomorrow we will post news about on this server, at http://sip-router.org This is a good opportunity to thank again to voztele.com for sponsoring the server and taking care of the maintenance work.

The easiest will be that the user agent will publish in behalf of the public id. But ultimately, you can replace the values in headers and xml body (see textops/xmlops functions), then do presence handling, after applying the changes to the message (see textopsx module).

Kamailio : Listening on multiple ports behind NAT
by Reda Aouad 26 Jun '12

26 Jun '12

Hello, I am trying to implement the following configuration : - Kamailio as a SIP proxy/registrar behind a one-to-one NAT (port number is not modified) listening on ports 5060 and 53 (and more ports in the future) - aliases correctly configured : alias= udp: public_ip:53 alias= udp: public_ip:5060 alias= udp: hostname:53 alias= udp: hostname:5060 - listen directive correctly on private ip address and both ports : listen=udp:private_ip:53 listen=udp:private_ip:5060 - advertised_address=public_ip - record_route_preset("public_ip") is used to announce the public IP address in the RR header - user A : registered on port 5060 - user B : registered on port 53 Suppose user A tries to call user B. The Record-Route header in the INVITE forwarded from Kamailio to user B should contain the port number on which user B is connected (53), to force user B to send future requests to that port number. But I have no method to know which port user B is connected to, and that problem is aggravated when user B has multiple registrations on different port numbers and parralel forking is done. Declaring advertised_port doesn't solve the problem. I cannot force port number 53 in record_route_preset("public_ip:53") since it wouldn't work when user B calls user A. Using the record_route( ) function, Kamailio doesn't use the advertised_address to construct the RR header. Another problem is that the record_route_preset function clears the DID cookie set by the dialog module, which makes Kamailio fallback to SIP elements to match the request to an existing dialog, thus dialog matching becomes slower, and performance is an issue for me. Any suggestions? I know that one solution would be to run Kamailio with a public IP address and no NAT, but unfortunately it's not possible. I suggest that the function record_route( ) takes a public IP address as a parameter, still doing what it does (correct record routing and cookie addition did=xxx and loose route lr=on), but only replacing the private IP address on which Kamailio listens with a public IP address. Or that the record_route( ) function uses the advertised_address to construct the RR header. Thank you RA

Fwd: Can Kamailio be used to redirect media between a client that switches from wifi to 3g/gsm

Forgot to post the response to the list as well.
