Hi Daniel,

Thanks for the reply, here's my INVITE and BYE packet, I tcpdump-ed and and use wireshark to export as txt, so the format might be abit off.

1) Invite from OpenSER to Asterisk via port 5060, asterisk return a 200. And the call successfully established ------------------------------------------------------------------------ Record-Route: sip:%OpenSER_IP%;r2=on;lr;ftag=1247871f;nat=yes Record-Route: sip:%OpenSER_IP%:5061;transport=tls;r2=on;lr;ftag=1247871f;nat=yes Via: SIP/2.0/UDP %OpenSER_IP%;branch=z9hG4bKe42e.ff11ae32.0;i=52 Via: SIP/2.0/TLS %UAC_LAN_IP%:23323;received=%UAC_WAN_IP%;branch=z9hG4bK-d87543-2820ee009262b500-1--d87543-;rport=3135 Max-Forwards: 69 Contact: sip:davidloh@%UAC_WAN_IP%:3135;transport=TLS To: "001"sip:001@%SIP_Domain% From: "ser"sip:davidloh@%SIP_Domain%;tag=1247871f Call-ID: Zjc4OWJhZGNiMDUxNjQ5Y2I2ZDU3NTc4NGY2Y2RmOGQ.

2) Here's the BYE, from Asterisk to OpenSER. ------------------------------------------------------------------------ Via: SIP/2.0/UDP %Asterisk_IP%:5060;branch=z9hG4bK0ca1ab09;rport Route: sip:%OpenSER_IP%;r2=on;lr;ftag=1247871f;nat=yes,sip:%OpenSER_IP%:5061;transport=tls;r2=on;lr;ftag=1247871f;nat=yes From: "001"sip:001@%SIP_Domain%;tag=as0492a9d0 To: "ser"sip:davidloh@%SIP_Domain%;tag=1247871f Call-ID: Zjc4OWJhZGNiMDUxNjQ5Y2I2ZDU3NTc4NGY2Y2RmOGQ.

3) And then, OpenSER passing the BYE to UAC... ------------------------------------------------------------------------ Record-Route: sip:%OpenSER_IP%;lr;ftag=as0492a9d0 Via: SIP/2.0/UDP %OpenSER_IP%;branch=z9hG4bK5e.1195fd8.0 Via: SIP/2.0/UDP %Asterisk_IP%:5060;branch=z9hG4bK0ca1ab09;rport=5060 From: "001"sip:001@%SIP_Domain%;tag=as0492a9d0 To: "ser"sip:davidloh@%SIP_Domain%;tag=1247871f Call-ID: Zjc4OWJhZGNiMDUxNjQ5Y2I2ZDU3NTc4NGY2Y2RmOGQ.

I think the "protocol/port mismatch" happened right after (3) because from my ethereal trace, after short while (perhaps timeout), Asterisk will re-initiate a "BYE" and pass to OpenSER (packet #2), and OpenSER will forward it to UAC (packet #3), but somehow UAC doesn't response an "ACK" to OpenSER that why from my ethereal trace, packet #2 and #3 kept looping.

Any thoughts ?

Thanks in advance.

Hello,

can you paste the BYE here (you can catch it with ngrep if it is not coming via tls, e.g., from asterisk)? Also, the invite going to asterisk will be good.

Cheers, Daniel

Hi All,

Good day, I'm new to this mailing list :-)

I've setup an OpenSER server with TLS implementation, so far I tested everything works fine, but there's strange problem for "BYE" request, from the openser's log it always complaint: "Aug 19 22:58:40 ser /sbin/openser[16171]: WARNING:get_send_socket: protocol/port mismatch"

Here's my implementation: UA -> OpenSER -> Asterisk (as RTP) -> OpenSER -> UA On OpenSER I've two port opened which is Udp 5060 and TCP 5061 (TLS). My UA is Eyebeam v1.5 and the CA certificate (self-signed) already installed into IE "Trusted RootCA Certificates". So far I've tested p2p and pstn calls (and call to playback balance/asterisk), but the problem is unless UA disconnect the call (initiate BYE), otherwise if remote party (p2p/pstn/asterisk) initiate BYE request, my UA will forever stay connected until I disconnect the call manually.

So far I've identified the BYE request from remote party will go into Loose Route, and I've place a xlog to display the R-Uri.. here's the log from openser: (notes: if UA dial '001' will playback his/her balance from asterisk)

Below is my openser.cfg, loose route section

  ###############
   # Loose route #
   ###############

if(loose_route()) { if(has_totag() && (is_method("INVITE") || is_method("ACK"))) { if(nat_uac_test("19") || search("^Route:.*;nat=yes")) { fix_nated_contact(); } }

   xlog("L_INFO", "DBG: [$fu]($si) $rm [$tu] relayed LOOSE ROUTE");
   xlog("L_INFO", "DBG: ruri [$ru] relayed LOOSE ROUTE");

   exit;

}

Had anyone encountered the same problems before ? Do you mind to share your experience with me ? Your help are greatly appreciated, thanks in advance.

As you can see the last few BYE request wasn't able to deliver to UAC (or UAC failed to response), and it kept looping. For me the packets look fine, really no clue what's could go wrong here :(

Thanks, David Loh

Hello,

please send the request uri as well and the details about the IP communication (source/destination address, port).

use:

ngrep -qt -W byline port 5060

the replace the IPs with something suggestive to protect your privacy.

Hi Daniel,

Thanks for the reply, here's my INVITE and BYE packet, I tcpdump-ed and and use wireshark to export as txt, so the format might be abit off.

1. Invite from OpenSER to Asterisk via port 5060, asterisk return a

200. And the call successfully established

2. Here's the BYE, from Asterisk to OpenSER.

I think the "protocol/port mismatch" happened right after (3) because from my ethereal trace, after short while (perhaps timeout), Asterisk will re-initiate a "BYE" and pass to OpenSER (packet #2), and OpenSER will forward it to UAC (packet #3), but somehow UAC doesn't response an "ACK" to OpenSER that why from my ethereal trace, packet #2 and #3 kept looping.

Any thoughts ?

Thanks in advance.

Hello,

can you paste the BYE here (you can catch it with ngrep if it is not coming via tls, e.g., from asterisk)? Also, the invite going to asterisk will be good.

Cheers, Daniel

Hi All,

Good day, I'm new to this mailing list :-)

I've setup an OpenSER server with TLS implementation, so far I tested everything works fine, but there's strange problem for "BYE" request, from the openser's log it always complaint: "Aug 19 22:58:40 ser /sbin/openser[16171]: WARNING:get_send_socket: protocol/port mismatch"

Here's my implementation: UA -> OpenSER -> Asterisk (as RTP) -> OpenSER -> UA On OpenSER I've two port opened which is Udp 5060 and TCP 5061 (TLS). My UA is Eyebeam v1.5 and the CA certificate (self-signed) already installed into IE "Trusted RootCA Certificates". So far I've tested p2p and pstn calls (and call to playback balance/asterisk), but the problem is unless UA disconnect the call (initiate BYE), otherwise if remote party (p2p/pstn/asterisk) initiate BYE request, my UA will forever stay connected until I disconnect the call manually.

So far I've identified the BYE request from remote party will go into Loose Route, and I've place a xlog to display the R-Uri.. here's the log from openser: (notes: if UA dial '001' will playback his/her balance from asterisk)

Below is my openser.cfg, loose route section

  ###############
   # Loose route #
   ###############

if(loose_route()) { if(has_totag() && (is_method("INVITE") || is_method("ACK"))) { if(nat_uac_test("19") || search("^Route:.*;nat=yes")) { fix_nated_contact(); } }

   xlog("L_INFO", "DBG: [$fu]($si) $rm [$tu] relayed LOOSE

   exit;

}

Had anyone encountered the same problems before ? Do you mind to share your experience with me ? Your help are greatly appreciated, thanks in advance.
