Re: [OpenSIPStack] OpenSBC SIP Trunking - Null Sessionin CallSessionManager.cxx

[Gaurav K. <gkh...@is...>]

Hi Joegen,

We were able to get trunking working for inbound calls with OpenSBC. For the
outbound trunking issue, you mentioned:-

" I guessing OpenSBC was not able to identify the call as a trunk call 
properly.   You are correct that the trunk should have handled the 
authentication instead of relaying the 407.  If you are using the Main trunk
to route your calls to the SIP Trunk, you may try to use "sip-trunk"
parameter in our b2bua route
Example:  [sip:1212*] sip:mytrunkprovider.com;sip-trunk=true"

I subsequently tried that and found that sbc crashes in
SBCSIPTrunkReg::GetEgressAuthInfo function at the start of For loop.

*Configuration*

OpenSBC   		192.168.96.123
Xlite    		192.168.96.36
Public LAN IP	59.95.152.178
voipvoip.com 	69.90.209.57

*B2BAUA Route*

[sip:*@192.168.96.123] sip:sip3.voipvoip.com:5060;sip-trunk=true

*Trunking*

<root>
<siptrunk trunk-name="SIP"
  route-set="sip3.voipvoip.com"
  sip-domain="59.95.152.178"
  expires="3600">

<trunk-accounts>
  <account user-name="phonenumber"
   auth-user-name="phonenumber"
   auth-password="password"
   inbound-route="sip:102@192.168.96.123:5060"
   expires="3600"/> 
  </trunk-accounts>
  </siptrunk>
</root>

The pcap file is attached for your reference.

As always, thanks in advance for your help!
