Re: [Freeswitch-users] SIP-Client / IOS / PJSIP / Error when CANCEL

7 Sep 2017

      Hello Thorsten

this is often caused by changed Contact: header in your SIP dialog. In
your case the 2 Invites have:
Contact: <sip:102@77.119.248.251>
Contact: <sip:102@192.168.178.110:5060;ob>

So this will not work.

Best regards from Germany

Hi,
currently we are developing a SIP-Client for iOS (using PJSIP/PJSUA with
the current version). We use Freeswitch 1.6.18 (64 bit) on a bare metal
server. Windows-Clients (such as Blink or Zoiper) work fine. And our
iOS-App works fine also. BUT when we initialze an outgoing call, wait
for ringing on the other hand and hangup up when it's ringing, we face
an error. Freeswitch gives us "481 Call/Transaction Does Not Exist".
I attached the corresponding SIP-Trace and you can see the error at the
last block.
The interesting thing: If we activate PJSIP with TCP and(!) UDP we face
the error. BUT when we use only UDP it works fine.
Is it a bug within PJSIP? Or anyone see an hint wihtin the SIP-Trace?
Thanks in advance!
