[Partysip-dev] Call setup problems

[Marian Durkovic]

Hi all,


   I'm trying to setup patrysip 0.5.6. as a proxy server for SIP calls.
However, I've run into the following problems:

1) when trying to make a call, the phone rings only for 30 seconds. After
this amount of time partysip sends CANCEL to the called party and 
408 Request Timeout to the calling party. It does not accept the Expires
header in INVITE message, which requests e.g. 180 seconds timeout.

2) partysip drops the ACK after 200 OK message in case the client sends it 
via partysip. Yes, there's the following comment in src/psp_core3.c:

 /* It can be a ACK for 200 ok, but those ACK SHOULD
 never go through this proxy! (and should be sent to the contact header */

But there are applications which do it this way - for example sip-h323
translators, which only talk to the nearest sip proxy and thus are sending
the ACKs after 200 OK to them as well. Also some UAs do it like this.
When partysip drops the ACK, the call could not be established.


      Thanks in advance for your help.
