38 seconds sounds pretty close to 30 seconds. Could those 38 seconds be a 30 seconds after the actual answer packet?

If so, you might want to look at ACK and OK packets not arriving correctly because of NAT, wrong IP selection in openser , etc...

A simple tshark might help you out to debug from a higher perspective : tshark -i eth0 -R sip 

good luck!

Greetings list,

I am experiencing a strange behavior with openser 1.3.2 running on ubuntu 10. I have a basic configuration (see bellow) and i am using Linphone for iPad as my client. I have 2 users registered and I am able to place calls no problem. The problem is that the calls (audio or A/V) drop after 38 seconds exactly, this behavior is pretty consistent, 38 seconds is all I can get. There is no firewall in front of the clients.

Here is my configuration, ip addresses changed to protect the innocent:

You can see the logs of the call here (the majority):

Am I missing something or is there anything that needs to be changed in the routing/configuration to achieve basic functionality?

Thank you in advance!
