[asterisk-users] Asterisk disconnecting SIP Calls after 15 Minutes

What is your provider seeing? Many providers send re-INVITEs at 15 minutes. Many firewalls have closed their port before this due to UDP timeouts. I have a whitepaper that I wrote on this subject; I will see if I can dig it up.

I did try the latest 1.8.2x release already without any improvement.
Currently running is a Asterisk PBX 1.8.10.1~dfsg-1ubuntu1 as the tcpdump says (little mistake to my last mail).
I also played around with "canreinvite". But regardless of the setting
(yes/no) I still get disconnects after 15 minutes. I just tried to accept session-timers, but this has no connection to this issue either.
So I turned on SIP debug for this host and analyszed it with wireshark.
The last packets show an INVITE from my provider, that is answered by my Asterisk with "200 OK, with session description". What follows is an ACK by the provider and immediately a BYE sent by the provider. So for me it looks like the provider is disconnecting the call.
I could not see any reason or hangup cause for this in the dump. Are there error messages for this that can be seen in the protocol?
The tcpdump (the last few packets) shows:
