NO JOY Audio drops after 30 mins of call duration

[markd89]

Hi All,

I have been using PIAF Purple 3.0.9 for a while with success. This is hosted under Centos and clients connect through Neorouter VPN.

Recently, I noticed calls dying after what seems like exactly 30 mins. Dying meaning that I don't hear anything and the other party stops hearing me, but the SIP client still thinks it is connected.

At first I thought this was a trunk issue, but then I had the same problem with an extension to extension call.

I know how to turn on logging, but before doing that, I thought I would ask if anyone has any obvious settings that I should be checking.

Thanks in advance for any suggestions..

Mark

This is typically a SIP session timer problem, but can be firewall. What kind of phones and what kind of firewall?

atsak, thanks for your reply.

On the server, the firewall is iptables.

The clients are Windows 7, running Personal Firewall (http://www.privacyware.com/personal_firewall.html).

We're running MicroSIP (http://www.microsip.org/)

Thanks,
Mark

I had a system with the same issue. In sip settings I added session-timers = refuse and the problem stopped. The phones were on the local network.

Thanks, that's super-helpful!

I added session-times=refuse in the PIAF UI under Tools, Asterisk SIP Settings, Other SIP Settings. Is that the right place or should I be making that change directly in a .conf? If directly in a .conf what file/folder should I be checking?

Thanks again!
Mark
