SIP session timer - RFC4028

1. Brekeke Product Name and version:
BSS, 2.4.8.6, 3.2.3.6

2. Java version:
1.6.0_25, 1.6.0_45

3. OS type and the version:
linux centos 5.5

4. UA (phone), gateway or other hardware/software involved:
doesn't matter

5. Your problem:
I wanted to know if BSS is able to run SIP session timers to update/refresh the session / check if it is still up (RFC 4028). RTP timer is not what i am looking for because RTP is flowing around the BSS.
The problem i am encountering is that from time to time some of the calls are hanging in Closing, Accepted or Initialized status. Thats why i want to set re-INVITE or UPDATE periodically to verify the session and narrow down calls affected.

Thanks.

Can session timer be enabled at clients side?
Brekeke PBX has session timer feature.

Have you tried to set [Ringing Timeout] and [Talking Timeout] in the [Configuration]->[SIP]?

The SIP server tracks Session-Timer's re-INVITE and UPDATE, and closes a session automatically after the timeout period if there are no packet activities.

Hi Tata,

Yes i am familiar with these timers.
I am rather looking for a possibility to setup a kind of update timer (120secs for instance)
After its expiration BSS should send reInvite or Update and wait for response to decide if session is still active or there was a kind of problem and the session is no more active.

Do we have this type of timer available in BSS?

Thanks.

We have Brekeke PBX which supports RFC4028 and meets the requirement.

For Brekeke SIP Server, we have a plan to implement such a function in a further version.

Thanks Mike for an update.
Will it be next release or is it in your roadmap scheduled for further rel?

The reason i would like to cover this case is that we are having "hanged calls", even net.sip.timeout.talking is not limiting them.
Disconnecting them manualy is affecting 481 Call/Transaction does not exist message received from call originator.
Unfortunately we are not using RTP Proxy to benefit from RTP Session timeout.

Thanks.

Hi mbylica,
Hopefully, it will be in the version 3.3.

If there is an urgent demand, let you try Brekeke PBX.

same problem that mbilica.
Expect for this update.
thanks

Version 3.3.x.x is already there.
Could you please tell me how to turn it on?

Hi mbylica,

Brekeke SIP Server ver3.3 doesn't have the feature yet.
It accepts session timer's headers but doesn't close a session by itself.

I discuss it with the developer team and hope they raise the priority.

Thank you,
