[Serusers] end the session if no media

What I'm saying is that you probably want to differ between a long call that after 59 minutes is put on hold and a terminated call where the BYE never came. Both will show no RTP (dependent on UA). Your session controller may be able to tell you if the call is on hold.
With regards to No transaction exist: Do you send the BYE directly to the UA and the UA replies with this? If so, I wouldn't worry too much, it just means that you were right in terminating the call because the UA does know of any call. I'm a bit uncertaint about the error though, looks like you may get it from ser (if you send through ser), then the BYE never reaches the UA. (I would expect the UA to respond Call leg doesn't exist). How do you send the BYE that gives this error and to where?

Yes, I know about it. I can see the active sessions from the session.py. But do not know how to end the seesion, if there is no rtp session and the bye has not come. My session con troller does not check the rtp session because the media is proxied at SER. As I know, may be I am wrong, the ser is managing the media proxy. Ser says to media proxy to start when a call is proxied, and end when the call is finished.
Do you suggest a SBC that can do this function..?
Thanks,
Best Regards,

session.py will show if the session is active. Also when a call is put on hold, there will be no rtp stream. I don't know if your SBC handles that.
Or is your question something else?

Hi Teigre,
Thanks for your reply and kind suggestions. In fact, I am using a session controller for sip calls. And it alerts me via email when a sessiıon is reached for about 60 minutes. At that time,
I check it manually and kil the session if the session is abondened. By sending BYE messages to both legs. From the PSTN side I get the reply what I assume ( 200 OK ) but from the sip side I get No transaction exist.
Because the session was ended before and session controller couldn’t get the BYE message for some reasons. ( Network failure or something else ).
What I am looking for that, from the media proxy, I see the active rtp session when I use media proxy for the calls. And I assume that, when the call has finished and couldn’t send or get BYE message, there will be no rtp stream going on. May be I am wrong for this. If rtp session is still open when the a side hunp up and couldn’t send bye , there is nothing to do except killing the session with sending bye messages to both sides, because there is no way to understand the call is active or not.
Best Regards,
Hakan

Hakan and Ritesh,
It seems to me that you are both asking about the same thing. This topic has been discussed many times on serusers. Search google (site:mail.iptel.org) for "BYE stateful sipsak", I'm pretty sure you will get some info.
Also, this FAQ could help:

Hi,
I wonder, is there any way, to end the session when the media has ended. Sometimes, we have problem at BYE message. For some reasons, the bye is not coming and may be it is coming wrong.
At that time, the media is ended but the call is seen as active.
I am using ser and using media proxy.
Any suggestion for this issue ?
