The only real solution to guarantee call control is to use a B2BUA as ser is 100% unaware of call status. Ser only maintains transaction state, not call state.

If your SIP UAs support the Session-Expires header then they will automatically send re-INIVITES which will disconnect the call and send a BYE message to SER in the event of a failure.

Hi all,

If my UAs doesn't have session-timer.

UA_a -------- SER ---------- PSTN ---------- UA_b

If the UA_a have a network crash, My PSTN gateway continue to bill my customer UA_a until UA_b have hanging up.

If I am right, I have to use a B2BUA to control the integrity of the call. I have TEST B2BUA of Vovida, but it doesn't very nice!

Thanks in advance for a good solution, HELP HELP HELP :0(

Excuse me for my english !

Best Regards,

Nicolas RUIZ France, Paris

Hi Paul,

I would actually not tend to say "the only solution" -- for PSTN accounting accuracy, which mostly matters, use of gateways with session-timer work well. Other cases to cut a call do not appear compelling to me -- in the end, phones will detect the conditions and hang up.

B2BUAs have also side-effect, at least weaker scalability.

OK, I understand !

I have to implement ST on my GATEWAY CISCO AS5300, that's right?

Thanks a lot for your advises!

The *gateway* must implement the ST. The UAC does not have to.

Ok, I have set the minimun ST interval on the Cisco GW5300 to 60s. But If my UA don't support "Session-Expires header", if I have a crash, it's the same problem, the call is not cut !

I think I need really a B2BUA solution, that's right?

Does Asterisk can be a B2BUA for billing ?

Thanks all for your help

Ragards,

Nicolas,

AFAIK, it is not mandatory for the GW itself to implement ST. You can have another SIP entities to do it.

Of course, a GW that support ST is an undeniable advantage; and most of CISCO GW support this - you just have to enable it. But you need to take care in your SER config file to process correctly the re-INVITEs generated by the GW. Also, since many UAC implementations does not add the "Session-Expires" header, you will need to take care of this in your SER script.

Best regards, Marian

OK, I have read a topic of the mailing list and I have seen that SER can modify Session Header.

Where on SER.cfg, I have to set this function ? for all requests ???

########################################################## if (status =~ "2[0-9][0-9]") { remove_hf("Session-Expires"); append_hf("Session-Expires: 120;refresher=UAC\r\n"); }; ##########################################################

And on the CISCO GW5300 I have just set this option, is it good ?

voice service voip

sip min-se 60

Thanks a lot ! :0)

You have to configure SER to insert ST. Jan posted some config samples recently on the mailing list, look for it.

I don't think so.
