[Serusers] When the UA crash (network or power) : the call continue!!!!

[Nicolas Ruiz]

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

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.
