[Serusers] Re: How Do I Enable Session Timers On PSTN->SIP Calls?

[Iqbal]

Hi

Okay so that I'm on the same page with this, doe sthis mean if my GW 
supports this...from what I read cisco seems to, that on a INVITE coming 
from a UA (even if its not cisco), I can set session-expires, and use 
the GW then to drop the session...if so when dropped will it send a BYE
