Hi Bogdan, Thanks. I wasn't aware of that. While sending a BYE from proxy on session expiration makes some practical sense, RFC 4028 has a MUST NOT clause on this (quote below). I'm not sure what problems this can cause. Perhaps, this behavior can be made configurable (i.e. by default OpenSER will clear its internal state only, but if this flag was set, it'll send a BYE as well).
8.3. Session Expiration When the current time equals or passes the session expiration for a session, the proxy MAY remove associated call state, and MAY free any resources associated with the call. Unlike the UA, it MUST NOT send a BYE. -- Raj Jain On Tue, Jun 10, 2008 at 4:18 AM, Bogdan-Andrei Iancu <[EMAIL PROTECTED]> wrote: > Hi Raj, > > well, openser can send a BYE - dialog module keep the call state and is able > to send BYEs on both legs. > > Regarding the Max Session Timer - take a look at SST module. > > Regards, > Bogdan > > Raj Jain wrote: >> >> On Mon, Jun 9, 2008 at 12:21 PM, Iñaki Baz Castillo <[EMAIL PROTECTED]> >> wrote: >> >>> >>> El Monday 09 June 2008 18:06:38 Kaeman Chris escribió: >>> >>>> >>>> Please let me know how can i configure this sip max session timer on >>>> the >>>> openser?
