Hi,
is ser supporting the SIP Request PRACK ? I get this Requests when i am forwarding an incoming call from a cisco router back to it (with an other number) --> the destination telephone rings but i do not hear the signals (ringing) on my calling phone. When the called phone accepts the call then everything works fine.
In more detail:
The cisco router sends 2 PRACK Requests: 1. to the phone that is the destination of the forward (after forwarding) 2. to the phone with the forwarding set
But not to the phone which initialises the call.
Regards, Reinhard
