Hey
guys,
I have a current
setup like this .
PSTN user calls in
to SIP boxes via PSTN Gateways
Gateway will send
the call to the OPENSER servers and in turn rings the SIP UA
IF SIP UA tries to
forward it out to the PSTN again , the problem i am getting now is NO ring back
on the CALLER . (called party (PSTN) rings and has no problem starting
conversation . Just that no ring back).
I am currently
making use of the UAC_Redirect in the openser server to route based on the 3xx
move temporarily message.
Is there a way to
send a provisional message to the calling party PSTN gateway (originating GW)
that it is trying / ringing so that the ORIGINATING GW will generate ring back
to the caller ?
Please let me know
if you can't understand . THanks for your help guys!
Regards,
Sam
