Hi all,
I'm having some strange DTMF behavior and wondering if someone can shed
some light on it. I'm dialing out and sending DTMF after the call is
established, and this usually works just find. But occasionally it fails
from a sipura 2002 and PAP2, but works from my Polycom 501.
Now looking at the channels when set up the only difference I can see,
is that the Polycom has a SIP Option set.
Polycom:
Format ulaw
DTMF Mode: rfc2833
SIP Options: 100rel
Spa
Format ulaw
DTMF Mode: rfc2833
SIP Options: (none)
Can some one explain what the 100rel is and how do I get the SPA to
invoke it if possible. I Googled this and came up empty.
Thanks,
Mike
