Hello,
we have a small Asterisk Network where Siemens PBX's are connected via PRI
(Zap) to an Asterisk and
the Asterisk's are connected through IAX, so this looks like this:
Phone1 --- Siemens PBX --- Asterisk --- (IAX) --- Asterisk --- Siemens PBX ---
Phone2
Now, when Phone1 calls Phone2 all wents well until there is silence - then the
line seems to be death.
My users wanted to have some Comfort Noise. The question is, how do I generate
this comfort noise, and at which point? On Goolge I found some hints, that
comfort noise generation is a phone feature (regarding VoIP phones). But our
phones aren't SIP or other VoIP phones but normal Siemens Optiset phones,
and they can't generate comfort noise.
I suspect that I must generate the comfort noise in the VoIP part of the
connection, more precisely, in iax.conf.
Any suggestions or hints?
Regards,
Henry
