Hello,
I have the following topology:
IPphones <-> IPBX-1 <-> <-> IPBX-A <-> IPphones
IPphones <-> IPBX-2 <-> KAMAILIO <-> IPBX-B <-> IPphones
...
IPphones <-> IPBX-N <-> IPBX-X <-> IPphones
version: kamailio 1.4.1-notls (i386/linux)
I experienced problems regarding DTMF digits transport. DTMF is
transported through RTP data and it is not recognized at the end.
If DTMF mode is set to RFC2833 or RTP, Kamailio have nothing to do with it.
Does anyone could recommend me how to force the
negotiation between
Kamailio and IPBXs to be sure that IPphones and IPBXs will use another
method to transport DTMF (like OOB SIP INFO or RFC2833)
It's not a matter of Kamailio, it's a matter of SIP config on the UA side, you
must set DTMF mode to SIP-INFO if you want that it travels throught Kamailio
as SIP traffic.
