i received my X100P and Grandstream phone last week. i started configuring my * and with the help of ur mailing lists i was able to configure it. (when ever i got struck i searched this list and found my answer. thanks a lot and this list is awesome). i still hv a small problem and hope someone could help me out.
This is my setup.
RH 7.2 serving as my * server. i hv got couple of my laptops and desktops running MSN 4.7. I hv installed and configured X100P and Grandstream phone
the following configurations are working
MSN Msgr -> * -> MSN Msgr
MSN Msgr -> * -> X100P - PSTN
PSTN -> * -> MSN Msgr
PSTN -> * -> Grandstream (pl note)
the following are *not* working
MSN Msgr -> * -> Grandstream
Grandstream -> * -> MSN Msgr
GrandStream -> * -> PSTN
PSTN -> * -> Grandstream
the error i am getting in this case is
- Attempting native bridge of SIP/2003-b895 and SIP/2000-53e2
WARNING: File chan_sip.c, Line 1954 (process_sdp): No compatible codecs!
-- Got SIP response 481 "Call Leg/Transaction Does Not Exist" back from 192.168.0.58
and then the call drops. When i am making a call using Grandstream ph, it rings the other side when they pick up the phone the call then drops. then i get the above error message.
