Hello,
can anybody tell me some reasons for the above error. Why does a SIP message get a Q.850 cause =65 (bearer capability not implemented) error?


Regards
Rasheed

Hello Abdul Rasheed;

i have the same bye message with the same reason, but my case is
1- SIP Trunk send me the invitations
2- my sip server response with 200 ok
3- SIP Trunk sent to my ACK 101 then he sent to me bye message and he cotinue in sending it.

i read about that my 200 ok response for the invitation should have the SDP and codecs, and if these codecs are not compatable with cucm
you will get that bye message.

my case is

1- i created SIP Trunk and give it my pc ip.
2- i run my sip application on my pc .
3- i got two invitations for the call on ip phone with automatic recording
4- i sent 200 ok for these two invitations
5- cucm sent me ack 101
6- cucm continue sending me bye message .

please if you ses that i missed any thing here,
like should i configure any thing in network or in my sip SAILFIN server or in CUCM configurations, tell me please,
Thanks,

thanks Abdul Rasheed for your reply, now it is working, and the rtp streams came to my recorder pc.
but my problem is that i do not know how to save these rtp streams as a file [wav or mp3]., so if you know away to do please tell me to study it.
thanks again for your help
