Hello,
              My name is Abdul Rasheed, i am working on a voice recording solution using SIP trunk and BIB.  It was noticed that while running the solution for 1 or 1.5 months in one site,  the recording will suddenly stop  and when i checked it was found that after the ACK is recieved from CUCM , it will immedietly send a BYE closing the session and the reason for the BYE is  Q.850 Cause =65  when i checked i found that the cause=65 means "bearer capability not implemented"  i am not sure why this error coming up immedietly on a working system after running for 1.5 months.  Is there any thing in CUCM configuration should i verify ?
 
Thanks and Regards
Abdul Rasheed

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

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,

Dear Ahmed,
                          You have missed out a few messages during your SIP negotitations.  You need to go through the SIP trunk messaging guide available in the CDN website to implement those messages. 

regards
Rasheed
