Problem with cisco 3905 SIP Phones

Hi,

I have registered 10 cisco ip phone 3905(SIP) and 2 7945 (SCCP) on CUCME 9.1 . Communicaton between 3905 and 7945, and outside to PSTN works. i have configured dial-peer to other call manager 6.1. calling from 7945 to phones registered on call manager(7911) is working perfectly. When I make a calls to phones registered on call manager(7911) ringing is working but i cannot established connection (audio drops). Calling from 7911 to 3905 is workink also. Codec is OK, CSS is OK. sip to h323 and h323 to sip is ok. I think that i have some problem with SIP signaling. please advise.
