I am configuring Cisco IP Phone 7960 with Asterisk server. After configuration, when i call from SJphone to Cisco IP phone in direct mode, i am getting the call. But when i try through proxy mode, i.e., through Asterisk server, i can't able to connect between SJphone and Cisco IP Phone. I can make calls between two SJphones running on two machines, through Asterisk server. Here two SJphone have extensions as 277 and 278. The Cisco IP Phone has 121. Is there any problem with my configuration files. [b]SIP.conf[/b]  context=sipphone type=friend host=dynamic username=121 secret=121 allow=all  context=sipphone type=friend host=dynamic username=277 secret=277 allow=all  context=sipphone
