Hello!
I have Cisco CP-8865 configured with asterisk. If I call from other phones connected to asterisk to this cisco phone, calls going well (because INVITE to cisco comes from sip proxy(asterisk))
But if I call directly to this cisco, without sip proxy, the phone ignores INVITEs.. Is it possible to allow incoming calls from all?
192.168.10.47 - asterisk (not asterisk which set as sip proxy)
192.168.2.251 - Cisco cp-8865
(sorry for bad English)

You should take a packet capture for both successful and unsuccessful INVITEs, directly on the phone port. Compare the two INVITEs and what the phone responds to them.

sorry for my late answer..
In cisco logs i found "Sender not recognized" it is mean cisco doesn't accept call from not sip proxy. But is there any configs to accept it?
