Avaya Call manager sip trunk 403

Dear All,

We try to integrate Avaya to Call manager using SIP Trunk.

for now, avaya ip phone can call to cisco ip phone, but cisco ip phone can not call to avaya ip phone.

when i collect rtmt debug, it said

SIP/2.0 403 Forbidden(Invalid domain in From: header)

Is there any suggestion for this problem?

Terima kasih,

Anju

It seems the Callmanager IP address is not trusted by Avaya. Please check the avaya side configuration whether if it is configured with correct ccm ip address.
