Please help me. I'm trying to configure Cisco 7942G phone with Asterisk. (SIP image)
Phone registered and work well for calling. But i cant make softbuttons work ok.
I need a few functions like a Pickup, Transfer, CFWdAll and as first step i cant bring CFwdAll button to work.
When i press this button and enter a number - i heard a busy signal and in logs i can find this
[Oct 4 02:18:21] NOTICE chan_sip.c: Call from '1001' to extension 'x-cisco-serviceuri-cfwdall-1005' rejected because extension not found in context 'from-internal'.
How to bring this function to work?
