Hi
New to sccp. As the post states, I can’t get a 7921 to take calls. In the CLI, i get:
NOTICE[24056]: app_dial.c:1076 dial_exec_full: Unable to create channel of type ‘SCCP’ (cause 44 - Requested channel not available)
This is the only skinny WL phone on my switch. All my SIP’s talk to each other fine.
TIA
Dave
hi
any guesses on this one? 
Just looking to see if anyone has had actual success with sccp. Not having any here. This includes a 7960 I took a stab at configuring.
still having issues? I have chan_skinny working with my 7921G wifi phone using the SCCP protocol.
I might be able to help.
When Asterisk “can’t create a channel of type blah” it usually means that there are no (or no more) valid extensions at that channel.
For example you try to dial SIP/100, but there are not sip phones attached, so asterisk says cannot create channel.
In your case I believe it is because you did not associate your line to your device in sccp.conf
[SEP00D4VIC3]
button = line,312 ;adds line number 312 to device.
[312] ; This is where you create line number 312
You can view lines associated with devices by typing sccp show lines in the Asterisk CLI with chan_sccp v3.
