Hi
I’m try to do an outbound call but i get this error.

app_dial.c:2702 dial_exec_full: Unable to create channel of type ‘SIP’ (cause 20 - Subscriber absent)

here is the Context:
exten => _X.,n,Dial(SIP/1210@outbound_call)

Sip.conf :
[outbound_call]
type=peer
host=XXXXXXXX
port=5060

Any idea on the root cause or how to trace it?

You are using an obsolete channel driver. Most people here have forgotten about it.

Subscriber absent normally means they haven’t registered, but that isn’t the case here. I’m not sure if a failed quailify also produces the same error.

if qualify=yes and it is not responding to options calls will result in Subscriber absent
