exten=>101,1,Dial(SIP/101,20) ;20 is timeout

=============

i registered account 101 and dial 102, my client use x-lite

but get error message from CLI
WARNING[3490]: app_dial.c:1759 dial_exec_full: Unable to create channel of type ‘SIP’ (cause 20 - Unknown)

any idea?

Both sip peers are registered? It’s possible that peer 102 is not registered, thus Asterisk doesn’t know where to dial it?
