[asterisk-users] SIP 420

[Dovey Forman]

Hi;



I am running asterisk 1.6 from Fonality (Trixbox PRO).



I am trying to initiate a call FROM a softphone client to asterisk (either
an internal 4 digit extension call) or an outside line via a SIP trunk.



In both cases, asterisk rejects the call with a 420.

In this case, it’s a call from x3992 to x4415



Does this require a change on the softphone for x-call-detail?
