Well, we still don’t know, if we already reached a Vodafone-satisfying state. We have to clarify why the SIP header being displayed in the SIP trace shows
Diversion: <sip:[email protected]>;reason=unconditional
and the Asterisk log states the same header to be
(Diversion,<tel:+494321987123>;reason=no-answer;screen=no;privacy=off)
Do you also experience the same difference between SIP trace and Asterisk log, respectively?
I asked Vodafone for the example of INVITE.
In the meantime I’m going to set up an alternative SIP trunk on the PBX.
Stay tuned…
