302 is because the call has not been answered. REFER can only be used for answered calls.
I saw that on Transfer documentation. The call cannot be answered, because nobody can do that. THerefore the call should be forwarded.
Any possibility to tweak that behaviour via dialplan configuration?
I’m trying here and there, but nothing works.
The Adress 194.XXX.XX.143 represents the server IP where asterisk is running.
Regarding wrong contact field I’ve found this discussion from last year: Problem to transfer call with pjsip
