801 calls extension 8000, after asterisk bridged the call.
801 wants to transfer call to 8001. For 3cx phones, no problem.
Does it use the same dialplan? like dial a new number?
which context? same as: 8000 dials 8001?
But using gateway, it did not work.
[Nov 8 14:59:40] WARNING: chan_sip.c:18325 handle_request_info: Unable to parse INFO message from email@example.com:5060. Content
== Spawn extension (users, 8000, 1) exited non-zero on ‘SIP/801-00000000’
What could be the problem? The gateway has a setting for transfer: internal processing, RFC2833, SIP INFO.
I tries 3 options. Only SIP INFO, asterisk print some error message. Other two options, asterisk keeps silent,
Thanks for help.
