Hi, I’m having difficulty intercoming a D40 (and possibly other Digium) phones. The system is successfully intercoming to Sangoma Phones, but the Digium phones never answer the intercom call.
In the asterisk log file, and SIP capture, all appears to be correct, but the phone never picks up (abbreviated log entries follow):
[2020-01-07 08:04:31] VERBOSE[C-0003e584] pbx.c: Executing [*803414@ext-intercom:37] Dial(“SIP/3153-00064fe1”, “SIP/3414,5,IA(beep)b(autoanswer^s^1(ring-answer,;answer-after=0))”) in new stack
[2020-01-07 08:04:31] VERBOSE[C-0003e584] app_dial.c: SIP/3414-00064fe3 is ringing
[2020-01-07 08:04:36] VERBOSE[C-0003e584] app_dial.c: Nobody picked up in 5000 ms
(extension 3414 is a Digium D40, Firmware 2.9.2)
