when calling by one of my E1’s getting something like that:
Zap/58-1 is proceeding passing it to SIP/test-093a5a30 -- Channel 0/27, span 3 got hangup request, cause 0 [Nov 10 19:31:27] WARNING: app_dial.c:746 wait_for_answer: Unable to forward voice or dtmf -- Hungup 'Zap/58-1' == Everyone is busy/congested at this time (1:0/0/1) == Auto fallthrough, channel 'SIP/test-093a5a30' status is 'CHANUNAVAIL'
Discovered that it happen only at this one E1 (Polish Plus GSM) and while remote number is BUSY or someone reject call.
On others E1 getting:
-- Zap/1-1 is proceeding passing it to SIP/test-09126ea8 -- Channel 0/1, span 2 got hangup request, cause 17 -- Zap/1-1 is busy -- Hungup 'Zap/1-1' == Everyone is busy/congested at this time (1:1/0/0) == Auto fallthrough, channel 'SIP/test-09126ea8' status is 'BUSY'
Any idea how to fix it?
