In our company we use SIP trunk with 1 line to make calls to mobile phones. It work through gsm gateway with 1 SIM card.
I made button like this:
[SIP/gsm1]
type=trunk
label=GSM
channel=SIP/gsm1
And it work.
But - when i make calls through, it stand green until callee pick the call.
But line is busy in both case!
In asterisk 'core show channels' that situation looks like this:
Channel Location State Application(Data)
SIP/gsm1-00000629 8903******0@office:1 Down AppDial((Outgoing Line))
SIP/1102-00000628 s@macro-recout:7 Ring Dial(SIP/8903******0@gsm1,,T)
2 active channels
1 active call
454 calls processed
Channel Location State Application(Data)
SIP/gsm1-00000629 (None) Up AppDial((Outgoing Line))
SIP/1102-00000628 s@macro-recout:7 Up Dial(SIP/8903******0@gsm1,,T)
2 active channels
1 active call
454 calls processed
So, as i understnad right - in asterisk my trunk channel stay in Down state, than, when callee pick up call, in Up state.
Is it bug in FOP2 or mistake in my config? What can i do to mark such calls right?
