We have two pri line and I want to see how asterisk distribute
outgoing call per channels
I meant it use first last channel 47 or it will use first channel?
Or it will allocate dynamically ?
Do you know if i want to use only specific channel for call out then how do i write dialplan ? I want to use channel 25 specific for my extension
DAHDI/25/XXXXXXXX or DAHDI/i2/25/XXXXXXXXXXX
I hope my understanding is not wrong!
(1) DAHDI/i2/25/XXXXXXXXXXX, is not a valid format for Dial. Rather it
should be DAHDI/i2/XXXXXXXXXXX and it would use a channel from span 2
(/etc/dahdi/system.conf) for outgoing call.
(2) To dial from channel 25 , use DAHDI/25/XXXXXXXXXXX
I appriciate your reply,
But believe me no one option works for me. I tried dahdi/25/XXXXXXX
but it still using pri first channel or anyother channel
In old zap school you can do that but in dahdi I don’t think you can.
Until unless you create g1 g2 … Group in chan_dahdi.cfg and map
Dialing DAHDI/25/xxxxxxxx will dial channel 25 only.
For ISDN spans I do not recommend doing that because your call will
fail if that channel is already in use when there may be other B channels
available for the call.
You should be creating groups for your ISDN spans.
It should be in some dial help but it is not. The syntax is
channel driver specific and every channel driver has its own needs.
I created that comment block in chan_dahdi.c since I could not find
it elsewhere when studying the code.
