I am having an issue with the B-Channel Order selection when using a Trunk Group.
Under the Serial Interface, I have the B-Channel order set as Descending (Default).
When I have my POTS Dial Peer like this, it selects the calls descending:
dial-peer voice 1800 pots
port 0/1/3:23
When I have my POTS Dial Peer like this, it selects the calls ascending:
dial-peer voice 1800 pots
trunkgroup TEST
And the call fails, because the carrier wants the calls descending.
I am using a 8200 router running Version 17.15.3a
Anyone know why it selects the channels ascending when using a Trunk Group.
But selects descending when I use the physical port.
Thanks

On your trunk group add "hunt-scheme round-robin down" (or "sequential down" or "least-idle down" or whatever).
The "down" part of the command tells your hunting to use B-channels in descending order. If you wanted ascending order you'd use the keyword "up".
Hope that helps.

Thank you Maren.
That was it.
I thought I had looked at options for that command, and didn't see any.
But they were there as you described.
It is working as expected now.
Thanks again
