PBX with Router: Multiple trunks

Unanswered Question
Jan 6th, 2008


I am currently working on voip setup. I connected a router with a pbx through a Pri (qsig). I configure dial-peers both for voip and pots. so when a call come to router, it matches the pots dial-peer and forward call to pbx on specific port that i mention in dial-peer.

Now my question is if have 3 trunk with the same pbx. One way is that i configure 3 pots dial-peer with same destination and define all 3 ports in them. like

dial-peer voice 10 pots

destination-pattern 3...

port 1/0

dial-peer voice 20 pots

destination-pattern 3...

port 1/1

dial-peer voice 30 pots

destination-pattern 3...

port 2/0

but i believe this is not the way. Please tell me the actual way to assign multiple ports for a dial-peer.

Best Regards

I have this problem too.

The proper way, it's trunk groups:

voice-port 1/0

trunk-group pbx <-- repeat for all voice-ports

dial-peer voice 3 pots

destination-pattern 3...

trunkgroup pbx

Then under "trunk group pbx" you can configure additional options like translation-rule, hunt schemes, etc.

Hope this helps, please rate post if it does!

Hi, i have the same situation, I duplicate the dial peers adding the preference command.

dial-peer voice 30 pots

destination-pattern 3...

preference 0

port serial 0/1/0:1

dial-peer voice 30 pots

destination-pattern 3...

preference 1

port serial 0/0/1:1

mmmm but i supose that this solution is not the best, then again, please tell me the best way to assign multiple ports for a single dial-peer.

Thanks :-)

Trunk-group under voice-port. The reference it in the DP (do "no port" first).
