multiple FXO ports to a PBX

We have a 3640 router with 4 fxo ports which we are connecting to a PBX over those links. Is there a way to have these ports all follow the same dial-peer (destination pattern) and use them in a round robin type fashion? If so, a sample dial peer would be great.

Re: multiple FXO ports to a PBX

Its called hunt-group or dial-peer hunting. The configuration is simple.

1. create four dial-peers either pots or voip based on your implementation.

2. use the same destination-pattern on all four.

3. specify the preference value on the dial-peer. i.e which dial-peer is prefered first.

1 is higher priority than 2

4. add you ports or session target as expected.

THe dial-peer now is ready to hunt, if a call comes on 1, the next prefered port is used

for the second call and so on an so forth.

If you want equal roud-robin then don't use a preference all make choice of

dial-peer equal.

example

dial-peer voice 1 pots

destination-pattern 9T

preference 1

port 1/0/0

!

dial-peer voice 2 pots

destination-pattern 9T

preference 2

port 1/0/1

!

dial-peer voice 3 pots

destination-pattern 9T

preference 3

port 1/1/0

!

dial-peer voice 4 pots

destination-pattern 9T

preference 4

port 1/1/1

!
