H323 Gateways or CCME dial-peers

[ouhakheme]

Hello everyone --

We have deployed numerous CCMEs in the past , most using FXO ports. In order to be customer friendly, we would create a number of dial-peers for each local area code with a preference for each port. For example:

dial-peer voice 1000 pots

destination-pattern 9407.......

port 0/1/0

forward-digits 10

!

dial-peer voice 1001 pots

preference 1

destination-pattern 9407.......

port 0/1/1

forward-digits 10

!

dial-peer voice 1002 pots

preference 2

destination-pattern 9407.......

port 0/1/2

forward-digits 10

!

dial-peer voice 1003 pots

preference 3

destination-pattern 9407.......

port 0/1/3

forward-digits 10

!

dial-peer voice 1100 pots

destination-pattern 9321.......

port 0/1/0

forward-digits 10

!

dial-peer voice 1101 pots

preference 1

destination-pattern 9321.......

port 0/1/1

forward-digits 10

!

dial-peer voice 1102 pots

preference 2

destination-pattern 9321.......

port 0/1/2

forward-digits 10

!

dial-peer voice 1103 pots

preference 3

destination-pattern 9321.......

port 0/1/3

forward-digits 10

Once you add on long distance and 911 this can be a management headache. We have also tried using 9T with a 2 sec Interdigit timeout, but customers give us grief about that, and we still have to create dial peers for X11 and long distance.

What do you guys do? Is there a cleaner method of creating dial-peers.

Thank you.

Absolutely, trunk groups is the solution.

1 - associate the pots line to a trunkgroup:

voice-port x/y (or int x/y for ISDN port)

trunk-group

2 - in the dial-peer, use it instead of port:

dial-peer voice XX pots

trunkgroup

3 - optionally, define preference for the individual port inside the trunk-group in step 1

4 - optionally, define multiple trunkgroups with preference in step 2

5 - optionally, define an hunt-scheme for the trunkgroup:

trunk group

hunt-scheme least-used

Hope this helps, if so please rate post!
