Trunk Group Config guide

[Kaushik Ray]

Can anyone please send me a link for configuring trunk group to allow each DDIs on each E1 channel?

I believe i saw this comment somewhere that the following dummy pots and voip is needed as well but cannot find that as well

dial-peer voice 1 pots
 incoming called-number .T

dial-peer voice 2 voip
 destination-pattern .T

Any help will be much appreciated.

The config of the controller is good. You won't be able to match '*' in the dialpeer. That is the reason for asking to prefix a code like 010 to the called number.

On each gateway you should have dial-peers as follow (make sure you don't have superseding dialpeers):

dial-peer voice 6001 pots

description **** CHANNEL 01 *****
 trunkgroup TRUNK1

 incoming called-number 0011...
 destination-pattern 0011...
 direct-inward-dial
 prefix 1
!

dial-peer voice 6002 pots

description **** CHANNEL 02 *****
 trunkgroup TRUNK2

 incoming called-number 0101...
 destination-pattern 0101...
 direct-inward-dial
 prefix 1

!

dial-peer voice 6003 pots

description **** CHANNEL 03 *****
 trunkgroup TRUNK3

 incoming called-number 0111...
 destination-pattern 0111...
 direct-inward-dial
 prefix 1

Kaushik - First of all if you are talking about inbound call routing that's carrier controlled.

If you are talking about outbound based on CLID then why do you want to use trunk groups and not utilize just the dial-peers to send the outbound calls to required E1 lines. Trunk groups are generally used to bundle together E1 lines.

I suppose you are using CUCM for call control. You can create incoming VOIP dial-peers based on ANI and then setup translation rules to prefix a digit. Your outbound dial-peers will route based on those digits.

For example: 1111 > Incoming dial-peer 1 selected, prefixes 9 > Outbound dial peer(destination-pattern 9.!) 10 matched, call sent to port 1.

2222 > Incoming dial-peer 2 selected, prefixes 8 > Outbound dial peer(destination-pattern 9.!) 20 matched, call sent to port 2.

Let us know if you need further help on this.
