Hi,
There are 23 B channels in T1 circuit. from the dial-peer config, we can configure the call to T1 level (e.g. 6/0 or 6/1). can we config the call down to B channels level? (e.g. 6/0.12, channel 12 of 6/0)

by the way u can aggrate the pattrento match all of them in one pattren and then send it to that destination
so to match all the destination u posted here
do
[4,6,8][2,4-6]!
for example
dial-peer voice 9 pots
destination-pattren [4,6,8][2,4-6]!
then pot the port pr trunk u want (easy now)
but u gonna see a bit of delay when u dial becuase of inter-digit timeout because there is several possibalities to match or after u finish dialing put # to let the gateway that u finished the numbers but either way will work with one line and one dial peer
good luck

Trunk Groups
Trunk groups are used to group multiple voice ports or ISDN channels into a single logical target for an outbound dial peer, reducing the number of peers required. Each trunk group is configured with a "hunting scheme" that determines the order in which channels are selected
Trunk groups apply only to outbound calls. The gateway cannot control channel assignment of incoming calls
this is example from cisco press, cisco voice gateways and gatekeeper
Gateway(config)#trunk group Emergency
Gateway(config-trunk-group)#description B Channels reserved for
Emergency Calls
Gateway(config-trunk-group)#hunt-scheme round-robin
Gateway(config)#trunk group Standard
Gateway(config-trunk-group)#hunt-scheme least-used
!
! Controller config to select channels
!
Gateway(config)#controller t1 2/0
Gateway(config-controller)#framing esf
Gateway(config-controller)#linecode b8zs
Gateway(config-controller)#pri-group timeslots 1-24
Gateway(config-controller)#trunk-group Emergency timeslots 1-2
Gateway(config-controller)#trunk-group Standard timeslots 3-23
!
! Set additional voice ports into standard trunk group
!
Gateway(config)#voice-port 1/0/0
Gateway(config-voice-port)#trunk-group Standard
Gateway(config-voice-port)#interface s1/0:23
Gateway(config-if)#trunk-group standard
!
! Apply trunk groups to dial peers
!
Gateway(config)#dial-peer voice 911 pots
Gateway(config-dial-peer)#destination-pattern 911
Gateway(config-dial-peer)#trunkgroup Emergency 1
Gateway(config-dial-peer)#trunkgroup Standard 2
!
Gateway(config)#dial-peer voice 11 pots
Gateway(config-dial-peer)#destination-pattern 91[29]..[29]......
Gateway(config-dial-peer)#trunkgroup Standard
good luck

Hi,
Very very useful.
One question
Can I group the "dial-peer voice xxx voip" into trunk group? if so, how to configure it.
e.g.
destination-pattern 4405.
destination-pattern 651.
destination-pattern 866.
destination-pattern 62.
etc
They point to the same gateway. I need to create 10 - 20 dial-peers for those destinations.
