I have a CUCM 7.x with 2 dial peers, 2 Voice gateways. Three PRI's are currently plugged into each voice gateway. We have added 2 new PRI so now total 8 PRI's.
Where do you configure to have the new PRI's used as 1st prefrence for outbound calls. What should they be configure to?
Thanks for your help.

Hi,
Firstly from your description you mention that you have dial-peers, so we can assume that you are using H323 to configure your voice gateways. In order to understand your current outbound dialling, could you please provide the configuration the VGs, what is unclear is how you are already prioritising the existing PRI interfaces.
The are couple of options for configuring outbound dialing within H323, you can assign a specific preference under the given dial-peer, in this case you require a dial-peer for each voice-port and route-pattern. Alternatively you can configure each voice-port to be assigned to a trunk-group which included all PRIs, and each voice-port can have a unique preference so that a single PRI can selected.
For example the following example assigns voice port 1/0/0 and voice port 1/0/1 to trunk group Group1. Trunk group Group1 uses voice port 1/0/0 before using voice port 1/0/1 because voice port 1/0/1 has preference 1, which is a higher priority than voice port 1/0/0, with preference 2.
Router(config)#trunk group Group1
!
Router(config)# voice port 1/0/0
Router(config-voiceport)# trunk-group Group1 1
Router(config-voiceport)# exit
!
Router(config)# voice port 1/0/1
Router(config-voiceport)# trunk-group Group1 2
Router(config-voiceport)# exit
!Router(config)# dial-peer voice 100 POTS
Router(config-dp)#trunk group Group1
!
The preference would be to use trunk groups, specifically if you have multiple dial-peers configured for COR,
otherwise you will have configure a dial-peer for each destination-pattern that you expect to match for each
voice-port on the gateway. For example if you have a pattern for a specific international-pattern, you would
have configure at least four dial-peers for each voice-port (PRI interface) and particular preference for that
dial-peer, this seriously become un-manageable.
With the above in mind you can see that we first need to determine how you have currently configured your
outbound dialling.
Regards
Allan.
Hope this helps, pls rate helpful posts.

Sorry took me a while. The client has 2 Voice gateways with 2 Gatekeepers and CVP in mix. They are changing exisiting PRI's with one vendor and replacing with different vendor.
Today only VG01 is the only one makes outbound calls. The desire is to configure both gateways to make outbound calls. They have 2 PRI's each 4 total.
1) configure gateways to make outbound using all 4 pri's (how and where you do this)
2) Can we just unplug old PRI's and replace then with new PRI's assumeing the line config is same ?
Thanks,
Baseer.

Abdul,
In this case you can use preference to select the prefered pri on each gateway...
eg..on gateway 1 with 2 pri assume the voice ports are 0/0/0 and 0/0/1
you should configure
dial-peer voice 1010 pots
description National 10 Digit Numbers
translation-profile outgoing CLI-OUT
destination-pattern 901T
progress_ind setup enable 3
progress_ind alert enable 8
port 0/0/0:15
prefix 01
dial-peer voice 3010 pots
description National 10 Digit Numbers
translation-profile outgoing CLI-OUT
preference 1
destination-pattern 901T
progress_ind setup enable 3
progress_ind alert enable 8
port 0/0/1:15
prefix 01
!
on gateway 2 with 2 pri assume the voice ports are 0/0/0 and 0/0/1
you should configure...
dial-peer voice 1010 pots
description National 10 Digit Numbers
translation-profile outgoing CLI-OUT
destination-pattern 901T
progress_ind setup enable 3
progress_ind alert enable 8
port 0/0/0:15
prefix 01
dial-peer voice 3010 pots
description National 10 Digit Numbers
translation-profile outgoing CLI-OUT
preference 1
destination-pattern 901T
progress_ind setup enable 3
progress_ind alert enable 8
port 0/0/1:15
prefix 01
NB: If you are using CCM, you will need to configure CCM to point in the order that you prefer the desired gateway for outbound calls.
As Allan stated if you have multiple PRIs I suggest you use Trunk groups.
