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)# voice port 1/0/1
Router(config-voiceport)# trunk-group Group1 2
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.
