Direct outgoing calls to specific bri ports

I have a Cisco 2911 voice gateway with x2 two port BRI cards. I have two ISDN 2 circuits as per attached diagram.

I have x5 phones that need to use x1 ISDN circuit and another x5 phones that require to use the other ISDN circuit. I do not require to fail over from one Isdn to the other. We do not use MGCP, so this gateway is a H323 gateway.

How do I direct outgoing calls from specific phones to use each ISDN/BRI card accordingly? Is this achievable without using MGCP?

What configuration is required to utilise all 4 channels?

Hi Dennis

Hi Dennis

Do you have a previous thread you can send me on this topic as I have researched this and cannot find the answer you mentioned?

What would be the solution to this problem ie. COR, Trunk-groups or Digit Manipulation

Hi Dennis,

Hi Dennis,

I found the attached pdf that helps me direct calls to different bri ports by tagging digits at the front of the dialled number, but the issue I have now is I am unable to dial 999.

I don't want to use MGCP which I know would solve this issue. Any suggestions


Hi dawsonpettifer1 & all,


I have the same issue.

This is the config I added, by tagging digits in the front of dialled number, but still doesn't work.

Do you know what's wrong?
