2 different pri groups or trunk groups on PRI with Call Manager

[John Butterfield]

                   We are running Call Manager 9.x and I have a 2921 with a VWIC2 1MFT module.  We will have a 7 channel PRI coming into this card.  The provider will present them as 2 different channel groups.  One will be 1-6 and the other will be 7.  The purpose is to support 2 different company names on this circuit.  Channel 1-6 will have a different calling name from Channel 7.

    Can this be done in CCM so that I can create 2 different route groups, one that is associated with Channels 1-6 and the other is associated with Channel 7?

I've tried creating trunk groups under the PRI, but in CCM when I create a route group, it only allows me to choose ALL ports on the MFT as opposed to the different trunk groups or specific ports.

We are using MGCP by the way.

Thanks in advance for any advice.

Not MGCP, you need H323 for that.

No way to do such with MGCP

Then just configure the dial-peers as required and use a prefix to choose over which channels you want to send the call

IE

111.XXXXXXXX

222.XXXXXXXX

And keep the same in the dial-peers, so you can choose one or the other based on the prefix, then just drop it before sending the call out to the PSTN.

Ok, I was afraid you were going to say that.  Ok, I'll test in the next day or so, and see if I can get that going.

Thanks.
