I am having problems interfacing a CallManager to a Rolm 9005 PBX via a VG200 PRI gateway. Do you know of any documents that will help?

CallManager 3.1 utilizing a vg200 h323 PRI gateway interface to a Rolm 9005 PBX T1 PRI card. Has this been done. Do you have the Rolm configurations needed?


Re: I am having problems interfacing a CallManager to a Rolm 900

If you have an HDVM module on a vg200

with T1 vwics and it connected to the pbx as wanted,

you shouldn't have a problem sending call through it.

1. I guess your ruuning PRI between the T! on router

and T1 on pBX.

2. You should get a voice-port created on the vg200 ( say voice-port 0:D)

3. creat a dial-peer voice for pots and voip.


dial-peer voice 1 pots

destination-patern .T


port 0:D


diale-peer voice 2 voip

description voip call-leg h323 connection to CCM

destination-pattern 408525....

session target ipv4:

4. add the gateway as h323 gateway on the call manager and forward all

pstn bound numbers to the vg200 for further processing.

Should be as straight forward as that.

For PRI and mgcp to work, you'll need to do pri backhauling and its not supported yet on CCM, mgcp

can work for CAS..
