VoIP via 7204vxr

Unanswered Question
Mar 25th, 2008

Hi All,

Could it be possible to use my 7204VXR router for routing calls from Avaya Definity phone system between our intranet connections on an E1 pipe?

I will be going to connect my 7204VXR router to the DS1 board of my Avaya Definity,our intranet end will have the same setup as well.

My problem is i don't know the proper configuration on the E1 interface side & the Avaya interface side.

Could someone give me a sample configuration on this setup if ever this is possible?

Do you have already the PA-VXA, PA-VXB, or PA-VXC needed to make voice connections on a 7200 ?

card type x/y E1

controller e1 x/y

clock source internal


int serial x/y:15

isdn protocol-emulate network

Then check "show controller E1" and "show isdn status" if it came up.

also i have multi-channel T1/Pri card with 2 ports.

How would i configure if my setup is like this?

1. PA-VXC-2TE1 > inbound or going to intranet end

2. multi-channel T1/Pri will be going to Avaya/DS1.

Is it the right setup?.How should i configure my VXR Router?..

Hi, the PA-VX connects to PBX. The other card is of no use for voice. The rest of the setup depends on what you want to do and what other systems you have.
