Call Manager with at&t IP Flex

[Voipnow]

Is anyone familiar with implementing Call Manager with at&t's IP FLEX? From what I understand - Existing PRI terminates on 2811 router. In Nortel world is this equivalent to Digital Trunk Interface card? IP Flex includes Cisco router with T1 card for voice and FE card for internet. Do I connect from new router to old router? Where does the data connection from the at&t router connect to? I don't know much about the data connectivity on the Call Manager.

Since a new T1 is being delivered via the T1 module on the new router, the old router will get eliminated if all it did was house the old PRI.
The internet connection would typically connect into a firewall.

Agree with the internet firewall connection since that is outside the Call Manager control but what am I connecting the voice T1 portion of the IP Flex router to? I was thinking it would still go to the existing router which is essentially the PRI card on the phone system.

Yeah you would connect it to the existing router using the VWIC module in it.

WIll the Vwic port accept a standard T-1 crossover cable? I would use pins 1,2 and 4,5.

 

[whykap]

yes it does

This connection will need a firewall as it is open internet. We had issues, the issues was lack of documentation for our configurations.
