Switching to Integrated Voice/Data Circuit with PRI Handoff with Cisco UC540
Posted on 2013-05-18
With our UC540, we have just used an "old" PRI that has been in place for ages plugged into a VWIC2-2MFT-T1/E1 that we have in our UC540. Configured the PRI settings and it's worked fine.
And the data /WAN portion was a separate connection.
We are now switching to an integrated voice/data circuit (IP Flexible Reach by AT&T) but we won't use the data for now, sometime in the future we may use it in our firewall as a redundant connection but that's TBD.
What I'm concerned about now is the connection specifics from the AT&T ISR to the UC540 for the PRI network cable. The circuit comes into AT&T's Cisco 2900 Series as one connection and then their ISR splits off the data and the PRI for us, and provides the separate PRI connection.
What will be required physically to connect to the UC's VWIC2-2MFT-T1/E1 port, just connect the PRI cable from AT&T's ISR?
Should there be anything special we need to do configuration wise with the new PRI?
