Switching to Integrated Voice/Data Circuit with PRI Handoff with Cisco UC540
Hi,
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?
15.1(2)T4 (IOS), 8.20 (UC540 Software Pack)
Thanks

Will get the info on current ckt and check one against the other, thanks.
The AT&T (2900 series) will handle the handle the PRI handoff. The UC isn't configured now and will not be with the new, configured for SIP Trunking, solely voice with PRI and DIDs.
Unless the conversion from PRI back over to combined service circuit is considered SIP?
I use a combination of CCA and CLI or manage the system.
Thanks!

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
You may have to just adjusts minimal handoff configurations.
Presumably the 2900 router will handle the sip trunk to AT&T versus having the uc540 have the SIP trunk configuration within the E1T1 configuration.
Are you using CCA or cli to manage your system?
