I currently have a UC520 running 12.4.(22)T with a standard PRI installed to the WIC port. We are adding a new office and will be using a new MPLS/SIP connection to UC520. What I need to know is if the system will support both the PRI and SIP at the same time. For legacy reason I need to maintain both connections.
I can't think of any reason why you couldn't do both. But- I am pretty green with this product so there may be some caveats I am not aware of. I am sure some one else here will chime in if they know of any.
