We have a CUCM 7.1.3 cluster at the head end and a handful of CMEs at branch offices connected via MPLS. I dont have the time or resources at the moment to convert each over to SRST. Our users are really wanting to start using 4 digit dialing between offices and I was wondering if just updating the dial peers on each CME to connect to each other over the MPLS links is advisable?
Any advice is appreciated, thanks!
Absolutely, as long as you do not have overlaps in your dial plan you can do this. Just make sure you do not accidentally create loops with wild card matching.
