Hi all - Currently using ptp T1's as my main WAN links. We basically put 12 channels of voice/12 channels of data on each link - using an add-drop csu - the voice is from digital switch from fujitsu - the add drop connects to a T1 card on the switch.
Looking to hopefully move to MPLS to get some of the great advantages that service offers - but I'm confused as to how I'm going to get that legacy digial voice over the circuits. A friend a mine said it would be pretty simple - buy 'some type of wic' for the router, do some extension routing/conversion on the router - for example - if you're trying to dial extension 4xxx - route that to ip segment 172.5.x.x.
Can't find any docs or info about this anywhere - probably because I'm not even sure what the terminology is for that type of 'digital voice'/router integration. If anyone could point me in the right direction, I'd be most appreciative.
