Replacing CS1000M with Avaya Aura

[AvayaCiscoAdmin]

Our Company may be replacing it's old CS1000 M SG with a new Avaya Aura Voip solution. We need to do the cut over in stages, floor by floor, building by building. Our CS1000M SG is Rls 6.0 but not voip. We need to tie the two PBXs together so that they can communicate as the M1 has all the working PRI's connected to it. If we run a tie trunk between them, using QSIG and a PRI, would that be sufficient? I assume that we would also need to add an MGATE card in the M1 for calls to/from voip to TDM. Any one have any experience with this or any ideas how best to do this?

The QSIG should do the trick between the two. That is how I have done this in the past with Nortel to some other system. You shouldn't need the MGATE card since the Aura will handle the IP to TDM before it sends it across the QSIG T1. You basically setup the T1 and modify the CDP tables on both sides as you migrate users. Just make sure you set one side of the QSIG to NET and the other to USER or SLAVE, else the D-channels will not come up.
