[cisco-voip] question about transcoding

[James Grace]

We have a data center that houses the CM and unity (unified messaging) servers..  then we have an srst site that has all the ip phones.   There is no pstn connection or ip phones at the datacenter.  The 2 sites are connected by p2p T1s
  What do I need to do about transcoding so that the ip phones won’t run into issue with unity or Conference bridges?  The unity server has 72 VM ports. Not sure if this matters
