IMHO, In your environment I would recommend to use several
Gateways (Cisco, Quintum, whatever you choose) to concentrate and do the
transcoding, and use * to switch them and do the other stuff you need. A
lot of times where seen in the list people that measure the load on *
servers that cannot do more than 60 channels at a time. And personally a
do trust more on a GW than in * to do PRI.
