[Freeswitch-dev] Freeswitch capabilities

Hi Men! Looking for an advice of using Freeswitch ove Asterisk. I'm looking for a way to bridge a lot of TDM PRI calls usind SANGOMA hardware, and I found that Asterisk just is not so capable on high volume calls (10xE1 on 5xDualPort cards) . I suppose Freeswitch should be more capable of doind so. Asterisk eats full CPU on ~80 calls with no transcoding and no echo cancel. Is Freeswitch capable to do so and if yes can it reliably interoperate over IAX2 with other servers * and Freeswitch? Would be gratefull for any advice, With best regards, Anton.
