Hi, Anybody got an idea of how many SIP calls I can run through asterisk on a Dual 3.6 Xeon (Dell 2850) if: - It doesn't perform any transcoding - Calls are g.729a - It doesn't have an interface to reg phone network (MGW in an other box) ie. everything is SIP to SIP. - Re-Invite is not allowed (I need the CDR's) - Uses Realtime (sip extensensions) on db on an other box - Exports CDR to db on an other box - Asterisk 1.2.5 How about if I move to a quad 3.6 Xeon (Dell 6850) Anybody's got a clue ? Cheers, John
