Would Nconference or whatever the drop in replacement to Meetme have G729 issues. I guess the G729 to GSM depends on the provider. Using L3 or XO, I have never really heard any issues. On a double VSAT hop around the world with 10:1 or 20:1 contention on a small pipe, yeah, I have heard audio problems but I know for a fact that G729 is actually helping, not hurting. BTW, I do all SIP. Thanks, Steve Totaro
