I think it really depends on whether you're looking for a multi-tenant PBX / Class 5 subscriber services box +/- with feature server, or more of a Class 4 style tandem router. If your primary application is core infrastructural routing, I would say neither the Metaswitch nor Sonus are particularly economical choices. -- Alex Balashov - Principal Evariste Systems LLC 260 Peachtree Street NW Suite 2200 Atlanta, GA 30303 Tel: +1-678-954-0670 Fax: +1-404-961-1892 Web: http://www.evaristesys.com/
