Sonus is top of the line and most of the major IP carriers have migrated to Sonus from whatever else they used to run. Like many of the best in breed, they aren't cheap (hardware or support), but its reliable and very scalable. I haven't worked with the NBS SBC but it's fairly widely deployed now as well. If they are a little too high end for you, I'd recommend looking at Metaswitch, but of course the best platform will depend on what you need. -Scott From: voiceops-bounces at voiceops.org [mailto:voiceops-bounces at voiceops.org] On Behalf Of Kevork Belian Sent: Friday, July 01, 2011 5:52 AM To: 'voiceops at voiceops.org' Subject: [VoiceOps] I need feedback about Sonus Hi all, Currently we are running Cisco PGW-based voice network and we are thinking of migarting to another platform.
