Actually, We don't have one. We have it's big brother the VCX. and yes, it is a hybrid that uses the H3 protocol and not even a true H323, But the latest software load brings in a true sip stack and a few other things. I wouldn't have recommended using it until now, because it is still missing some functionality, but it costs about what a small keysystem costs and with most of the cost in the phones anyways which are dual mode H3 and sip. Your investment is better spent on something that grows. In terms of Avaya and Mitel Pricy as he(( and they are missing functionality as well. and to turn the table about Mitel and Nortel --> Cisco makes more routers then anyone, doesn't mean that I would buy one. or their VOIP for that matter. if you want the ultimate in flexability though GO OPEN SOURCE ASTRISK it is just as developed as any other platform. I would, in my infinite wisdom split out the Gateway and Sip Proxy functionality into two boxes, or three then you could do ANYTHING you want.
