This is a no-brainer, but I need to repeat it. The vendor that does not involve third-parties in the pre-Alpha compatibility stage may have their own valid reasons for doing so. Only I have a hard time believing such reasoning.
I'm encouraged by Nortel's positive approach to compatibility testing in early stage development. Toronto-based Nortelproved it again today by adding new members to its VoIP interoperability program.
Alpha Networks VoIP Gateway's efforts with Nortel will concentrate on working with Nortel's Multimedia Communications Server 5200 to develop and enhance SIP (Session Initial Protocol) services for customer-premised VoIP gateways.
Nortel-Dataflex collaborative efforts will center on teaming up Dataflex's Voice Integration at Network Edge (ViNE) suite of VoIP integrated devices with Nortel's MCS 5200. ViNE uses either SIP orMedia Gateway Control Protocolto enable voice and high-speed data over a broadband connection.
Getting these partners involved early in the game should prevent lots of problems later on.
