Tools such as the document server, which allows users to preload documents in preparation for a conference, are useful in streamlining document sharing during a call. VTel and VCon failed to incorporate NetMeeting seamlessly with the video application. The video connections worked fine, but once we started data sharing, the systems either went berserk or totally locked up. Unfortunately, this is unrealistic in today's video infrastructure. Most companies have invested in products from multiple vendors, and they need to communicate outside of the organization.
Interoperability is crucial.
When attempting to connect via IP, the only problem we encountered with TeamStation was that it would not answer a call placed from the VTel WG500. The WG500, however, was able to answer Intel-initiated calls just fine. We had great difficulty establishing a successful H.323 call between VCon's MediaConnect and either the Intel or VTel systems. While the audio generally worked, the video we received was poor. Conversely, VCon's MediaConnect was a clear winner in ISDN interoperability testing.
