Polycom Trio – Service Unavailable adding Meet Now participants

A customer reported an interesting bug that found its way to me today, and in the washup it turned out that I was somewhat directly the cause. Ouch. The problem was that anyone hosting a “Meet Now” meeting on the Trio was unable to add participants. When they pressed “+ Add” on-screen button, the phone …

A VVX Courtesy Phone

It’s not an uncommon requirement to provide a “courtesy” phone in a public area. In a hotel it might be a “house phone”. In many deployments all the visitor does is lift the handset from its cradle and the phone autodials or “hotlines” to the required destination.

VVX – Missing files, config reverted

This error pops up from time to time with the Polycom UCS family of devices (VVX, Trio & SoundPoint) and it’s usually easily resolved. Whilst the phone won’t tell you what the problem is – it doesn’t name the file(s) it can’t find – your provisioning server is likely to hold the answer. In this …
