VX says VVX “Not Acceptable Here”

Protocols and standards. We live and die by them, and while we can’t live without them, sometimes they can be a royal PITA. And so it is apparently, with Polycom’s interpretation of RFC4568 Session Description Protocol (SDP), with which I became all too familiar this week. I was called in to try and figure out …

Polycom VVX & Trio Time Zone Location Description

I was working on a Polycom VVX configuration file recently and it took me a while to find where the timezone cities were defined: all I had was a mysterious integer. I found them in the PDF “3725-49078-018a-uc-software-skype-for-business-deployment-guide-5-6-0.pdf” but for future reference I decided to copy and re-post them here. From the PDF: “The following …

VVX can’t call SfB Unassigned Numbers

As any half-decent taxidermist will tell you, there’s more than one way to skin a cat. And so it is with Skype for Business. The clever bit is determining the best method to use when faced with a given challenge. Occasionally you’ll encounter a complicated job-sharing or multiple-hop call distribution scenario that doesn’t fit the …

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 …

Mucking with MWI – Part II

In the process of migrating a customer to Lync recently we inherited an obligation to provide a *BIG* Message Waiting Indicator (MWI) light whenever a voicemail message arrived in a particular high-priority mailbox. That inspired me to embark on a campaign to see how many ways I could bring an external MWI light to reality. …

Polycom VVX gives SIP480 – Can’t be Called

A recent update to the Polycom VVX firmware for Lync has introduced a strange bug. If a phone running the affected version of firmware is used to log into a BRAND NEW new Lync account (i.e. a normal user account or a Common Area Phone), the phone appears to stamp some invalid call forwarding data …

Optimising the Polycom VVX for Lync/SfB

Polycom’s VVX family of phones is incredibly flexible, with a 23M Admin guide that spans 590 pages. I won’t say I’ve read *every* page of that, but I’ve spent weeks trawling the config options so as to assemble my “ideal” config for a VVX deployment operating as Lync peripherals. Philosophy My design philosophy for this …
