SfB 2015 Server Update – May 2019

SfB 2015 Server Update – March 2019

Our January release took the SfB 2015 Server to 6.0.9319.537, and now we have a March update taking Core Components and UCWA to 6.0.9319.544. (I thank Luis Ramos for bringing this to my attention.

SfB 2015 Server Update – January 2019

This week saw the release of an update for SfB Server 2015, taking the server up from 6.0.9319.534 to 6.0.9319.537 and updating 8 components on my Standard Edition Front-End.

Test-EdgeConnectivity.ps1

The larger and more complex your on-prem SfB installation is, the greater the likelihood of encountering firewall problems. If you run this script on your Front-End server(s) it will: query the topology to find all of the Edge servers. (Add the “-site” switch to only retrieve those in a given topology site) initiate a TCP …

Lync 2013 / SfB 2015 Client Update – June 2018

Our May client update took us to 15.0.5031.1000, and now Kb4022170 increments us to 15.0.5041.1000 – but there’s a trick to this one: see “Before/After”. What’s Fixed We have just one update this month, but it’s a doozie and surely a Godsend for some of you: Kb4294971 Skype for Business 2016 or Skype for Business …

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 …

Adding Direct Trunk Select to Skype for Business

At about the same time any given Skype for Business deployment gains its second PSTN gateway / Session Border Controller, the old diagnostician in me wants a means to be able to directly send calls to each one individually. By being able to directly focus my outgoing calls on just one SBC I can confirm …

Event 18456 – Start-CsPool Error Failed to Connect to BackEnd

I hit an expected snag recently where I wasn’t able to get an existing SfB 2015 Front-End pool to start after growing it from 1 to 3 servers. Coincidentally I’d performed this same job for another customer maybe a month prior and it had gone off without a hitch. Not so this time. Try as …

SfB 2015 Server Update – March 2018

Our March 2018 update nudges the server up from 6.0.9319.510 to 6.0.9319.516 and updates 7 components on my Standard Edition Front-End. It doesn’t seem to be officially called CU7, but so far Martin and I are going with that. I’ll update the post if I’m advised to the contrary. CU6 HF2 it is, thanks Tim! …
