Decoding Lync’s Client-Side Error Messages

Posted by on

Some of Lync’s Client-side error messages don’t really explain the reason for the failure. Here are a few and what they might be indicating. I hope they make your life a little easier:

Instant Messages

“<username> could not be found and this message was not delivered”

Lync-CouldNotBeFound

1) There is no such user at the recipient’s domain. There’s an instance of OCS/Lync there, they have an Edge, but you’ve simply nominated an invalid user – or guessed their e-mail naming format wrong.

2) There *is* such a user at the recipient’s domain – but they’re not enabled for Federation. There’s an instance of OCS/Lync there & they have an Edge. [TBC]

3) There *may be* such a user at the recipient’s domain – but they don’t have open Federation and THEY don’t trust YOUR domain. [In this example, my lab domain is not Federated with Microsoft].

Lync CU4 Database Update Error

Posted by on

My Topology here in the Lab started with a Standard Edition FE, and I later added an EE. Accordingly, the XDS is on the SE FE, which would be considered ‘unconventional’ in the outside world, and certainly highly undesirable if you’re aiming for high availability.

CU4 went on to the SE without any problems, but when I got to the EE server the Database Update failed with following error:

Audio file formats for Lync and Exchange

Posted by on

Lync and Exchange will let you customise and import new recordings for various greetings, voice announcements, messages, etc.

Here are the respective requirements for the audio file formats. The source is hyperlinked or referenced beneath each item. Yes, some of this is a cut and paste job.

Before You Start

Just taking any old audio file and converting it as recommended/required below isn’t necessarily going to deliver an ideal or acceptable outcome. You might end up with sibilants (“ess-ing”) or quiet patches. Any commercial audio production house will be familiar with the tricks for phone production, but if you’re doing it yourself: Continue reading ‘Audio file formats for Lync and Exchange’ »

NET UX2000 SIP Override Tables

Posted by on

Updated 12th December 2011. (Scroll to the bottom)

We’ve found here in Oz with the UX that occasionally a random failure code from the carrier is enough to block the entire gateway.

The NET faithfully interprets the applicable standards, mapping the ISDN failure messages to their SIP equivalents, then sends the resulting message to Lync.

Unfortunately then Lync – itself also dogmatically sticking to the standards – decides that the message indicates a failure of the entire route/gateway, not just a single call, and temporarily blocks the gateway for all further outgoing call attempts.

“Profiles for Lync”

This post is obsolete. ‘Profiles’ has been replaced by bounSky!

 

 

This post is WAAAAY obsolete. ;-) The latest Profiles post (1 Jan 2015) is here: https://greiginsydney.com/p4l-sticky/.

A free multi-user account management application for Lync.

If you’re following my exploits here you might have seen my “C-Change PHP” application, and the accompanying disclaimer “I’m not a programmer”.

I’m also not a C# programmer, and until a couple of months ago I’d never seen it before – and not programmed anything vaguely C-shaped since Granville TAFE almost 20 years ago, back in DOS where using ANSI colour was considered adventurous.

Still, with my usual stubbornness and determination (and plenty of help from several of my friends and the members of the Lync API forums) I’ve written “Profiles for Lync” (“Profiles”, or P4L for short).

This app fills what has been to date an annoying gap in the feature offer, especially for partners/integrators: with P4L it’s as easy as clicking a button to logout of Lync and log back in with another set of credentials – and even into another system!

Lync User Guides

Microsoft’s provided great, customisable training material for Lync. Download the Lync training intranet site and publish on your webserver, applying your own CSS to give them a look and feel consistent with the rest of your organisation.

If you don’t want to go to that effort, check out this link. From here you can drill down to individual pages that provide useful individual articles like:

Lync PowerShell query syntax

Posted by on

This is one of those posts selfishly for my own use. Until I start to dream in Lync PowerShell commandlets I’ll be referring back to this one to get the syntax right.

Today I need to see how many users were homed to a particular Front-End server, and here’s the commandlet I used. It demonstrates filtering, piping and an output/display filter of sorts.

get-csuser -filter {RegistrarPool -eq "<FE FQDN>"} | Select-Object SamAccountName

And while we’re on the subject of piping and PowerShell, if you’ve not yet realised it, Lync can sometimes withhold information! If you "| fl" and the output wasn’t as interesting as you were hoping, you might find "| fl *" more fulfilling.

Restoring a 232MT “Pyramid” phone

Posted by on

I’ve loved phones since I was a kid, and possess a small collection including my grandmother’s Commonwealth Ericsson and a candlestick, as well as the usual more modern plastic and Bakelite affairs. The mechanical aspects of payphones always fascinated me, so I have some of them here too.

I’ve had a “Pyramid” phone here for a while, wrapped in newspaper in a milk-crate, and I’ve been meaning to clean it up. Today was the day.
