Lync Meeting- Schedule a Lync Meeting with Join by phone, without Enterprise Voice enabled

Just recently I came across a nifty little trick..
The requirement was for a Lync user who was not enabled for enterprise voice to be able to schedule meetings that offer a PSTN dialin number to meeting participants. Initially I was not convinced that this would be possible.
When scheduling a Lync Conference call from a Lync user that is not Enterprise voice enabled the conference invite is missing the Join by phone part of the invite.

I did expect that behavior since you would need Enterprise voice enabled for the user to experience PSTN calling (I know its not great logic but made sense to me at the time).

Arguably a user could have an Enterprise CAL allowing all the conferencing capabilities, including the Audio bridge access (Join by phone) – without having to be Enterprise voice enabled (perhaps no Plus CAL is available for the user in question).

So the good news is that it can be done, simply populate the Tel URI field for the user in question. You don’t have a voice or dialplan policy associated to the user, but don’t need that as the inbound PSTN caller would be calling the Conferencing Audio Bridge.


By simply adding a Tel URI to the users Lync profile you will notice that the Join by phone is now added to the Scheduled Lync Meeting



As of Lync 15.0.4675.1000 (2013 CU10) this seems to be the default behavior. Regardless of users setup. Even setting my user account to Audio\Video disabled and no Tel URI – the meeting invite still has the Join by Phone bits


About Paul B

My name is Paul Bloem and I am employed at Lexel Systems in New Zealand as a Principal Consultant for Unified Communications. I have been working on enterprise voice solutions for over 20 years. My first 10 years were spent working for a Telco in South Africa (Telcom SA). This is where all the groundwork happened as I was exposed to just about every aspect of telecommunication you could imagine. I develop an interest in PBX technologies and eventually became the go-to guy. Next, I had a 10 year run at Siemens South Africa, most of my time there was as a Technical Trainer. During this time VoIP hit the world stage, I had the privilege of introducing VoIP both as H.323 and later SIP across the Siemens HiPath 4000 solution stack. In 2008 I immigrated to New Zealand with my newly attained MCSE, I was ready to go where no PBX Techie had gone before. I was employed to explore OCS 2007 and that was pretty much the beginning of the end for me. I have been working on OCS and Lync ever since. My current role focuses exclusively on Lync and associated technologies.. That includes pre-sales, consulting, architecture and design, training and support. I even get to play in the development space from time to time - focus on play ;-) I was nominated as a Microsoft VTSP for Lync early in 2013 and also awarded Microsoft's MVP award for Lync in 2014.
