Correct - you should be using PJsip. Also as far as changing extensions, you can run into the same issue even if you use the same extension number but you change the channel driver from SIP to PJSIP. This is how I've accomplished the task for remote phones that you can't touch. From your EPM, issue a reboot. Then real quick, you change the extension to use PJSIP, go to EPM, and then do a rebuild. If you do it properly, the phone will then grab the new settings and reconfigure itself and work just fine. You can of course do the same thing if you are changing the extension number on it.

There's a good bit of dysfunction going on, such as two weeks after starting to look into what's needed for configuration manager there's still no authoritative answer on "talk to this person to see what Microsoft licensing we have." 😛

I'm trying to get an idea of what's needed myself, and most of what I found is in relation to those who already have System Center and having current SA entitles you to Configuration Manager Current Branch.

The timeline.

2019/02/27 09:23 - I posted on the FreePBX community. 2019/02/27 15:13 - Another user commented they also had this issue. 2019/02/27 16:31 - I submitted a support ticket. 2019/02/27 17:03 - Sangoma replied stating this was not any kind of known issue and I needed to install their SSH key package to let them check the server. 2019/02/28 08:52 I replied that I had added the SSH package and updated the firewall to let them connect. 2019/02/28 09:49 Sangoma replied that the files were missing on the remote server and showed the log error. 2019/02/28 10:05 Sangoma replied that an internal trouble ticket was created. 2019/02/28 15:58 Sangoma replied that the issue was resolved. 2019/02/28 19:26 I confirmed that the firmware was downloadable

This is not any kind of response time that I can complain about. I do wish there had been known information on how to find the EPM download errors. I would have likely been resolved much quicker.

That's why I posted here. Search engines can get this out there.

/sigh. The expected answer.

I know that EPM is a huge pain in the ass. But that is also why I willingly pay for it.

Glad to hear it. No better way to kick off a weekend!
