For the last day or so I have been trying to provision a Yealink T42S phone but with no success. A little backstory here, we have several employees that use the Yealink T42S and a few that have the T46S. So far, I have not needed to re-provision one of the T46S only a T42S. Recently two employs quit and one of the other techs decided to ‘help out’ and removed them from 3CX. He deleted their extensions, so they were freed up. I did not think much of this and a few days go by, and I now need to provision one of the two T42S phones. However, I do not seem to be able to do that. It’s important to note that this employee being setup will be a remote person, so the Provisioning Method used is Direct SIP (STUN – remote). Just as I have done many times before. So, after failing one to use the method that I have used in the past, I checked the 3CX guide, after all, things change so there might be something new. I took the setup step by step from the following guide: https://www.3cx.com/sip-phones/yealink-t4-series +Phone > Select my Yealink T42S and add the MAC address. --Event logs show everything is okay… (Again per the doc.) # 3CX Phone System Management Console ID: 10018 # RPS request for Yealink T42S IP Phone of Fun Cat (1005) delivered successfully Now here is where things seem to diverge from what I am used to, it does not say that I need to put the link in the T42S’s Auto Provisioning settings. I do however do this because how else if the phone going to know where to look to be provisioned. I use the provided Provisioning Link: https://funpuncat.3cx.us:5001/provisioning/1p999mn2Qn18bd On the T42S I navigate to Settings > Auto Provisioning and add my link to the Server URL then confirm to save the settings. (In the past I just clicked the Auto Provision Now button at the bottom of the page. Then the system does its thing and done… that didn’t happen. Steps 7 & 8 never happen on the phone. Even if I try the Auto Provision Now option nothing happens. The phone’s web interface will tell me it is provisioning, but nothing happens. The page reloads after a few seconds with all the settings I saved. There is an option on the Auto Provisioning page that is for the username and pass. The second time around I entered the extension number for the user: 1005 and the Vmail PIN for the pass: 1234 Still nothing. I have run the firewall checker and everything there is good no issues at all. I have checked the settings on other T42S phones, and it’s the same as I am trying here other then they are provisioned and working. Here are the versions of my 3CX and phone. The system is installed in AWS. I thought to restart all the services but this also made no difference. I found on the forum someone else had a similar issue. But what helped them did not help me: https://www.3cx.com/community/threads/yealink-t42s-will-not-provision.50140/ 3CX Ver: PRO 15.5.3849.1 Yealink T42S FW: 220.127.116.11 I really hope this is something simple and I’m just missing something very simple. Any and all help and suggestions are welcome. Thanks, in advanced.
