At one point it worked, but now I am unable to provision my Yealink T42 phone from within 3cx. 3CX sees the NEW phone. I have tried assigning an extension, but nothing happens on the phone. I have also put the 3cx provisioning link in the phone to no avail. The only thing that seems to work is manually provisioning from the phone web page using the login, password and server IP. I haven't tried to provision a phone for about 2 months and the only thing that has changed on the server is an Acronis Backup installation and a new Backup hard drive being installed. I have tried a couple different phones to make sure it's not just a faulty phone. Any suggestions or ideas?
