  10. Solved Yealink and v15 pnp not working

    Hi Was a solution found to this problem? I have the same issue with three Yealink T42G phones. The 3CX server has a single NIC, and it receives PNP multicast from a Yealink W52P which appeares as a "new phone" on the phones node. The phones are on the correct firmware and have been reset to...

  11. Setting up Yealink W52P DECT

    Hi Still no success trying to register a Yealink W52P phone :-( I have followed all instructions trying to get a W52P to register with 3cx version 15.

  13. Yealink W52P Won't Provision

    Have you updated the Base station's firmware to the version supported by 3CX? When I obtained this phone I first had to use the devices own web based update tool to update to the supported firmware. Once done, it provisioned fine.

  16. Is it possible to recover Lets SSL Security key without a Version 15 backup?

    Thanks Ian Unfortunately not possible to recover certificate that way as I restored the drive from a backup made before 15 was installed. After this experience I think I would rather use my own FQDN and SSL. My domain is registered with Namecheap who do provide certificates, but I simply do...

    Thanks "aberry" I have been using 3CX since version 11 and have migrated to latest versions very smoothly. I am currently running version 14 on windows 10 pro. I attempted upgrade to version 15 and everything appeared to go fine. Unfortunately it simply did not work properly. Spent about 10...

  20. Confusion over the need for Server "CAL's" - Version 15

    Hi I am currently considering moving from 3CX running on Window 10 Pro to one running on Server 2012 R2. I have searched for information regarding 3CX's need for CAL's for each phone. I was reassured to conclude that it appeared that each phone does not need its own CAL. This information was...
