Some people thought still like the idea of having a traditional looking handset to pick up. For these people we supply either the Polycom CX600 or the Plantronics P540. Once our end users have the freedom to login from anywhere (home, coffee shop, train) then they start asking can they use their handsets there too.
The P540 is a dumb USB device so just taking it home with you and plugging into an internet connected and Lync cliented PC means that “it just works.” The CX600 is a different beast. It’s an IP phone using Power Over Ethernet (POE) that when on the corporate network finds our front end pool and allows you to login fully on the phone.
When at home then you have a few barriers to overcome to get the CX600 to login.
Barrier Number One
It’s a POE phone.
I would wager that not many people have POE on their home network. So you will either need a POE injector or a power supply for the CX600
Barrier Number Two
For a phone that has been setup at work this is no problem. The phone already has the domain name that it needs to connect and authentication details saved into its internal memory and when it boots up on an external network it simply finds the Edge server and signs in with the cached credentials
For a new out of the box phone we have an issue though. The sign in on the phone is your extension and passcode. The phone has no knowledge of what that extension number connects to and as such will fail to find the Edge server. The solution is to plug the USB cable into a computer that has Lync on it and then us the “better together” feature to pass the network credentials from the Lync client on the computer to the phone which will then be provisioned to find the Edge server and log in successfully in future.
