BToE is pretty nice. But let’s face it. Not always easy to work with. Especially when a service provider insists that a buried setting be configured so as to disable the manual concepts and default to automatic.
So, let’s figure out how to get an AudioCodes 450HD with the latest firmware (188.8.131.52.367) to play BToE with us like WE want, not how somebody else wants.
OOBE for a phone that is going to be qualified for SfBO is with the BToE pairing forced to “automatic.” This results in the button being greyed out when you go to MENU on the phone. In this mode, BToE pass-though mode works just fine. Web login to SfBO works as expected.
But what if you want to do something like, pair a wireless laptop with the handset device always CAT5 so you can just grab the laptop and go? Like a laptop is designed to work?
What we need to do is light up the BToE button so we can get a pairing code (essentially a representation of the device IP). Not exactly easy to find for those who don’t typically read 200+ pages of setup. Like me.
Hmmm… (page 113 of LTRT-14820 450HD IP Phone for Microsoft Skype for Business User’s manual ver.3.0.1.pdf) says
Going to the admin manual…. ( page 157 of LTRT-09943 400HD Series IP Phone for Microsoft Skype for Business Administrator's Manual Ver. 3.0.1)
And that does work to enable the BToE button.
The cfg file is available here – there is the semi-standard “download the file, modify the file with text editor, upload the file to phone routine.”
Here is how the phone cfg file looks by default…
And here is how it needs to look. After uploading the cfg file, the phone will restart and you can then manually pair. Remember that the manual pair code is case sensitive.
Make sure that your Office 365 admins, if that role is not you, changes your online policy for ip phones to enable BToE, and further more to not change the pairing setting. For more information see this.
BToE button greyed out, but automatic pass-through BToE works. You want control of that button so manual pairing is possible for wireless connections. Modification of the cfg file is required.
