Below are some notes from my quick tests of the new UCS 5.0.0 Better Together over Ethernet.
Q. What are steps to initially pair a VVX and Lync Client using BToE?
A. Below are the steps:
- Upgrade VVX phone to UCS 5.0.0
- Install the Polycom BToE Connector software on the PC to be paired
- My PC gave an error on running the “Polycom BToE Connector” software
- Plug the PC to be paired into the VVX PC port
- Now initiate pairing process from the VVX phone by pressing: Home | Settings | 3-Features | 5-BToE
- when the pairing is activated the 1st time the “Polycom VVX Phone” driver will be loaded
- Now on the Lync client on your PC it will pop up and ask for your NTLM credentials (just like Lynce Phone Edition devices)
After the pairing the Polycom VVX Phone will show in Devices.

Q. What happens if the PC is unplugged from the PC Port in the VVX phone after pairing?
A. Every time the paired PC Ethernet is unplugged from the VVX PC Port you will need to “re-pair”. This is made easy by having a BTOE button in the “More” menu.
Q. What happens if the Polycom BToE Connector tray software quits running?
A. If you exit the Polycom BToE Connector tray software, the pairing is lost. (so the Polycom software needs to be running at all times)
Q. What happens if a call starts on the VVX and you try to escalate to a video call?
A. When I tried to escalate a call from audio to video call, the call dropped from the VVX, but did not seemed to move to the PC (it did not disconnect) but seemed to loose audio. (bug?) As noted below
Q. Can BToE Paired device act as a USB Audio Device?
A. In this version of Polycom VVX BToE no. Polycom has communicated this is coming in future versions.
Q. Can the VVX Phone be on a VLAN separate from the PC and BToE still work?
A. I have not tested, but I see no reason why not. It appears to me that the only requirement is that the paired PC is plugged into the PC Port of the VVX phone.
Q. Will the Polycom VVX BToE functionality work with the Lync 2013 SDK (client side Lync SDK)?
A. From our quick tests, the Lync SDK works with BToE implementation. Since it appears to use a “virtual” USB connection this is as expected.
Q. Does BToE (UCS 5.0.0/BToE v1.0) work in a VDI/RDP/RemoteDesktop scenario?
A. At this time this scenario does not appear to be supported as the PC that is paired with the phone must by physically plugged into the PC Port on the VVX.
Q. What Ethernet Traffic does pressing “Pair” on the VVX generate?
A. From my Wireshark capture it appears that the VVX is initially sending a UDP broadcast packet on Port 2081. (show below) After that the phone and pc seem to communicate on Ports 24801 (from Phone) and 56xxx (from PC).
Misc Notes and Concluding Thoughts
- Pairing was lost when Laptop went to sleep
- It didn’t notify me that phone and Lync client users were mismatched

UCS 5.0.0 has introduced version 1.0 of BToE. This is a big leap forward for Lync Qualified IP Phones.
