7937 supports lapel MIC kit. I had exchanged emails with the BU and here is what they had to say

Also, here are some comments (below) from Polycom on the use of non-Polycom wireless mics;
Based on email traffic, you’ve had quite a few requests for information about wireless mics. As I mentioned, we only tested with the Polycom wireless lapel mic (available in NA through standard channels such as Ingram, Tech Data or local resellers to include DMRs like CDW) and the AudioTechnica. The Audio Technica did not test well and we are not recommending it.
In general, however, I did get some feedback from our audio engineers. This should help you out.
The VTX1000/SoundStation2 support an external microphone via the AUX IN jack, when the device menu is set up appropriately. The 7937 supports this same function via its 2.5mm connector. This external mic can be wired or wireless, the only constraint is that this needs to be a “line level" signal.
- a. Most wireless mics are line level by design. Hence, most good
wireless mics will likely work fine. We've tested our own wireless (for
domestic market) and the Shure SLX (for international), to be able to
give a specific confident answer to this question, but the fact is that
many more will work.
b. Most studio and conferencing mics are "mic level", which is a much
lower level. They are normally amplified using a preamplifier module or
a sound mixer (for multiple mics). Consequently, a microphone plus a
preamp would work fine with the VTX1000/SoundStation2 or Rockpile.
Two examples of wired microphones are the Shure SM58 (classic microphone look)
or the Shure MX418 (very compact). They can be gooseneck-mounted, or on
a desktop stand. But there are hundreds that will work; these are just
the two we've experimented with recently.
