T41p and YHS32 voice Quality

[wyztech]

I'm trying this on a T41 and it doesn't appear to accept the value via a provisioning template. If I manually edit the vmp.cfg in the config.bin and reupload it to the phone, it works, but if I try to change it in the template, it doesn't. The config always shows headset_send = 29 even though my parameter has it at 8.

I did notice that the autoprovisioning.zip provided by Yealink says
### Only T28P/T26P/T22P/T20P Models support the three parameters
voice.handfree_send =
voice.handset_send =
voice.headset_send =
(this note isn't in thge 3CX Template)

Does that mean that it won't work on a T41?
