RTCP PacketLength extends past end of buffer

[Korbyn]

A client is having problems with Skype for Business Response Groups and VVX phones running 5.4.4.3041 firmware.  The I can't find anything wrong in S4b, just the Monitoring reports indicating that the two internal devices cannot estabilish media.  In the phone log of the devices, I'm finding numerous entries like below:

0728175749|so   |4|00|soStream: RTCP PacketLength extends past end of buffer. Type=0 PLen-4=296 Pos=32 BLen=43
0728175749|so   |4|00|soStream: RTCP PacketLength extends past end of buffer. Type=232 PLen-4=222800 Pos=32 BLen=91
0728175749|so   |4|00|soStream: RTCP PacketLength extends past end of buffer. Type=0 PLen-4=304 Pos=32 BLen=43
0728175749|so   |4|00|soStream: RTCP PacketLength extends past end of buffer. Type=165 PLen-4=171688 Pos=32 BLen=91
0728175749|so   |4|00|soStream: RTCP PacketLength extends past end of buffer. Type=0 PLen-4=312 Pos=32 BLen=43

Kinda seems hand in hand with the following CDR failure:

The call was terminated after establishment due to a media timeout between the
two internal endpoints. This can be caused by a failure of one of the endpoints
or a loss of network connectivity

Any inspired thoughts?
