We are using MVP210s and MVP130s with a SIP softphone called EyeP. The calls cannot be completed because the marker bit isn't getting set in the RTP section.

This was Fixed in firmware version (6.07.c9) and corresponding software version (x.07). This firmware and software along with instructions can be downloaded from our Web sites at:
