Summary:                    Music on hold sometimes works, sometimes doesn't
Description: 
I'm using Cisco 7960s on my network, and ever since I upgraded to 1.6.2.13
(from 1.4) I've been having issues with calls and hold.  It seems that the
hold/resume feature SOMETIMES works to trigger MOH/stop MOH however, most
of the time, I end up with calls that are on hold with no music, or calls
that are on hold with music that can't resume.

I have attached a sip debug showing 3 attempts to hold / resume, the first
doesn't start MOH, the second does, and the third doesn't stop it.

rfc conform a=sendonly is sent by the phone and everything works fine.
