A codec issue would explain the "silence" if putting a call on hold actually 
works (ie the call is not dropped).

In SipXbridge try and limit your codecs or reorder them on the phone.  I 
typically set the following.
In Polycom phone profile
G.722
G.711u
G.729

In sipXbridge:  only allow
G.711u
G.729

That way G.722 is stripped for all external calls but for internal to internal 
calls you still have high-def.

By the way, has this box been modified for high-def MoH via freeswitch.  I 
wonder why MoH would try G.722 to start with considering the defualt MoH server 
doesn't use G.722.  I know Josh and a few others has success modifying it for 
G.722.
