Are you referring to a call being put on hold? If so this is correct. 
Internally the musiconhold just becomes a different source of audio, the 
fact it is on hold does not get reflected out the SIP signaling.

People have mentioned they'd like this (as well as being able to 
passthrough a hold request) but nobody I know of has worked on it.
