Summary:                    Incoming REMOTE_HOLD on Zap is always passed to the
bridged channel
Description: 
We have several customers using PRI E1 lines to connect to the telco
(Digium TE220B cards, E1 PRIs in Belgium).

When someone on ther side calls out using a SIP phone another party
through the telco/pri and gets placed on hold by the remote party, he hears
the local music on hold and not the remote music on hold. That's confusing
our customers as often the company name and products are often said on top
of the music.
In fact he can briefly hear the remote moh that gets replaced after half a
second by the local one.

This happens when the remote party is using a PBX on PRI, some PBX on BRI,
and also mobile phones.

In the logs I see the zap channel is receiving a REMOTE_HOLD control frame
and the the local moh is started on the bridged sip channel.
