[asterisk-users] Music On Hold Between Servers

[Douglas Garstang]

Can someone tell me how Asterisk handles music-on-hold between servers?
Documentation for this is non-existent.

Lets say user A, who is registered on pbx1, calls user B, who is registered on pbx2.

1. User A puts user B on hold. The moh that is played to user B should be specified according to user A. Which pbx box should this be set on? pbx1? pbx2? Both?

2. Is the situation any different if the 'trunk' between pbx1 and pbx2 is SIP or IAX?

Thanks,
Doug.
