[asterisk-users] Remote hold on PRI

[Gaëtan Minet]

Hi Shane

yes, with verbose activated, I get something like this:

starting Music on hold for Channel SIP/XXX (the local caller sip side)  
with the class specified in sip.conf.

With zap span debugging enabled, I see the bridged zap channel  
receives "REMOTE HOLD" notification just before the moh starts.

That sounds like a nice feature between enterprise servers, but not so  
good between different companies of course.

I wonder if this is not a side effect of the (relatively new ?)  
"mohinterpret=passtrough" option. That would be nice to have a  
"mohinterpret=disable"  in fact:).

Thank you

Regards,
Gaetan
