PS you can't get out of the media path when you unhold... FS will be
in the media path hold button moving forward unless you use the
uuid_media command to turn it back off.

Hi,

As a newcomer on Freeswitch, first of all thanks you for all your work
on it. I'm currently evaluating it as a replacement for * and really
appreciate working (ok, playing) with it.

One of our requirements is to optimize the network flows as much as
possible, and as such avoid any unnecessary rtp proxying.

When a call is in bypass media and one of the phones puts the call on
hold, the remote phone doesn't play moh.
Of course I guess this is expected in bypass media, and moh should be
the responsibility of the UA just like in a pure sip proxy environment
( so the phone that holds the line should for example invite the moh
server in a new dialog and swap sdp with the remote phone or something
similar).

Snom phones do this just fine when you configure the moh server uri in
the phone, but others like Thomsons ST2030 do not have that setting
(... I know, real crap, but we already deployed tons of them so we
cannot ignore them...) . So when a Thomson puts another phone on hold,
there is no music at all.

I'd like to achieve something similar to what asterisk does with
(re)invites during the hold. I read about and tried the resume-media-
on-hold option and this works fine, the phone correctly gets the moh.
However, when the call is unheld, the media stream continues in media
mode and I'd like to avoid this as much as possible.

Is there a way to return to bypass media mode automatically when the
call is unheld ?
BTW, is the resume-media-on-hold really implemented for server moh
support, or as a more generic way to put a call back in media mode (so
we can listen for inband/rfc dtmf for example) ?

I also noticed that the remote phone only sees/display the hold state
when in bypass media mode. I guess no reinvite (a=sendonly) at all is
sent to the held party when in media mode ? Again, is there a solution
for this ?


Many thanks !

Kind regards

Gaetan

Hi Brian

Thank you. Indeed I'm using those options. My question was really
about getting out of the media path on unhold.

NB, sorry for the double post, I didn't realize the list was moderated.
