Hello: I have read that music on hold requires a timing source (which I never had to worry about previously since the server had zaptel hardware in it)...now I'm configuring a server in a colo which has no zaptel hardware. If I use the dialplan to run MusicOnHold(), I do get the music upon dialling that extension, but if I try to use the hold button on either a 7960 or X-Lite I get nothing. Is this the expected behavior? I figured that if a timing source was needed that MusicOnHold() should not work, but it does....

I think MOH ?works? without a timing source, but can get end up sounding poor without one. (stuttering, etc) At least that has been my experience. Without a card, ztdummy becomes an option for timing if the box has the correct USB controller to make use of: http://www.voip-info.org/wiki-Asterisk+timer+ztdummy Or you can add a cheap card. We have a box colo'd that I just threw an 8$ card in and works great for MOH, meetme, etc. As for no MOH on hold button pressing, I'd look to your * config for MOH.. -James ________________________________________ From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Marty Mastera Sent: Wednesday, March 02, 2005 2:01 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [Asterisk-Users] Music on hold on timing sources Hello: ?

Updating your installation with the latest CVS code from either stable or head will get MOH working properly again. Sincerely, Trevor Hammonds
There are 2 issues here. Firstly, the timing source you are looking for is
ZTDUMMY. It's in the zaptel source but you may need to edit the Makefile and
uncomment it (remove the # from in front of ztdummy) in order for it to be
compiled and installed. Once you've got it compiled, Just install it as a
regular module in the way you would any other zaptel card module. You need the
timing source for other more important things too, like the meetme (conference
room) functionality.
Secondly, my limited (and possibly incorrect) understanding of MOH tells me that
the hold button on the phone (or softphone) is not enough to engage MOH on
it's own. The hold button generally sends a Re-INVITE with
"a=sendonly" attribute and a zero IP address for media in the SDP
message (This is from the Grandstream user manual). In other words it
deliberately establishes a broken RTP stream between the endpoints.
SOME phones (Sipura, Snom but currently NOT grandstream) allow you to set a MOH
server in their configuration. In this case, you simply create an extension on
your asterisk server that plays MOH, and set this extension number in your
phone's MOH Server parameter. I have this working on the 2 phones that I
mentioned. I don't know if it's supported on the CISCO phone you have.
If anything I've said is wrong, would somebody please enlighten me!

Subject: [Asterisk-Users] Music on hold on timing sources
Hello:
I have =ead that music on hold requires a timing source (which I never had to
worry about =previously since the server had zaptel hardware in it)...now
I'm =onfiguring a server in a colo which has no zaptel hardware.
If I =se the dialplan to run MusicOnHold(), I do get the music upon dialling
that =xtension, but if I try to use the hold button on either a 7960 or X-Lite I
get nothing. Is this the expected behavior? I figured that if a =iming source
was needed that MusicOnHold() should not work, but it does....
Thanks,
Marty
