Meet-Me Conferencing

Host codes and music while waiting with meet-me conference. Single vector solution. by dufus2506
Posted: 2 Jun 09 (Edited 17 Mar 10)

Meet-me with a host code.  Works for 6-party and EMMC.

Tested on version 5.1.  Should work with any system that has VDN variables.  (Basically 3.1 and up.)

Essentially, I'm making use of vdn variable V1 as the host code.  Build a standard meet-me vdn, and add a host code in the field of V1.

Unlike other methods described, this one doesn't need to reset a variable.  Once the conference ends, and everyone disconnects, callers can't restart the conference without a host dialing in as well.

I set the host code to be 4 digits, but it can be as many as 16.  

As the host, you don't acquire any special "host" features.  You can't "mute all participants" or anything similar.  The host ID is only used to start the call.  For call control of the conference, check out the conf-dsp, drop, and fe-mute station buttons.  The host can disconnect without ending the conference.  

Callers connect directly if the conference is already in progress (host has connected) but will wait hearing music until the host arrives.  Within 5 seconds of the host's arrival, all waiting callers are connected.

If the host does not arrive callers will wait indefinitely.  (Sorry, but you can't set variables in meet-me conference vectors, so you can't limit the time.)

You can use this vector as a common vector for all of your meet-me conference vdns.  You don't need to have a different vector for each meet-me vdn.


You can leave off the passcode, (and the passcode checking steps 1-6 below) and just use the meet-me vdn, and the host code.  I left it in so users can change the passcode if they need to.  (To keep any particular conference call private.)

You can increase the "collect digits" in lines 2,4, 27, and 29 to 10 instead of 6 and 4.  Then record the associated announcements to say "...followed by the pound sign."  Most people will expect to enter a # at the end of the passcode and host code anyway.  This will keep system hackers from knowing the length of the codes you use, and will probably be a more familiar way of entering digits by users.

If you don't want to use a common access line, route all vdns to the main conference bridge vector.  Record the announcement described as 4640 below to have a system greeting.  (i.e.  You have reached the conference bridge, please enter your conference passcode.)  You'll need to use DID numbers as meet-me vdns.
