Conference calls

I Found a good way of allowing external callers to dial in to an OXE/4400 and enter a code to enter a conference (without operator or internal user intervention). This works like the 'my teamwork' but without the OTUC.

Also, can be set to disconnect conference if only external callers are present after a timout.

It is not very difficult, you need DISA license etc..

Let me know if anyone is interested

Meetme conference?
The 29 one?

Which? Substitution?

Or something new? Will be cool a trick

If you have to use disa, well.. You call in, and you dial the conference code ?
Does your system works for people who are not in the DISA list ? And if is, once the conference is finished, do you have to change the DISA code so they cannot dial in anymore ?

You can dial meet-me prefix after DISA call but only after substitution (manual or automatic). This used for people from company (not for all) becouse you must give user number and set password for this (or manage speed dialling for automatic substitution).

The only way I know to allow people from outside get in, without disa, and without otuc, and without being transfer, is to loop a T1..

Sorry - I should have clarified - 29 party.

The principle was to allow external callers (unknown CLI) to dial in and just enter a code. I automatically substituted the caller for a fictitive user who was in a PNC with no outgoing call rights.

Then the code they dialled simply consisted of:
meetme prefix + conference code. (shortest code could be 2 digits - longest cold be very long

).

In terms of perception, this works in much the same way as the public/commercial conference services. The user obviously needs to know the code to use.

I know it sounds obvious but many customers complain when they want to set up conf and they have to call the participants in - rather than the participants coming in by themselves.

Best Regards

If you want to allow for external user dial meet-me prefix for conference - from my poin of view you have one possibility - create speed dialling without barring (f.e. 1234) where call number will be what you want (f.e. meet-me prefix+password or substitution+number+password+meet-me+password). User call DISA number and dial 1234 (f.e.) and PBX will dial whate really necessary.

knightr1der,

I think with your solution, a user could enter the meet-me conference prefix, and enter his own conference code, which is no good..

Frank,

If he did enter his own code, he would be on his own!

The idea is that the DISA number is not a public service number. It would only be given to 'invited guests'. If any abuse is a concern, the the DISA service could always be renumbered.

There is a similarity to the 'public service' conference facility - if you are invited to one, you will be given the 'password or code' to dial after connection to the provider.

Frank, are we missing each others point?

No, I understand.
This is one of the 2 solutions so an external user can get into a 29 party conference without being tranfered.. Disa or T1 Loop.

But with your solution, once the number is known, the user can come back and have its own conference with someone else.. So no good for me ..

In your solution, you would have to change the DISA code every time a conference is done, so people cannot get back into DISA. Also, allowing DISA with a code is bad if you have the bad code threshold turned on. If you face a war-dialer (like i used to be when i was a kiddy), he'll try all codes. After so many codes, your DISA will be locked.

I wrote a modem application a long time ago (under windows NT4). And I was able to pickup call, record voice, play voice, and do actions on the call depending on the DTMF received.

A good idea would be to develop an application like this one, where you could setup a computer with a modem, and an analog line. People call, enter the conference password, and get transfered in. You could be able to program this PC remotely to allow conference from whenever to whenever. I am developping another application now for the file repository, but I'll work on this one later, maybe, lol..
