Conference Call Providers

I have 2 line my 2nd is for the fax machine, but we had recorded conference calls before dsl and it was working. I do take out the telephone line frm fax and connected to my recorder. But all I hear is statics.I have tried to change spliters,all line have a dsl filter! Can someone help me before I call somebody!!!!

I think you just press *7 to talk and then *6 to leave, but I’m not sure. I’m going to be listening to one in a half hour. Thanks!

I have a Panasonic KX-TG5631 and Vonage phone service. I am able to connect 2 other caller into conference mode however the catch is that I have to call them

I have a cell phone with Sprint which allows me to connect both incoming and outgoing calls into conference mode.

Does anybody know of any phone that would allow me to connect outgoing/incoming calls into a conference?

I would have several uses for the use like this and it would be really helpful as I run a business and I do conference calls several times a day. Anybody know if this is possible with a cordless phone similiar to the Panasonic we are using, or does the change need to be from our service provider to allow incoming/outgoing calls to conference?

We’d like to set up teleconferences where (for example) we have six groups of four people on the phone. In the “small group” setting when each person talks they only hear people in their small group. When we switch to “large group” then everyone can hear each other.

We could do it by patching together different sets of conference calls, but I’m wondering if there is a service that has these features. I’m imagining a web interface where we can group and ungroup people.

There are other features we’d want (hit a certain code to dial the leader of the call from the small group for example). There are a lot of teleconference companies out there … who has the most advanced features in this area?
