I'm trying to create a VOIP system that will allow me to run multiple conference calls at the one time.
For instance, A is talking to B and C And at the same time D is talking to E and F
So I'm guessing that would require to phone lines to accomplish?
I want to do this with no other hardware than a home computer and an internet connection. Which is why I mentioned SIP. From what I've gathered, I would simply install Asterisk and create a VOIP account with some provider then point Asterisk to that provider's SIP server?
All the forum posts I've read on this matter have people saying they've got that setup working perfectly. But I foresee a problem with multiple phone lines...
'Skype for SIP Beta' give you the ability to pay for multiple 'channels' allowing more than one phone conversation at the one time. Which is what I want. But lets say I want to use another VOIP provider. All the VOIP provider's signup pages I've looked at don't mention anything about multiple channels/lines. You simply sign up and that's you done.
Does this mean their one SIP account you sign up for will give you multiple lines? Does Asterisk handle all this routing? Do I need to signup for multiple SIP accounts and point Asterisk to each one to replicate the multiple lines?
To sumamrise what I need: A system that will let me make multiple concurrent VOIP conference calls
How can I get this working?
EDIT: I don't intend to have any 'internal clients'. All Asterisk will be doing is receiving two phone numbers (landlines) and then calling them both to create a three way conference call. The two landline numbers can be anywhere in the country. They won't be on any internal network.
To put it into ASCII
Landline1 ---- Landline2 \ / \--/ Asterisk
Hope that clears it up
