I have been recently playing with AsterixNow and got a nice network set-up with trunks and sips. Outgoing calls go to a VoIP provider that charge me say 2pence per minute for local mobile. I have been looking and trying to research how VoIP providers connect to the rest of the worlds networks, eg in UK British Telecom.I read up that they use MDE's that connect in tandem to other networks.. fair enough.. How does VoIP providers connect to BT
As in UK Calling BT landlines is free and many EU based VoIP providers offer UK landlines free.. but also offer free landlines calls to tens of other countries(in which the biggest telecom don't offer free land line calls to any customer)
If I would like to offer my own VoIP service how would I plug directly into "a network"?
I know allot of places offer reseller options and affiliate. but I am not interested in that.
Does anybody know or have experience with this sort of thing?
