Hi,
I'm a novice trying out an experiment with Asterisk
and was unsure of the hardware needs for it.
I'm wondering if its possible to receive a call from
an external number (PSTN) say A. Then make a call to
another external number (PSTN) say B - and then bridge
the two calls so that A is talking to B? What hardware
will I need to be able to do this.
Secondly, if I had x number of simultaneous calls (A
talking to B) - how many PSTN lines would I need? I
think 2x.
I know this sounds ridiculously inefficient - but I
think the experiment might open some avenues.
Thanks,
Doug

The hardware will depend on what interface you will be using to the outside world. IP (SIP)? POTS? DID/DOD trunks over T1?> Secondly, if I had x number of simultaneous calls (A > talking to B) - how many PSTN lines would I need? I > think 2x.That is correct. Don Pobanz

You'd need FXO ports to connect Asterisk to analog phone *lines*, and FXS ports to connect Asterisk to analog *phones*. You could also use IP phones, and/or a VoIP provider.> Secondly, if I had x number of simultaneous calls (A > talking to B) - how many PSTN lines would I need?

Again, you could use a VoIP provider to get around the hardware costs of analog ports if port cost is a concern to you. -Jared
