Hi, I'm an absolute newbie and wanted to know the following. I want to have a setup where I have a PSTN line connected to my Asterisk box and want to know if it is possible to make more than one simultaneous outbound call through that VoIP gateway? Can Asterisk do this magic of concurrent calls on one PSTN line?? If I put it in other words then can I receive more than one simultaneous call on a PSTN number through Asterisk (the dialplan would forward those calls to different extensions) and the phone line still be able to receive more calls? Do I need some special hardware for the above or a simple SIPURA3000 would be good enough? Please pardon me if this is not the correct list for this question. Thanks. Best Regards, Hitesh

The long answer is that Asterisk (and, indeed, any other PBX) is not be able to make or receive any more analogue calls than the number of available analogue trunks (or lines) to which it has access. You may, however, use an ITSP to send outbound calls over the Internet, leaving your analogue line free for an incoming call. You may also be able to subscribe to Busy Call Forwarding on your POTS line. This way, when your analogue line is in use, additional inbound calls may be forwarded to a DID (telephone number) provided by an ITSP -- essentially increasing the number of "lines" available to Asterisk.

I was thinking if a GSM to VoIP gateway can do the job of multiple outgoing calls. I could be wrong but seems like cellphones do allow you to make multiple calls at a time (only one is active or one active conference). If we assume that I have a layer on my Nokia phone which allows me to have more than one active call then when my Asterisk system tries to make a call through the GSM-VoIP gateway then it would never get a busy and the layer on phone would do the job of facilitating calls. Is this a possibility that anyone has tried? Thanks. Best Regards, Hitesh

Or the more interesting facilities available on the 3G (and beyond) networks? regards, PaulH
Sadly, at the end of the day the answers will probably be no, no, no and no.
