Make call to device on PSTN #69

Closed phrohdoh closed 7 years ago

phrohdoh commented 7 years ago

How would this be done?

I cannot use the MakeCall command with +1<tel-number> because the + throws off the command parsing so this leads me to believe I am headed down the wrong trail entirely.

You'd need a PSTN gateway: http://meetings.ripe.net/ripe-46/presentations/ripe46-eof-enum-sip-pstn.pdf

UPD: Mind, that you can still address a PSTN number within sip scheme, although you'd have to put it into the proxy domain, like in example here: https://www.tutorialspoint.com/session_initiation_protocol/session_initiation_protocol_to_pstn.htm

The issue I'm having (being completely new to the telephony world) is that I have no idea what domain should be used for what number.

So my plan is to use Asterisk as the gateway.

Asterisk can be used to build a gateway using a standard computer and one or more telephony interface cards.

If I can get that working would I be able to use pjsip4net as the "softphone" or would I no longer need to use this project?

Thanks for your help so far! :-)

The domain in the simplest case could be your Asterisk's IP address, although it depends very much on your setup, and yes, you can use pjsip4net to build a softphone calling to PSTN via a proxy for sure.
