Ok, this is probably an easy question:
Say I have my kamailio server set up and all of my voip clients are gleefully calling each other... but now I want to connect them to the PSTN.

Can I set up kamailo to trunk calls using a few grandstream gateways? or is Asterisk neccesary?

If you have a gateway device you can configure Kamailio to forward the calls (which are designated to the PSTN) to the gateway. Basically it doesn't matter if the gateway is a high end Cisco/Audiocodes gateway, medium priced Grandstream gateway, or just an ATA with FXO interface.


Sorry if the answers out there, but I haven't found anything that answered the question directly. I'm a linux admin, but I'm new to PBX's and the like. I've installed kamailio in the past using instructions specific to that situation, but haven't configured trunking (or I didn't recognize thats what it was)

references to howtos or tutorials would also be greatly appreciated

The idea is rather simple: before doing lookup() you analyze the userpart of the request URI. If it is in a certain format, e.g. only digits with an optional leading + sign, the instead of doing lookup() you just forward the request to the gateway.
