Thanks; I have made some progress on my config, but now I have an issue sending the calls to the gateways. I took a config file from "Building a telephony system with openser" from Flavio E. Goncalves an adapted it to my needs, but when I try to pass a call to PSTN I receive error 404, not found.

This is the debug of the call:

Any Idea why calls are getting rejected?

        Thanks.....

        

Could somebody share a simple config file using dispatcher module.

        

Thanks

http://www.dialogic.com/products/docs/appnotes/10833_HMP_OpenSER_SIP_an.pdf
is the most concise example i've ever seen on using dispatcher, should
be enough to get you going. A zip file is linked in the pdf that with a
sample config
