I'm looking for tutorial or docs on how to establish a connection to an external SIP provider and info on routing calls to the provider based on number dialed (I assume using a dialplan of some sort?). Also, where do I get info on taking inbound calls from the provider and sending out to certain registered extensions?
Links to doc or tutorials would be perfect. Sample code or any help is greatly appreciated.
your questions are a bit too generic, so difficult to answer - if you can be more specific on what you try to achieve, it will be great .
