I have many years of experience in Linux and Computer Networking but I am not very familiar with Telephony concepts. Can someone explain simply or provide and example how a VOIP (SIP) call can be connected to an outside line (Cell Phone, Home Phone, etc.)
I have a program on my computer that can call IP addresses using SIP, but how do I call phone numbers (I.E. 111-222-3333) with asterisk?
Any help would be greatly appreciated.
