...yes, I'll admit that is an easy way out. But we still need to handle
conversion to ISO8859-1 caller ID's and find a way to do pattern 
matching and how to use "." and "@" in IAX to call SIP uri's - there are 
many things to consider. (The @ in an IAX2 dialstring separates 
extension from context...)
