Benny, thank you for the response. Python is not my language of choice or background. C just so happens to be. If it turns out to be 400 LoC so be it. All good programmers are lazy programmers and look to reuse. If nothing exists to draw on I'll give it a go on my own. Or consider using a sister asterisk system and the AGI interface for outbound calls in language of my choice. PJSIP just sounded appealing because I could write a stand alone app and place it anywhere to test w/o configuring an entire PBX. Thanks again.
