Re: [OpenSIPStack] Unhandled exception

[Robert V. <ro...@dc...>]

Bill,

Is there any chance I could perhaps mail you my code, so you could tell me 
if I am doing anything horribly wrong?  It's just a form with buttons for 
Initilize, Register, Call, Answer and Hangup (Plus a couple of events, 
allthough I am still getting exceptions when I comment them out)

Regards,
Robert
