Projects to get VOIP and SIP development experience
Hi All,
I want to get some hands-on VOIP and SIP software development experience by doing some personal projects at home. I'm wondering if any body can recommend a good place to start from: books, web-sites etc. Where can I get trial/educational versions of commercial VOIP and SIP protocol stacks? Is there any popular open-source protocol stack?
I'd appreciate your comments and suggestions.
John
