Im supposed to use SIP for my application. I went through some documentation regarding SIP like ietf-sip-documentation , siphon , linphone for iphone and ipod. But nowhere they have mentioned about any available frameworks or any such a thing for implementation part. There are lot of things that are yet unsettling to me about SIP. I would love to get a little more clarity on this. Any help would be appreciated.
EDIT: I would want to know whether there are any frameworks available for ios or should we create our own classes for the interface?
Thanks
Doubango framework http://doubango.org/ / https://code.google.com/p/doubango/ also does a nice job here. C-based, so you would probably like to do your own Objective-C wrappers.
