Thanks All for pointing me towards some resources. I have never written any protocol stacks before except for few small SIP tools. This would be my first time writing a SIP stack and that's where I felt a need for some literature or books on designing protocol stacks. Anyways, if I run into something I will definitely let you guys now.
