Use [EMAIL PROTECTED] for questions on current sip


There is no "maximum" size for SIP headers. I have seen examples that far
exceed the sizes listed below. Any SIP implementation really needs to be
able to handle headers of arbitrary lengths. Fixed length buffers for this
data is not a wise approach.

If you are looking for "typical" messages, I suggest you look at:
