Hi, I have been unable to pinpoint a recommendation relating to sizes of fields within the SIP header. The issue relates to how much memory to allocate for each field as a packet is built up.
Section 7.3 of RFC 3261 describes header field formats, but does not discuss length limitations for those fields. Beyond the limitation of the overall packet length, does anyone have a recommendation for how to size the header fields? In other words, is it safe to restrict a Route to 128 bytes, for example? Is there a list of such safe lengths for each header field? If not, what do implementations generally support? Do they generally allow arbitrary lengths of the individual header fields, as long as the total packet length falls within the allowed maximum?
