From: Hume Vance <[EMAIL PROTECTED]> Is there a list of such safe lengths for each header field?
No. 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? sipX allows fields and SIP messages to have unlimited length. Our experience has been that devices that set limits set them too low. Recently, we discovered that a popular SIP/PSTN gateway product can only process seven Via headers on a request. As a result, a particular call-forwaring pattern in the PBX of our customer failed. We expect such failures to become more fequent as we start to use SIP between organizations. The Pingtel interoperability server (http://interop.pingtel.com) lets you test that your UA isn't confused by long messages.
