You can still send REQUEST larger than 1300 bytes. If you read in the same section it says
However, implementations MUST be able to handle messages up to the maximum datagram packet size. For UDP, this size is 65,535 bytes, including IP and UDP headers. Refer to Section 19.1.4. it says the two URIs are different. sip:[EMAIL PROTECTED] (can resolve to different transports) sip:[EMAIL PROTECTED];transport=udp Thanks, Neel -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tai-Hsing Yu Sent: Sunday, February 20, 2005 7:53 PM To: [email protected] Subject: [Sip-implementors] Questions of large request message Hello, I have some questions about handling SIP msgs that are larger than 1300 bytes. RFC 3261, chapter 18 as listed, mentions that if request message is larger than 1300 bytes, it MUST be sent using TCP because of the meesage size constraints. But what should the proxy do when user registers to Proxy/Registrar with "transport=udp" or without "transport" parameter?? Any acknowledgement will be deeply appreciated.
