[SIPForum-discussion] SIP testing: big SIP message

[Kerry]

Eugene Mednikov，您好！ 

　　a message with a lot of Contacts is a good choice. 
      as per rfc3261, if a sip account is registered by multiple endpoints, there are many contacts in database for this account, and the ok message will contain all of the contacts , which results in a
       really large sip message

Greetings!

RFC 3261. 18.1.1 Sending Requests

   If a request is within 200 bytes of the path MTU, or if it is larger
   than 1300 bytes and the path MTU is unknown, the request MUST be sent
   using an RFC 2914 [43] congestion controlled transport protocol, such
   as TCP. If this causes a change in the transport protocol from the
   one indicated in the top Via, the value in the top Via MUST be
   changed.  This prevents fragmentation of messages over UDP and
   provides congestion control for larger messages.  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.

    How do I create message of length 65535 bytes? Huge SDP I assume. But I don't know length of message before SDP in advance. Is there any way to overcome that?

Respectfully yours, Eugene Mednikov.
