Summary:                    Large SIP messages are truncated to 4096 bytes
Description: 
According to RFC 3261, SIP implementations MUST be able to handle messages
up
to 65535 bytes.
Asterisk currently can't handle SIP messages larger than 4096 bytes
excluding IP and UDP headers. Larger messages are truncated.

RFC 3261, Section 18.1.1 Sending Requests

   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.
