# SIP typically uses port 5060.
|
|
#
|
|
# This pattern is based on SIP request format as per RFC 3261. I'm not
|
|
# sure about the version part. The RFC doesn't say anything about it, so
|
|
# I have allowed version ranging from 0.x to 2.x.

#Request-Line = Method SP Request-URI SP SIP-Version CRLF
