[SIP Beyond VoIP] Robustness of Sylk-Server

[venu Y]

Hi Anil,

Here is the sample flow from RFC 4975.
For initial dummy send

Byte-Range should be 1-0/0
To-Path and From-Path should be extracted from SIP signalling.

MSRP d93kswow SEND
To-Path: msrp://bob.example.com:8888/9di4eae923wzd;tcp
From-Path: msrp://alicepc.example.com:7777/iau39soe2843z;tcp
Message-ID: 12339sdqwer
Byte-Range: 1-16/16
-------d93kswow$
