Dear All

Good Day,

While Studying SIP protocal, Stuck at FROM-TAG usage.
TO-TAG usage is clearly explained in RFC2543. But FROM -TAG usage is
written in 2lines.
Can you please elaborate for understanding.


If the From address can appear
   in requests generated by other user agent clients for the same call,
   the caller MUST insert the tag parameter in the From field.
