[Serusers] sdp and rtp errors

[Paul Hazlett]

!= means "not equal"

! by itself means the inverse of the result, like in C, where !TRUE ==
FALSE and !FALSE == TRUE

I'd recommend you get that Getting Started document from www.onsip.org
if you new to SER because it is a rather complex project.

Regards,
Paul
