[SR-Users] Rewrite BYE to Cancel

[Steve Davies]

Hi,

I'm normally a bystander.  But on this occasion I've got to comment - there
are broken SIP implementations, and there are BROKEN ones.  Surely there is
no hope with this one?  If they can't get this right just imagine how many
more problems it will have.
