If you can notify, you can call.  This fixes nothing other than refreshing
NAT if that's involved.

I have a feeling that some people in this discussion have a lack of
understanding about the SIP protocol and the underlying networking that
could affect it.  The original post failed to say whether this was on a LAN
without routing, on a LAN with routing, or a WAN.  Each of those could
result in totally different results and solutions.
