[reSIProcate] Gruu and ClientRegistration

[Byron Campen <bcampen@xxxxxxxxxxxx>]

	I've been looking into the Gruu code a little more, and I have a  
couple questions related to how ClientRegistration uses it. The first  
is the interaction with the old r-instance code; we are still  
determining which contacts are ours solely by using r-instance;  
shouldn't we be using +sip.instance if it is present?

*snip*
try
{
   if(it->exists(p_expires))
   {
      // rinstace parameter is added to contacts created by this  
client, so we can
      // use it to determine which contacts in the 200 response are  
ours.  This
      // should eventually be replaced by gruu stuff.
      if (it->uri().exists(p_rinstance) &&
          it->uri().param(p_rinstance) == itMy- 
>uri().param(p_rinstance))
      {
         expiry = resipMin((UInt32)it->param(p_expires), expiry);
      }
      else
      {
         fallbackExpiry = resipMin((UInt32)it->param(p_expires),  
fallbackExpiry);
      }
   }
}
catch(ParseException& e)
{
   DebugLog(<< "Ignoring unparsable contact in REG/200: " << e);
}
*snip*

Also, when addBinding() is called, we don't do anything related to  
+sip.instance; is this the intended behavior?

Best regards,
