Internet Calling refers to a capability you may or may not need.  Most
people make phone calls with phone numbers, but in SIP you can also use
a SIP URL, which looks like an email address: sip:u...@example.com 
If your system is not directly on the Internet (most are not), then
routing a call to an arbitrary domain name requires that it go through
an SBC.  This routing to the SBC is _all_ that the Internet Calling
does.  If you decide to enable this capability, you can use the same
sipXbridge instance for this that you use for the connection to your
ITSP.

Since you appear to be the first person to try using Flowroute with
sipXecs (if someone else out there has done this, please speak up),
you'll have a little pioneering to do.   If you follow the directions on
that wiki page carefully one step at a time, you should be able to get
it working.

If you're not sure what to do with a setting, leave it at the default or
stop and ask on this list.

You do _not_ need to change any settings on your phones - leave them
alone and they should continue to work.
