This is something we've asked Audiocodes to build into the SAS feature in their gateways. Technically it's called Call Admission Control. We feel it's best addressed at the network infrastructure level (the routers know best their own load and their routes) but realize that most network equipment isn't ready to do this.
If this can be done as part of SAS, the remote phones are all pointing to the remote gateway as an outbound proxy. The outbound proxy should know all the calls going through it. Unless you folks have a better suggestion or would like to write something and contribute it back...
