SIP in higher education

There are a few proxy settings: Backup Proxy, Emergency Proxy, and some 
others.  I don't know how well this works for automatic backup, but it 
would be worth a test.

In the SIPDefault.cnf, SIP<mac>.cnf files you can add proxy_backup, 
proxy_emergency, etc.  Or you can hardcode on the phone itself.
