Where can you set a tertiary server?  Its only primary and secondary -
unless you are talking about using DNS-SRV, in which case you can add as
many as you like.

However, this is not entirely true.  According to Polycom, the phone will
*not* send another registration request to the secondary phone in the event
you pick up the phone and make a call and the primary server has failed.  It
will only make the call but not register with it.  The phone will only
re-register when the registartion expires.  According to Polycom and
Asterisk/Digium, set the expiration to 1 minute and for th emost part you
should be "ok".
