What is the limit on the number of proxies servers that can be designated in the “Proxy:” field?

Eddie,

This is done using DNS using either SVR or A record as follows:

For SRV Record:
sip.server.com:SRV=node1.sip.server.com:5060:p=1:w=5
0|node2.sip.server.com:5060:p=2:w=50
NOTE Set "Use DNS SRV" to no and "DNS SRV Auto
Prefix" to no.

For A Record:
sip.server.com:A=172.20.2.1,172.20.2.2
NOTE Set "Use DNS SRV" to no and "DNS SRV Auto
Prefix" to no.

Creating these DNS records will enable you to in effect have numtiple SIP Proxy.

Please consult the Admin Guide where it explains this in more detail:

The question is whether there is a limit to the number of servers that can be defined.

There was none stated w/in the docs, so your guess is as good as any, unless you find someone who has came upon this limit through testing.
