Thanks Jan - I'd read Andrew's article and it was interesting, despite the 
IP address typos in the configs, but didn't quite apply to our situation 
as we were looking for active-active and Windows, so I was hoping for 
something a little nearer to give me some confidence.

Regards,

Dave

Hi David,

the basic idea of load sharing with alternate gatekeepers works without
round-robin DNS (but it could be combined for redundancy, see below).

AlternateGKs heavily relies on a setup, where endpoint actively
register with their gatekeeper. This might be the case in your
video-conferencing setup, but for it isn't for many call termination /
call routing setups that work mostly with untegistered gateways.

Andrew Olson wrote a detailed description how to set up an
active/passive configuration with IP failover on FreeBSD:
https://rdweb.cns.vt.edu/~anolson/gnugk_vrrp.html

But to be honest, I wouldn't try to set this up, if I couldn't test the
configuration in a lab. These configurations can get complicated very
easily.

Regards,
Jan
