Two or more UAs on two or more separate machines must register with two or more Registrars on 2 or more separate machines, to provision a hot-failover capability (meaning so long as 1 registrar and 1 UA are functional, the call will go through) The two or more UAs are the same entity to callers. (sip:Joe at Blow.com:5060 is the only number they dial) Are there hints in documents how to do this? So far I've found similar, but not similar-enough questions and answers, and a ton of hits on how to configure your CISCO box. Clues and comments greatly appreciated. -------------- next part -------------- An HTML attachment was scrubbed...
