If I am reading correctly, this does not lend itself to multi-tenant very nicely. For example, some of my users connect to fs_aa.mydomain.com and others to fs_bb.mydomain.com. Then I can reuse the extension numbers between the 2 clients. However, SRV records, like MX records, are by domain name (ie just mydomain.com). It seems to me that the SRV records for my 2 sample "domains" would evaluate down to the same name and I would lose my critical multi-tenant information. I am hoping that I am misinterpreting the usage of SRV records. If I use SRV and attempt to connect to fs_aa.mydomain.com and the SRV records sort out to sip1.mydomain.com, what does FS see as the "domain name"? If it is still fs_aa.mydomain.com, I LOVE THIS. If it is sip1.mydomain.com, it is going to be cumbersome at the least Thanks for your patients and help, Sean.

My SIP provider offers the ability to route to a second server if the primary is down. That is simple enough, but what about the phones? The desktop devices are not registered with the back FS server. The only idea I have so far would be to change the DNS addresses to the backup upon failure, but that can take a long time to propagate to the phones. How do other people handle this issue?
