Has anyone successfully had a SIP phone fail over from Asterisk Server A to Server B using DNS SRV?
If so, which phone worked for you? I'm assuming you set up your DNS SRV records

servers have equal priority and equal weight.
In order to make calls through B after A goes down, do you have to wait as long

Thanks for any help. We've been trying this with Aastra 480i phones and SJ Phone without much luck so far.
I do this with SIPura. I tell the box to use DNS SRV records. The
first record points to the internal IP of my asterisk server (for use
when I am at the home/office). The second one points to the external IP
of my router that has port forwarding. I can roam pretty much anywhere
without any reconfiguration.
