asterisk users - Nov 2007 - sip proxy failover

Hi,

Is it possible to failover from Outbound SIP proxyA to Outbound SIP
ProxyB on the event that Outbound Sip Proxy A became unavailable - using
the qualify option for sip peers - it should be possible to monitor the
ping/back time, which would give us a good indication of whether a host
is up and running.

I have had a look in the mailing list archives, but cant see this having
been asked before?

How would someone do this in Asterisk - would this have to be done with
Dialplan programming, before placing the call, it would check the most
recent qualify ping time and route based on that?

As far as I am aware it is only possible to put host=xxx.xxx.com once in
sip.conf

Has anyone got this to work, to have a failover outbound proxy in
asterisk, which automatically fails over?

Thanks :-)

You can use DNS SRV records to specify more than one proxy and their order of
usage.
