Yes, if what you call a "context" is your peer definition in sip.conf. CC
routes calls through a varying number of SBCs, all (also) resolving to
callcentric.com, but each having their own name, typically "
I think you can use asterisk's configuration template syntax to create the
required peer definitions. This would likely look similar to this (from
Add templates for all IPs that callcentric.com returns. Note that this
approach isn't foolproof: if/when CC change their pool of SBCs, you may
have to add more hosts, or remove them from this config. And, as you say, I
believe the cause is that asterisk only uses the first returned IP for a
host name. (Interestingly, the DNS server authoritative for CC also varies
the order of IPs it returns. Guess that's their way load-balancing.)
And again, the above is from memory. I can look it up later today and will
follow up if I goofed/misremembered.
