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 "alphaxy.callcenctric.com
".

I think you can use asterisk's configuration template syntax to
create the required peer definitions. This would likely look similar
to this (from memory):

[alpha11]
host=alpha11.callcentric.com 

[alpha12]
host=alpha12.callcentric.com 

[callcentric](alpha11,alpha12)
type=peer
context=from-callcentric
defaultuser=1777
secret=
fromuser=1777
fromdomain=callcentric.com 

insecure=port,invite
disallowed_methods=UPDATE
directmedia=no
videosupport=no
disallow=all
allow=ulaw

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.


Many thanks, That worked, I set up 20 contexts for 
alpha[1-20].callcentric.com.

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

asterisk is trying to find a peer based on the _calling number_!

Here's the callcentric peer based on its support pages:

[callcentric]
type=peer
context=from-callcentric
host=callcentric.com
defaultuser=1777
;defaultuser=1914
secret=
fromuser=1777
;fromuser=1914
fromdomain=callcentric.com
;fromdomain=ss.callcentric.com
insecure=port,invite
disallowed_methods=UPDATE
directmedia=no
videosupport=no
disallow=all
allow=ulaw

As you can see I also tried matching to the callcentric telephone number
instead of the id. No luck. The only number I can't match is the calling
number.

Any help appreciated.

sean


Thanks for the response, but no:

# grep -R host * | grep callcentric
exts/callcentric.sip.conf:host=callcentric.com
# grep -R host * | grep 204
#

Why in the world is asterisk trying to match on the FROM header??

sean




Or, more precisely, since this is a peer context, why isn't it matching 
with the ip address 204.11.192.161?


The fqdn callcentric.com has a number of ip addresses:

host callcentric.com
callcentric.com has address 204.11.192.169
callcentric.com has address 204.11.192.170
callcentric.com has address 204.11.192.171
callcentric.com has address 204.11.192.159
callcentric.com has address 204.11.192.160
callcentric.com has address 204.11.192.161
callcentric.com has address 204.11.192.163

Does asterisk only use the first one?

sip show peer callcentric


  * Name   : callcentric
  Description  :
  Secret   : 
  MD5Secret: 
  Remote Secret: 
  Context  : from-callcentric
.
  ToHost   : callcentric.com
  Addr->IP : 204.11.192.171:5080


So do I need 7 contexts, one for each ip address?
