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       : <Set>
   MD5Secret    : <Not set>
   Remote Secret: <Not set>
   Context      : from-callcentric
.........
   ToHost       : callcentric.com
   Addr->IP     : 204.11.192.171:5080
........

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