[asterisk-users] multiple host= in sip.conf

[Bryan Laird]

for inbound connections how does asterisk manage host=host-name  
returning multiple A records... will
it allow authentication for any of the IP's returned?

I would assume that in the case of 'inbound' if you specify a host- 
name that you have PTR records for you could do it in one entry
again I'm making a blind assumption.

IE say you 10.23.23.3, .4, .5 as his IP's
if you created entries either in your own dns or etc hosts (depending  
on os) you should be able to create entries
for each of his IP's all resolving to the same name... and then "one  
entry" ... for his transactions from him -> you.
now the reverse of you -> him you would in theory loose control over  
which host you send the call to but if he doesn't
care then it wold work...

and while this assumes you have no moral / security objection to  
using host-names.

someone would have to keep my honest here though as I haven't looked  
at where asterisk does the NS lookup and how those transactions work.
if it only read the conf file and did a translation at startup via a  
single lookup for host name then this  wouldn't work.
