Summary:                    DNS host name resolution in iax.conf
Description: 
I defined host=voipb1.mydomain.local in a iax.conf trunk and it was working
fine until the DNS A record of that host changed IP address. Asterisk still
tried to send calls to the old IP address.
I restarted Asterisk and the calls were finally sent to the correct IP
address so I'm guessing that the "host=" name resolution is done only at
startup.  

iax.conf:

[coin]
deny=all
allow=alaw
allow=gsm
type=friend
host=voipb1.mydomain.local
secret=xxx
auth=plaintext
qualify=yes
context=coin-context

I'm using:

# cat dnsmgr.conf
[general]
enable=yes
refreshinterval=60

*CLI> dnsmgr status
DNS Manager: enabled
Refresh Interval: 60 seconds
Number of entries: 2

Does the DNS manager work with the /etc/hosts file?
I tried changing the IP address within /etc/hosts and waited more than 60
seconds (failed).

I'm using djbdns in my network so I tested it with a record A with
TTL=5min. I changed the IP address in tinydns and waited 6 minutes. A ping
to the host name resolved the new address fine. However, Asterisk will
still send the call to the old IP address, unless I restart the * process.

How can I "debug" dnsmgr in Asterisk? Could I actually "see" the 2 entries
that "dnsmgr status" reports, thus confirming that it is not updating
correctly?
