I'm finding that my Asterisk server is bombarding my DNS servers with
lookups like the following:

Queries
5060-b7bfce38: type A, class IN
Name: 5060-b7bfce38
Type: A (Host address)
Class: IN (0x0001)

One call alone has a handful of requests to our server, simply looking
for an A record for something like '5060-b7bfce38' (listed above). The
DNS server immediately responds with "No such name".

I use only SIP on my box, and even if I just have the call go to hangup
it does this.

My SIP.conf contains 'srvlookup=no' in the general section.

Any thoughts or suggestions?

Best regards,

Mik

I have seen that before. If I remember correctly, the solution was to
put the IP Address of the Box in the /etc/hosts file.
Like for example:
192.168.2.1 asterisk.localhost

If you have multiple interfaces with private IP addresses then put them
all in the file.
