Hmm, it's now yet completely clear to me how your actual setup looks
like. Why do you use 

if_inbound  = eth1
if_outbound = eth1

? Do you really have your local UA's *and* the conenction to the outside
world on the same interface (logical AND physical)?
I understand you in a way that the interface eth0 owns the IP address
192.168.0.1, so this IP is NOT seen as an "own" IP for siproxd, as the
eth0 interface is not mentioned in its configuration. So make sure your
internal UAs do use the proper internal IP address (the one where the
if_inbound points to).

If you plan to deal with multiple internal subnets (without routing in
between them) then you need a siproxd instance for each subnet (put them
on different UDP ports, e.g 5060, 5062).

However, I still would like to get a debug log file (debuglevel=-1) of
such an event. As I understood you correctly, your siproxd machine uses
192.111.200.139 on eth1 and 192.168.0.1 on eth0. So it is not clear why
both IPs are involved...


And yes, siproxd requires a DNS environment that is working. It is not
the only component on a SIP network that relies on it. If the DNS from
your provider / SIP registrar is not that reliable, you could:

- introduce a caching nameserver for your local network
- use the plain IP address in siproxd config file
