Micheal: Thanks. Setting a static IP for NAT brought everything back up. Luckily, my external IP is "dynamic", but it hasn't changed in nearly 6 months.
So, it looks like I have a stale/cached A or CNAME record for stun.ezuce.com?

If at all possible, always set this NAT setting to static and enter your external IP.

No update or changes have been made to the sipxecs 4.4 server for days, nor has any networking details changed within my LAN. ping and traceroute seem to indicate the issue is with stun.ezuce.com . Could this be related to hurricane Irene? Is anyone else noticing the same problem?
