You are correct, I'm not using the BYOD server. I'm using their primary SIP server in Dallas (sip-central01.voipwelcome.com). There are a few users around including myself who were given their primary SIP credentials before Voipo stopped supporting BYOD. Unfortunately, you are stuck using the BYOD server since they no longer give out primary SIP credentials.
As Tim stated in the thread below, I don't believe STUN is needed for most users, but it never hurts to try. I'm not using it myself and don't seem to have any NAT related issues.

A quick Google search indicates calls dropping after 30 seconds with ACK issues is likely due to NAT problems or a firewall blocking ports. I'm not sure of your network topology, but I'd try STUN first, if that doesn't work you might want to try bridging your DSL or cable modem and let the router directly handle DHCP or PPPOE. This will ensure a single NAT to your BYOD and should eliminate any firewall blocking in the modem. In your router, you might want to forward UDP ports 5000-65000 to your BYOD's IP address.
