No, I am not seeing any options messages. It doesn't appear to be doing anything while in probing mode. How often should an OPTIONS message go out? One thing to note, i have two public IP addresses on eht0, so I have eht0 and eth0:1. I also have eth1 which is a private network interface. I have nothing specified in the kamailio.cfg "listen", so Kamailio just listens on all IP addresses. I do not believe this happened before I added the 2nd IP to eth0. At that time, i also had explicit listen parameters specifying the internal and external IP addreses. When the configuration was in it's previous state, this never happened. One additional bit of info, the servers that are in "P" state are on a different public subnet. The servers in "A" state are all in the same public subnet as the Kamailio.

So why would not having any listen= parameters cause this to become a problem? I am guessing that is the problem... Also, I am a little concerned about the mhomed parameter, specifically this statement: "By default is off (0) - it is rather time consuming."

Also, why wouldn't Kamailio just be forwarding the request on the socket which received the incoming request? That would work fine as it's being received on the public IP and I want the forwarding to be sent on the public IP.

Well, just for kicks, i added the listen=208.X.X.X:5060 listen=208.X.X.X:5060 listen=10.3.200.202:5060 Into my config to explicitly listen on my three IP addresses... and magically everything started working again.

Should I file this as a bug, or is there something I'm missing here and this was really a 'feature' and not a 'bug'? :) Either way, my problem is resolved now. Thanks everyone (especially Daniel, helpful as usual!)
