Question about Actiontec (DHUSB00020C01)
I gather you are using an IP phone. I would have to say that the only way to trouble shoot is to use a protocol analyzer. If you connect it within the IP path you will be able to see both ends of the call and determine if the call was received or not and if the other end is responding to your call. Your IP PBX might be the problem I would run a diagnostic on it and if it fails, I would suggest calling the manufacture to see if there are any tests you can run.
