Hi All,
My company is using Vonage online PBX with Cisco SPA 303 IP phones, purchased direct from CDW and provisioned accordingly via Vonage provisioning instructions and tools. The issue I'm having is that from time to time, user phones show all orange lights and they have no dial tone. According to the documentation, orange lights indicate that the device is unregistered. By unplugging the power to the phone (resetting) it comes back online. Here are some notes:
I will do some more troubleshooting but wanted to start a discussion to see if anyone can shed some light on similar experiences, if any. This is what I will do:
Thanks all in advance for any feedback.

Everyone,
The issue was on the firewall device. The firewall device, a SonicWall TZ210, had a checkbox for Consistent NAT which was left unchecked. I found this bit of information when I searched Vonage's site. Here is the link for reference.

True. Orange light and missing dialtone mean that registration to SIP proxy has been lost.
So you need troubleshoot either network issue or Vonage issue.
Capture SIP packets related to affected phone. It will disclose you some important information. Also consider turning syslog&debug on. Captured syslog&debug messages are valuable source for the purpose of analysis.
The most important question is ...
... are REGISTER requests issued by phone responded by Vonage ?

Dan,
Thanks for the quick reply. I believe the SIP packets will tell me what I need to know to troubleshoot further, thanks for that suggestion.
Syslog and Debug, are those on the physical phones themselves? I'll check tomorrow when I'm in the office to see if that's what you mean.
I would assume sure yes that the register request are responded by Vonage how else would they function both before and after plugging and re plugging? Something is getting dropped and not establishing. Like you said network issue or Vonage issue is what I need to find out.
I will do some more digging and post up. Thanks Dan!

See picture. Note you need to arrange external syslog server (it's IP needs to be configured in). There are some syslogd servers even for Windows avaiable.
