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:
- When phone is all orange, computers plugged into the SW port still function.
- DHCP server lease has been reduced to 12 hours to combat limited IP address issues.
- Network bandwidth is not an issue as we are running 100Mb D/U and tested at a sustained 80Mb/s in peak hours.
- Once a phone is all orange, it does not recovery itself at any time.
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:
- Once I unplug and replug, I will see if the device is issued the same IP address or not.
- Tomorrow, 3/3/15, I am doing a network overhaul with configured switches and Class B addressing so my DHCP lease can set it back to normal, 7 days.
- I will re-provision affected phones to see if an old configuration is the problem.
Thanks all in advance for any feedback.
