ICP3300 and 5212 IP Phone

[Yanayaya]

Hello all,

I have a 5212 phone that I have plugged into our LAN. I have added a new user to the control panel. However the ICP shows the phone as out of service and the phone display simple shows "DHCP Discovery".

How do I bring the phone back into service?

Is this the only/first phone on the ICP or is this adding a phone to an existing setup? Troubleshooting will vary based on response.

Adding a phone to an existing setup.

Here's the steps I would take:
1. Move an existing phone to the same location (same lan connection) works? This will tell you if the network connection from that drop is good or not.
2. If the drop is good, check the settings on the phone and default them.

I like the statement "Sipmly shows DHCP Discovery"
I fact there are multiple layers of infrastructure involved into the process.

The reason for this message is that the phone cannot obtain an IP address. If someone else does manage your network, I'd recommend to invite them. If you do it yourself, then you should be able to do next simple steps.

1. Physical connectivity. Connect a computer to the cable and make sure you see ethernet link lights on both switch and network adaptor.
2. If you don't have voice vlan, and your computer set to use DHCP, then it should obtain an IP address.
3. If you do use voice vlan, then things getting more complicated and you need to check CAM tables (MAC address tables) on your switches.
4. Make sure that DHCP process is running. Connect a computer to access port of your voice network and confirm that you got an IP address.
5. If nothing helps try to set your phone to static config. Use button "2" features.
6. If your computer can obtain an IP address and the phone cannot, check connector pins in the phone. Try to connect a computer in aux jack on the phone. Are you able to get connected from there while the phone is discovering DHCP.

And so far so on...

As mentioned above there are numerous things that could cause this trouble.

I am making the following assumptions:
- A PC gets DHCP in the same jack.
- Your normal setup does not have dedicated jacks for the phone and has the PC plugged into the back of the phone.
- The cable from the phone to the jack is known to be good (works with another phone)

With the above being true I would proceed as follows.
- Reset a known working phone in a known working location and observe the boot sequence.
1 Does the known working phone do a DHCP discovery?
2 Does the known working phone do more than 1 DHCP dicovery ("releasing" displayed in between)
3 Does the known working phone display a VLAN other than 0 (zero)

Now I would plug the new phone into the same location as the known working phone.
- How does the boot sequence differ?

Report you findings.
