I get the message: 3Com Model 3102- Wait for NCP M We have never seen this before and it is after a power outage. Our server is running. What is NCP?

As long as someone hasn't been poking around in the phone system, this is a phone company issue. I have seen this many times and it has always been a carrier issue. Typically with PRI's or integrated access analog lines.

The problem would be more than just internet in order for the phones not to work. they just need to be plugged in to a switch on the network to be able to communicate with the phone system and the other phones. Probably a switch or the DSL router if it has a built in switch.

I'm pretty sure that's set at the server level so that all the phones are synced, not at the phone itself.

Assuming you are talking about remote phones, you need to program the NCP (call processor) IP into the phones manually or add option 187 to your DHCP scope. The phones are able to DHCP the just also need to know what the IP address of the phone system to connect to is. If the phones are on your local network then this is all unnecessary. They work at layer 2 locally and don't need to use an IP address or DHCP.

This means that the phone and the NCP (Network Call Processor) in the phone system aren't communicating with each other. Multiple problems can cause this. Things to check:
1. Network cable - Is it plugged in, and to the right port?
2. Phone died
3. Is there an available license? (3100 series phones)
4. Is there a network switch problem causing a loss of communication through whatever switch that the phone is plugged into.

If the phones are only 6-8 months old you should be calling 3Com. those phones have a 1 year warranty and once you register them they will help you troubleshoot and replace them if needed. Can you provide more detail? Do you have any network issues while this is happening? Does speakerphone work but the handset doesn't?

Hi,
In most cases you just have to reset your modem and/or router, to do this just unplug the modem for the mains for 2 minutes, plug it back in and wait another 2 minutes for it to settle down, then you can try to reconnect to the server.



Regards.

I have only been able to get our phones to work when there is a VPN connection between the two locations.
