Why does my IP phone (i2004) display invalid TN?

If your IP phone is displaying the following message on screen it was probably programmed using DHCP and not the MAT terminal:

Invalid TN:
Reason: Unequipped

The virtual TN needs to be programmed on the Meridian 1.
The DHCP server sets up the configuration to the ITG card but does not send any information to the Meridian to programme the TN.

If MAT is showing error code SCH0128 which states that the TN does not exist, create the extension TN as NEW and transmit it to the Meridian.

For further information view,  How do I provide an i2004 telephone using automatic install?
