1. Set up and associate the physical phone.
   The easiest way to avoid searching through lines of configuration or hunting an automatically registered phone is to set up the phone association before plugging it in to a switchport on the network. In other words, give the router a "heads up" that the phone is about to be initialized.
THHQRV1-3845# configure terminal
THHQRV1-3845(config)# ephone 1                              #Configuration mode for ephone      
THHQRV1-3845(config-ephone)# mac-address 11aa.22bb.33cc   #The MAC address for the phone
THHQRV1-3845(config-ephone)# button 1:5                #Assign buttons to the phone by using the ephone-dn
THHQRV1-3845(config-ephone)# type 7962                #Set the phone type
THHQRV1-3845# show ephone ?                                  #Show a list of supported phone types.

THHQRV1-3845# configure terminal
THHQRV1-3845(config)# ephone-dn  1  dual-line        
THHQRV1-3845(config-ephone-dn)# number 7222
THHQRV1-3845(config-ephone-dn)# pickup-group 10

THHQRV1-3845(config-ephone-dn)# name Sumuscha Teesr
THHQRV1-3845(config-ephone-dn)# call-forward busy 7111
