Analog set trouble

[casey14]

I have a system phone that is extension 4488 the analog phone assocoiated with this extension is 4481.
How do I change the extension 4481 to match extension 4488?

go to ld 20

Req PRT
type DN
dn 4481

This prints the TN

req CHG
type 500 for analog or model for digital ie 3904
tn enter TN as above
then scroll to DN
where it says DN then enter 4488
enter through the rest of the prompts
