Hotline on an analog phone 2

[aben16]

Good day,
I need your help on setting up an analog line to automatically dial a DN.
I found a lot of interesting helpful links in this forum but it did not work for me. I am getting an error message.

Here is what I get:

REQ: chg
TYPE: 500
TN 20 0 0 0
ECHG yes
ITEM ftr hot SCH5537
FTR HOT SCH5537

is there something I am doing wrong?

SCH5537 is invalid autodial.
First thing you need to do is
FTR XADL

Shut up Harold, and load the Photon Torpedoes...

Yes It worked.
Thank you very much TAnselm for your response.
Thanks also to Johnthephoneguy for all the suggestions and for your quick responses.
