Cetis Hospitality phones and line selection for Avaya ip office 500v2

[CPM86]

I'm enjoying my home lab setup. I finally got used from e-pay 2 Cetis hotel phones. These are analog phones and have a few or tons of programmable feature buttons.
One of the used phones have a already-designed template. 4 of the programmable buttons are labels line 1-4. So I started thinking if I could find or create a short code
to give me a line selection. This would be with using the analog phone 2 card and version 8.0 release.

Thank You,

Josh

The only way I can think to do this, and I don't see an application for it in the real world, would be to put each line into its own outgoing line group, then create matching ARS tables, and finally 4 short codes (9N, 8N, 7N, 6N / Dial / N / Use Line group - choose the appropriate ARS table.
This would only allow you to select a line to dial out on, you wouldn't be able to choose a line on one phone that had been put on hold at another.
