I re-installed our ESI IVX S-series (Soho?) system and five 48-key handsets.

I desparately need Installer or at least Auto attendant function codes, instruction, help, etc.

The immediate needs are:
Change # rings before Auto-att. picks up.
Transfer incomming call to Auto attendant manually BEFORE answering call?
Can incoming call be transferred to other mailbox manually BEFORE answering call?

Can anyone walk me through, show me, or supply the correct function or instructions on above and/or general Auto-attendant or Installation programming?

Ant information would be gratly appreciated - Thank You,
Howard
