So it appears I have everything setup correctly. AA #1 is named Main Greeting. I have recorded a greeting. I have set the incoming route destination to Main Greeting. I can even hear a click like something answers, but dead air and then a disconnect..

Figured it out, I need a time schedule defined in order for it to play.

Now I just need to know how users check their messages remotely. I tried the default short code of *99, and setting a destination, but its not working.

Is this a IP Office 500 and which version?

I asume you are talking about an IPO 500 V2 R.7..........
Have you set a PW for the MBs?

I did have one password set on my test mailbox. I had the # key pointed to short code *99, with *99 defined as Voicemail Collect.

To keep my Embedded VM's more similar to Partner Messaging, I make a 2nd AA, send selector code 7 to *17. In the main AA, make * go to the 2nd AA, don't record any message in the 2nd one. Now you're dialing *7 from the main AA to log into voice mail.

Make a 3rd AA, Selector Code 1 transfers to *8401, which is record he OGM for the first AA, the greeting says "press 1 for thr day menu, press 2 for the night menu" (if you in fact have a day and a night AA). Back in that 2nd AA, 0 transfers to this 3rd AA. Now you can dial *0 from the main AA and change the greeting remotely.

I must have not programmed my own short code correctly.. But obviously if I just point it to *17 it works great! thats what I needed...
