What is the setting to make the voicemail dial the extension number after the MWI turn on or off code. I tried x but that did not work.

The lights turn on and off automatically when all the voice mail extensions are programmed into a voice mail group...usually group 1 access code 440.

I'm guessing that the OP is looking for the codes for an analog Talkpath to do this. The code to turn the MWI on is 420 plus the extension number. To turn it off, the code is 421 plus the extension number. Craig, are you asking us what the entry should be in the Talkpath's registry for this function?

In the COS settings, under the notification tab, there is a MWI set and clear sequence. What I was looking for was the characters to tell the talkpath to dial the extension after the set/clear code, which turns out to be @Ext.

I found what I was looking for. Thanks for your input though.
