I have an Amtelco PC-MX for telephone answering and voice-mail connected to a Mitel analog SX-100 which supports executive suite clients.

The Amtelco is an DOS based PC system which can send dial strings and interface with the Mitel.

A client on a Mitel extension that wants to get a message waiting indicator on his phone when the Amtelco operator sends a caller to the Amtelco voice-mail.

(While the Mitel console can send an MWI indicator, that console is not available to the Amtelco operator.)

The Amtelco can send an MWI signal to a telephone which has a message waiting indicator that "is the type that can be activated by a dial string."

Is there any way to send DOS based dial strings? (for example, 1R*7181,.*8181,W)through the Mitel system?

If so, what kind of hand set would be required?


Thanks in advance
