I was wondering if anyone is familiar with a product called Wintalk? I have had it installed for many years and recently lost the configuration and had to rebuild. I can't seem to figure out one small feature. There is an option for sending a code sequence to the phones to activate the message waiting light. Does anyone know what the code is that a Comdial TO616 switch would need to receive to activate the message waiting light? It would be some sort of key sequence.

Thanks
Joe
