Two questions about Message Control

Two questions about Message Control

Hi,
I have bought a modem as you proposed to try the Message Control function.
Microlink 56k Fun USB – Devolo
With Windows XP, the function of telephone call (wav files) works well at my laptop for a test. But I have still two questions:
1) In fact, in my company, the ZenOn runs as Server-Client mode. That means, our PC for ZenOn Run-Time works as a server, and another PC for ZenOn Editer works as a Client. The client must connect to the Run-Time server to refresh modifications for Run-Time.
My question is : In this condition, must I installer the driver of the Modem to all these two PCs? What should I do if the driver information is not identical? For example, one uses COM8, and another uses COM10? And must I plug this Modem when I use PC Editer, and replug to the PC Run-Time when I finish the modification?

2) I don't know why my Telephone (Speech) doesn't work.
[Message Control] -> [Propreties] -> [Transfer Media] -> [Settings for Speech Message] -> [Settings] -> [Speech output active]
Here I can test my speech output correctly.
But
[New function] -> [Message Control] -> [Telephone (Speech)] -> [Greeting].. etc.
When I input some text, the [play] button doesn't work. And finally, when I try at the Run-Time, my modem doesn't work at all (even the 'connect' led does not work).
So what is the problem of this function ?
Thanks at advance
