Hello, We have a TDM400P with 2 ports running on a * server with a 4 port BRI card but we are having some difficulties. When we make a voice call, the sound is perfect, no echo, very usable, however every 6 to 12 seconds you here a slight stutter in the sound which is faint but defiantly there. This also occurs while just sitting there at a dial tone before dialing out. Anyone got any ideas. I tried swapping cards around, same problem. I have tried plugging a fax and a modem onto the two ports, am having no luck making data calls or receiving faxes, I think the line stutter is the problem (I did add a d option to the dial command as recommended by previous posts to list). Any thoughts?
