I have a user who has a Remote Office 9115 setup to a Meridian Option81, the 9115 connection is pstn. Everything works ok when he is connected to the Meridian. The problem is when he tries to se the unit in local mode, i/c calls are ok, on o/g he can receive dial tone from the local line but when he keys a number the main exchange is not recognizing the digits correctly & the call fails. I have tried another 9115 & another phone with the same results. I get the same problem if I use another line at the same location, but if I connect an analogue phone to these lines I can dial out ok. If I try the 9115 at a different location it works perfectly.
