We are in the process of setting-up a new HDX8000 and found that audio/POTS call handling seems to be limited (when compared to our old Tandberg 95 MXP).
- Can the HDX8000 receive and bridge incoming audio calls on ALL available ISDN channels?
-- We were only able to connect two audio lines simultaneously. Why can't we use the other four channels?
- We are not able to establish voice communication with incoming telephone subscribers.
-- We can respond to and answer the incoming call but the far-end can't hear us
-- We can here far-end but not audio is transmitted from near-end
-- The call is disconnected by the HDX8000 after about 3 minutes or so
-- This symptom only occurs when the incoming telephone call is the first active connection/call
-- This symptom always occurs when the incoming call is from analog or digital phone
- The HDX8000 (just as the Tandberg 95 MXP) has a LAN connection and three ISDN lines (6 channels).
You will need the HDX multipoint license. I did some testing with my HDX which has a PRI line and was able to make mutiple ISDN audio calls both in and out.
Ken, I also can place calls to multiple phones (via ISDN). Our problem comes up when we receive an audio call; and it is the first active call/session.
So, if a call/session is already active, I don't experience any issues with incoming phone calls. However, if I receive a phone call to an idle system, my audio doesn't transmit and the call is disconnected after about 3 minutes. I'm then forced to identify the caller and call them back.?.?.
