Hi again guys, as it is a different issue, I open a new thread:

Actually this PBX is installed on a ship, and I just replaced the VSAT (satellite link) system that provides us both data and voice. All is working okay for data network, but as we changed the provider we also received new phone numbers, so the demux offers me 8 analog phone lines (identical two previous config) on those 8 lines 6 are direct and 2 are prepaid.

After removing the old equipment I plugged back the 8 lines to PBX and I'm able to place outgoing calls but first it randomly falls on the prepaid lines. Also I'm not able to make incoming calls from the outside (i.e: when I try to call one of our attributed phone numbers, it rings one time then hangup) like if the PBX did not know where to switch the incoming call...I'm a pure IT and network and I've got only a very reduced knowledge in telephony systems, but I can give any needed informations, can take all pictures needed.

Thanks again gents, for all the help you could provide.

PS: I'd just like to precise that we're actually in shipyard in Santander (Spain) and it's very hard to find an Ericsson PABX specialist here...that's why I'm requesting your help, I know it is not my job but I full ready to execute the instructions that you could give me.
 
Hi zorglub,

If you want to debug analog lines, the first step is always to disconnect PBX, connect analog telephone set, and see what is going on.
Check if incoming and outgoing calls are working when you connect VSAT to analog telephone set, and let us now.
