I connect 2 ISDN Lines from the PSTN Terminal Interface ( ab1 , ab2 ) .
The problem is when i have incomming call in one ISDN , both of the PSTN Terminal Interfaces ringing and the PBX rings two or more phones .
The first available person pickup the first line but the second person pickup nothing just tone .
Is there a solution for that event ?
Any ideas ?
Thanks in Advance
