The operator want to call an external number, and then, without expecting to attend, transfers the call to a internal number (her boss); the operator hungs of; and the boss is waiting for the external hung up.
Go to external lines --> protocols --> analog trunks 1 NDDI and press modify:
Modify all Off-Hook simul timers to the time you want. In analog time I use 3000 ms.
Go to external lines --> protocols --> analog trunks 2 PCM and press modify:
Modify all Off-Hook simul timers to the time you want. In analog time I use 3000 ms when I don't have metering. When I have metering I use 90000 ms. Why this? Because in PCM trunks you have Off-Hook signaling. You put these times as 3000 ms, if B side answers after this 3000 ms all tickets are printed with call duration time as 00:00 . You put these times as 90000 ms, when B side answers the tickets are printed with call duration time due to Off-Hook signaling from E1 PCM R2.
