Unity 4.2 using PIMG on NEC 2400 PBX 32 ports
Under busy traffic conditions calls are intermittantly showing no integration and defaulting to "direct call" with no display.
Under light load all calls ok with integration and proper greetings
I have changed the following:
; Maximum Call Party Delay (ms): Number between 0 - 10000
telCallInfoTout = 4000
to force PIMG to wait up to 4 secs for call display to show up.
Any other ideas? Could it be a failure on the NEC side?
