2 speech calls on a WCBRI station

[luccollaer]

Hi,

We have a customer with a specific application that's needs to setup two ISDN speech calls to different numbers.

We connected this application to a TN556D port on a WCBRI station with the data module enabled.

We can setup 1 voice speech call but the second one fails.
When I try the same with an ISDN tester I can setup only a second call when this is a data call (data module)

Is there a way to setup this that I can setup 2 speech calls with a WCBRI station ?

Strange thing is that we can receive 2 speech calls on that port.


I know that I can do this with a trunk configuration but then I need an other ISDN card. Correct ?
