Hello, One of our customers has an issue with the unity 4.2(1): They have a welcome message, and after it, it is suppossed to transfer the call to the operator.
Everything works perfect, except that it doesn't give a notification tone back to the caller, it just says "wait until we try to transfer your call" and remains silent, althought the operator's phone is ringing. If, for example, the operator is busy with another call, the caller has the sensation that nothing is happening because he/she doesn't hear anything.
It happens with all IP phones, but if you change the operator extension by an analog phone connected to an FXS port, you receive the notification tone correctly.
Does anyone know how to correct this issue?
thanks in advance
