I have a KX-TD1232 system, when someone calls from the outside he hears the voice mail system and if he press 0 it goes to the front desk secretary. If she is using he phone at this moment the phone is still rings and she can switch line.

The problem is that if someone from inside of the company (internal extension) press 0 while she is on the phone he gets a busy dial.

Is there any way to program the Panasonic that when someone from inside will press 0 while she is on the phone it will ring her (like it rings when someone from external line calls) and she will be able to switch to this call ?


Thank you.
