Public Addressing system waiting for "line reversal" from VG224

Hello

 

I am trying to setup a Public addressing system connected to VG224 via FXO ports.

We need the PA to start recording voice and transmit over external speakers which is not happening.

the PABX company is saying "the PA TZM8 is waiting for a “line reversal” via the VG224" and that is the reason why this is not working.

Any advice as to how to setup line reversal of the VG224?

 

Any advice will be much appreciated.

Many Thanks
