| one way that i can help you is 6to reset the system so that all phones will ring and the outgoing mesage will be erased.open the pabx then turn it on.you will see a switch at the right side, switch it then press the little button beside it.let it blink for 2 seconds then switch it back again.all parameters will be set to default and all the extensions will ring.it is the easiest way since you dont have a proprietary telephone.ok. |
