Hi

We have a very serious problem with our 7400 system. Users around our facility use the ** or a page button to set off a page to all handsets that are reistered in page group Zone 0 and an external tanoy system.

Recently this system has been failing. Now it happen almost every page (but usually from certain handsets) The symptoms are as follows:

Page initiated
Beeps start to signify page
Beeps continue longer than usual
User cannot perform page
Line goes dead

I have tried swapping the handsets but this has not worked.

I am completely lost for iedeas on this.

Please help

Richard
