Hi,
We are having a problem with a phone system we manage. The device is a UC540, which has approximately 16 phones attached. Periodically there are received phone calls which generate a recurring beeping noise. There is nobody calling, it just appears to be a beeping noise, what is causing this I'm unsure. Can you please advise if this is a problem that you have come across before?
We have talked to the service providers and they have tested and confirmed there are no problems on the line.
Thanks
Adrian
