Canada

I have the Siemens C56 as well and I have the fon thru Rogers ATT wireless and live in eastern Canada I also work for ATT Wireless in the US. As well i am having the same problem as u described and u r right there is no mention in the manual on how to turn these tones off and using the systems @ work there is no mention of these tones either, but yet they r quite annoying. I believe that they r just letting u kno that the fon is trying to connect to the GSM system cuz the less signal i have the more beeps i get. As for how to turn the beeps off........Your guess is as good as mine. Sorry
