I have a BT8600 phone with a problem when telephoning any call centre using menus which need to be selected using the handset. When using the handset number buttons to select a menu number, there is often no responce from the call centre. The tone does not seem to register at the call centre end. This often causes the call to fail. The handset tones are turned on and there is never a problem dialling a number. Similarly, I have a different phone which, when connected, does not have the same problem when using call centre menus. Any ideas how I can overcome this problem?
Thanks for that. I have two BT8600 handsets, both which exhibit the same problem. I also have a panasonic DECT phone, currently disconnected from the landline; but when plugged in does not have any problem selecting call centre menu's. It is only the 8600's I have a problem with.
