I have a new BT4600 phone that certain people can't hear me when phoning them. My voice is very faint to them. Other people I have no problem and they can hear me just fine.
Any ideas please?
Phone and broadband provider is BT.
Have you made sure that there is a microfilter in the lead to the phone, as any broadband signal getting into the phone, will impact on its performance?
I phoned the number and the phone line was checked (no problem) so they suggested trying a new filter.
Appreciate all of your suggestions.
