OK friend has BT line, had few issues with crackle and also internet dropping out. 2 engineers later phone working, next week DSL light goes on the modem, i come and have a look, all looks OK for settings, im thinking BT issue.
she logs call with BT they say go to AOL, AOL say go to BT, i come back around, the phone works if plugged in direct to the socket. If you plug the ADSL filter in (tried 3 or 4) you cannot make phone calls.... that's just the filter not even the router/modem, so surely BT ??
i dont want her to get charged!
