Hi, On telkom landline account I subscribe to the option "telkom anytime" which does not bill me for local calls. However there is a section on my itemised bill for "mobile operators" as well as "other operators" which I am billed for. The mobile operators I can recognise however the "other operators" whose numbers can start with 011 or 012 and that seem like local telkom lines are difficult to distinguish from local telkom landlines. Thus when making calls for example with a number starting with 011....., I would like to know prior to making the call if this is a telkom landline or one of the "other operators".Any ideas as to how to distinguish the difference?
