National numbering plan expansion cannot address just one segment, such as new registering customers, it has to address all user segments. Yes, the updates of contact lists etc. will have to take place, however it’s a minor interruption compared to interrupted telecommunications services due to the numbers shortage and networks overload. This change addresses the increasing demand for both fixed and mobile phone numbers in Qatar. In regards to the ETR issue, you are right, it’s an operator issue and Qtel should be able to address it.
