www.WirelessFederation.com/news: According to a media report, it is indicated that launch of MNP in a phased manner is not possible. Apart from this, there are problems in call routing and charging in the MNP scenario, no pan-India readiness for MNP; and difficult to meet the government set deadline for implementing MNP, report said. There is also a technical clash between location routing numbers (LRNs) and STD codes in at least 200 sites. However, Department of Telecom (DoT) has asked all service providers to stick to the timeline.
