Number portability allows a number to move geographically within a network, between different operator networks and, as IP telephony is introduced, between network technologies. Number portability thus becomes an important enabler for IP telephony, by allowing the smooth transfer of subscribers to the NGN/IMS network.

eServGlobal uses its’ experience in real-time call, SMS and SIP session control to integrate with existing telecom networks and OSS/BSS systems, to deliver number portability solutions for fixed, mobile and NGN/IMS networks.

NumberMax Number Portability is a number portability application to route calls, messages and sessions to the correct recipient operator and is designed for:

• Mobile Operators (GSM, CDMA)
• Fixed Operators (PSTN, NGN)
• International Carriers (TDM, VoIP, SS7 signalling, SMS)
