Delivering calls, messages and sessions to 2G, 2.5G, 3G and VoIP devices

Your customers are used to the experience of Instant Messengers on PCs, where they manage their presence and availability in order to filter incoming calls, messages and video or conference sessions. PSTN telephones and 2G mobile phones did not provide these features in a convenient way. Switching off, call forwarding and silent mode were used instead. The advent of always-on IP connectivity on 2.5G-3G mobile devices, PDAs and gaming consoles opens up new possibilities to provide Value Added Services for incoming calls, sessions and messages, based on presence and availability information.

At eServGlobal, we use our experience in real-time call, SMS and SIP session control to integrate with your existing systems, and deliver these rich, personalised services. The Presence & Availability solution puts you and your subscribers on a smooth service migration path from PSTN to NGN, and from 2G-2.5G-3G mobile to the IP Multimedia Subsystem.
