Operators are facing a new challenge posed by the enterprise mobile market. Although an increasing number of professionals prefer to use a mobile device instead of a traditional desk phone, mobile phones don't always integrate well with existing unified communications solutions.
To fullfil this need and stay ahead of the competition, fixed operators need to add mobility to their Centrex/PBX/UC offerings. Mobile operators also need to expand their offer, adding PBX features on top of their GSM network.
Our mobile platform 'ISTRA' (developed by our company Centile) enables fixed and mobile operators to deliver enterprise-grade value-added services to mobile users over today's networks.
Enreach has partnered with industry-leading softphone companies to enable mobile users to make and receive free or inexpensive phone calls over IP using Wi-Fi or data connections. The Centile ISTRA platform fully supports Mobile SIP phone softclient applications such as Media 5-fone, Bria from Counterpath and Acrobits.
If a user has both a fixed and GSM phone, all incoming calls are routed both to the PSTN number and the mobile GSM phone registered as a mobile extension. Both devices will ring simultaneously and the call will be connected to the phone where the user answers first. Even if the mobile phone is out of coverage or switched off, and a forwarding rule to voicemail has been set up, the call will be redirected to the ISTRA platform mailbox, and not to the mobile voicemail. This allows the end-user to have all of their voice messages in the same place. An email notification (with audio file attached) will also be sent.
With mobile twinning (also known as “multi terminal” or “mobile extension” feature) the user or admin can assign one extension to several devices. End-users are then reachable from several terminals (IP or non-IP devices), such as their desk phone, softphone and GSM phone. When calling the extension, both the main terminal and the twinned device will ring simultaneously, and the user can take the call from either device. Once a call is picked up from one phone, the other is still available to receive and place calls. If the call is not answered, it will be directed to the extension forwarding rules (voicemail, your assistant or any other destination e.g. another extension, home phone number).
Thanks to the unique voicemail box feature, the user can be available on several terminals (SNR) and keep a single mailbox as any regular IP Centrex user (avoid the redirection to mobile/fixed voicemail systems). If the voicemail service answers the call, this will then not be transferred to the “remote terminal”.
With the Voice Call Continuity feature, users can switch seamlessly from one terminal to another while in a conversation. For example, the user can make or answer a call from his IP phone and continue it on his mobile phone without any interruption to the call.
The ISTRA FMC router is a FMC VAS enabler for fixed-line operators. The router is hosted by a MNO, MVNE or MVNA and interconnects to different MVNOs, each having a Fixed VAS or Centrex platform. For users of these platforms, the FMC router anchors their mobile calls from the MNO’s network to the MVNO’s Centrex platform using SIP Forced Camel interconnect.
