Fixed & mobile convergence solution

The enterprise mobile market presents unique challenges to the operators. The number of mobile professionals continues to grow, and even desk-bound users frequently reach more readily for the mobile than the traditional desktop phone to make a call. But mobile phones typically integrate poorly with the existing enterprise unified communications solutions.

To stay ahead of competition, fixed operators need to add mobility to their Centrex/PBX/UC offerings.  Whereas mobile operators need to capitalize on the GSM network by adding enterprises PBX features on mobile phones. 

As part of the Centile Any³ approach — Any service, over any network, on any device — Centile Istra Mobile platform enables fixed and mobile operators to deliver enterprise-focused value-added services to enterprise mobile users over today’s networks. 

Key features for fixed & mobile operator

 – Mobile voip Centile 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 3G connection.Centile Istra platform fully supports Mobile SIP phone softclient applications such as Media 5-fone, Bria from Counterpath and Acrobits.

 – Unique Number

when using a fixed and a GSM phone in the office, 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 that is the first to answer. Even if the mobile phone is out of coverage (or simply switched off) and a forwarding rule to voicemail has been set up, the call will be redirected to the Istra mailbox, and not to the mobile voicemail, allowing the end-user to have all of his voice messages at the same place. An email notification (with audio file attached) will also be sent.

 – Mobile Twinning  the mobile twinning, also known as “multi terminal” or “mobile extension” feature enables to assign one extension to several devices. It allows end-users to be reachable from several terminals (IP or non-IP devices), such as their desk phone, softphone and gsm phone. When someone calls the end-user extension, both the main terminal and the twinned device will ring simultaneously, enabling the end-user to 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 end-user does not answer the call, it will be directed to the extension forwarding rules (forward to voicemail, to your assistant, to any other destination e.g. another extension, home phone number…).

 – Unique 


The unique voicemail box feature allows the end user to be available on several terminals (SNR) and to keep a single mailbox as any regular IP Centrex user (avoid the redirection to mobile/fixed voicemail systems). When this feature is activated, the call will not be transferred to the “remote terminal” if the voicemail service answers it.

 – Voice call continuity

 Centile Voice Call Continuity feature enables users to switch, seamlessly, from one terminal to another while in a conversation. The user can for example, start a conversation on his IP phone and continue the conversation on his mobile phone, without the other party to notice.
