Fixed Mobile Convergence (FMC)


This service groups together multiple fixed and mobile devices. Each device in the group acts as an alias to the each other device in the group. The devices could be an extension of a PBX or a subscriber’s individual landline or mobile phone. In both cases it works as follows:


Incoming Calls


Incoming calls to a phone are checked for aliases. In case aliases are present, the calls are sent to the called number and the aliases just like Follow Me/Find Me scenario, according to the sequential or parallel preference set at the FMC service level in subscriber’s profile. The default is to try the main extension as well as aliases in parallel.



Outgoing Calls


The simple case of outgoing calls deals with setting the Caller ID for each call made by a group member to any external destination. One of the group members can be set as the caller ID for all calls originating from a group member phone.


An advanced case of outgoing calls enables remote outgoing calling. In this case, one of the phone numbers in the FMC group is set as an access number for outgoing calls in the group. The subscriber dials the designated access number for the group from any other group member phone. The system recognizes the group member from the CallerID and automatically gives the user a new dial tone to dial out a destination number.



Transferring calls between fixed and mobile



Subscriber initiated


The subscriber can switch calls using hot-keys between fixed VOIP number/extension and its mobile alias, just like simple call transfer service available in a PBX.


System initiated (seamless)


An advanced form of this service (if enabled on the subscriber’s profile) allows the subscriber to automatically switch an ongoing mobile to the fixed line when the fixed device registers.

For example, an incoming call is sent In parallel to landline extension and its mobile alias but the landline extension is offline at the time. The call connects to the mobile and is still connected when the landline phone registers with the system. The system automatically transfers the call to landline without the calling party even noticing it.


Mobile dialers and other registered devices


This is an optional feature of FMC and can be used if the CSP chooses to provide mobile dialers for smart-phones or any other form of SIP based devices to their subscribers, in addition to the main registering device. In this case, each device, including the main one, registers with the same SIP URI and provides its own priority at the time of registration in standardized SIP parameters (q-parameter). This gives information to the system in the order of priority in which the devices have to be sent incoming calls in case multiple registrations are found.

Subscriber initiated transfer works the same way as for the mobile phone case between multiple registered devices. This means the subscriber can transfer calls between multiple devices using hot-keys followed by a device priority. For example, a call is connected to a mobile dialer with priority 2. In the middle of the call, the subscriber wants to transfer to the main device with priority 1. He presses a hot-key followed by 1 to initiate the transfer.
