System and method for provision of a second line service on mobile telephone

A method for routing communications from a subscriber device to a third device over a communications network, wherein the subscriber device has a primary number with a first voicemail service associated with the primary number and a second number, the method comprising the actions of:

• receiving a communication initiated by the subscriber device at a server platform, wherein the subscriber device initiates the communication, as originating from the second number, by initiating the communication using an application running on the subscriber device that initiates the communication such that it is routed to the server platform by a telecommunications network, the server platform being communicatively coupled to the telecommunications network but not being an integral component of the telecommunications network;
• determining that the communication was routed to the sever platform from the subscriber device based on the communication being directed to a relationship number without the inclusion of a prefix or suffix, the relationship number being a network addressable telephone number that is associated with the primary number of the subscriber device, a primary number associated with the third device and the second number of the subscriber device, wherein the relationship number together with the primary service number of the subscriber device is used to identify an actual calling number of the third party device and the second number of the subscriber device;
• based on the primary service number of the subscriber device and the relationship number, identifying the third party actual calling number and the second number of the subscriber device;
• redirecting the communication from the server platform towards the third party actual calling number and populate the calling line identifier associated with the communication with the second number;
• receiving a second communication at the server platform, the second communication being directed to the second number of the subscriber device;
• establishing a call to the subscriber device;
• and
• in response to the call not be answered, routing the call to a second voicemail service, wherein the second voicemail service is dedicated solely for the second number.

A method for enabling a mobile telephone to place and receive communications using a second telephone number existing within the same mobile telephone that includes a primary telephone number, wherein a first voicemail service is associated with the primary telephone number, the method comprising the actions of:

• assigning a second line service (SLS) telephone number to be associated with a particular mobile telephone having a primary telephone number;
• receiving a communication request at a server, the communication request being initiated by a first device using an application running on the first device that initiates the communication such that it is routed to the server through telecommunications network, and directed toward the SLS telephone number of the particular mobile telephone without the inclusion of a prefix or suffix;
• the server operating to identify the particular mobile telephone that is associated with the SLS telephone number by identifying an association between a primary number of the particular mobile telephone and the SLS telephone number;
• establishing a communications channel between the first device and the particular mobile telephone, the communications channel being identified as between the first device and the SLS telephone number of the particular mobile telephone;
• if the established communications channel does not result in a call being answered, the communications channel is directed to a second voicemail service that is associated only with the SLS telephone number;
• the server providing a relationship number to the particular mobile device, the relationship number being a valid telephone number that can be used by a user of the particular mobile device to initiate a call to the first device by dialing the relationship number;
• receiving a new subscriber initiated communication request from the particular mobile at the server, the subscriber initiated communication request being directed to the relationship number without the inclusion of a prefix or suffix;
• the server identifying that the relationship number indicates that the communication is to be directed to the first device and to be identified as originating from the SLS telephone number;
• establishing a communications channel between the particular mobile telephone and the first device;
• and
• populating the calling line identifier field with the value of the SLS telephone number.
