Abstract

The present disclosure relates to transmitting data between a plurality of computing devices such as mobile telephones and other electronic communications devices, where a request is associated with placing a call to a contact, and where information associated with the request is stored and a request for a SIP proxy is made, and an IP address associated with the SIP proxy is transmitted to allow redirecting the call to a server via the SIP proxy.

Claims

1. A method of transmitting data between two computing devices, the method comprising:

receiving, from a mobile device, a request associated with placing a call to a contact;

storing at least a portion of information associated with the request;

transmitting one or more of a data network identifier;

receiving the call from the mobile device, wherein the call is initiated to the data network identifier;

locating the stored portion of information associated with the request corresponding to the call;

receiving a request for a SIP proxy;

transmitting an IP address associated with the SIP proxy; and

redirecting the call to a server via the SIP proxy.

2. The method of claim 1, wherein receiving a request comprises receiving a request that comprises one or more of a session identification number and a contact identification number.

3. The method of claim 1, wherein storing at least a portion of information comprises storing one or more of a mobile network code, a mobile country code, a session identification number, a contact identification number a mobile subscriber integrated services digital network number and a name associated with the contact.

4. The method of claim 1, wherein receiving the call comprises:

receiving the call comprising a dial-tone multi-frequency sequence.

5. The method of claim 4, wherein locating the stored portion of information comprises:

determining whether the call comprises a mobile subscriber integrated services digital network number;

if so, using the mobile subscriber integrated services digital network number to locate the stored portion of information; and

if not, using the dual-tone multi-frequency sequence to locate the stored portion of information.

6. The method of claim 1, wherein receiving a request for a SIP proxy comprises:

receiving a request from a fat client.

7. The method of claim 1, wherein transmitting an IP address associated with the SIP proxy comprises:

transmitting an IP address associated with the SIP proxy to a fat client.

9. The method of claim 1, wherein redirecting the call to a server via the SIP proxy comprises:

providing, by the SIP proxy, an audio channel by summoning an RTP; and

initiating communication with a computing device associated with the contact over the RTP.

8. The method of clam 1, wherein redirecting the call to a server via the SIP proxy comprises:

transmitting authentication information to the SIP proxy.
