1. A method of transmitting data between two parties, 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 and/or a sequence number to the mobile device;

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

locating, in response to the received call, the stored portion of information associated with the request corresponding to the call;

receiving a request for a session initiation protocol (SIP) proxy from a client;

transmitting an internet protocol (IP) address associated with the SIP proxy along with the stored portion of information and/or the sequence number to the client; and

redirecting the call between the mobile device and the contact to a server via the SIP proxy.

2. The method of claim 1 , wherein receiving the SIP proxy request comprises receiving the SIP proxy 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 the 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 along with the sequence number.

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 sequence number to locate the stored portion of information.

6. The method of claim 1 , wherein the client corresponds to a fat client.

7. The method of claim 1 , comprising:

authorizing and/or authenticating the mobile device for the received call based upon authentication and/or authorization information, the authentication and/or authorization information including the stored portion of information and/or the sequence number; and

transmitting the authentication information to the SIP proxy.

8. 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 a real-time transfer protocol (RTP); and

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

9. The method of claim 1 , wherein the sequence number corresponds to a dual-tone multi-frequency (DTMF) sequence.

10. A first server configured to facilitate a transmission of data between two parties, comprising:

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

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

means for transmitting one or more of a data network identifier and/or a sequence number to the mobile device;

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

means for locating, in response to the received call, the stored portion of information associated with the request corresponding to the call;

means for receiving a request for a session initiation protocol (SIP) proxy from a client;

means for transmitting an internet protocol (IP) address associated with the SIP proxy along with the stored portion of information and/or the sequence number to the client; and

means for redirecting the call between the mobile device and the contact to a second server via the SIP proxy.

11. The first server of claim 10 , wherein the means for receiving the call comprises:

means for receiving the call along with the sequence number.

12. The first server of claim 11 , wherein the means for locating the stored portion of information comprises:

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

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

means for using the sequence number to locate the stored portion of information, if the mobile subscriber integrated services digital network number is not available.

13. A non-transitory computer readable medium including instructions, which, when executed by a first server, cause the first server to perform operations to facilitate a transmission of data between two parties, the instructions comprising:

instructions configured to receive, from a mobile device, a request associated with placing a call to a contact;

instructions configured to store at least a portion of information associated with the request;

instructions configured to transmit one or more of a data network identifier and/or a sequence number to the mobile device;

instructions configured to receive the call from the mobile device, wherein the call is initiated to the data network identifier;

instructions configured to locate, in response to the received call, the stored, portion of information associated with the request corresponding to the call;

instructions configured to receive a request for a session initiation o protocol (SIP) proxy from a client;

instructions configured to transmit an internet protocol (IP) address associated with the SIP proxy along with the stored portion of information and/or the sequence number to the client; and

instructions configured to redirect the call between the mobile device and the contact to a second server via the SIP proxy.

14. The non-transitory computer readable medium of claim 13 , wherein the instructions configured to receive the call comprises:

instructions configured to receive the call along with the sequence number.

15. The non-transitory computer readable medium of claim 14 , wherein the instructions configured to locate the stored portion of information comprises:

instructions configured to determine whether the call comprises a mobile subscriber integrated services digital network number;

instructions configured to use the mobile subscriber integrated services digital network number to locate the stored portion of information, if available; and

instructions configured to use the sequence number to locate the stored portion of information, if the mobile subscriber integrated services digital network number is not available.

16. A first server configured to facilitate a transmission of data between two parties, comprising at least one processor, the at least one processor being configured to:

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

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

transmit one or more of a data network identifier and/or a sequence number to the mobile device;

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

locate, in response to the received call, the stored portion of information associated with the request corresponding to the call;

receive a request for a session initiation protocol (SIP) proxy from a client;

transmit an internet protocol (IP) address associated with the SIP proxy along with the stored portion of information and/or the sequence number to the client; and

redirect the call between the mobile device and the contact to a second server via the SIP proxy.

17. The first server of claim 16 , wherein the at least one processor is further configured to:

receive the call along with the sequence number.

18. The first server of claim 17 , wherein the at least one processor is further configured to:

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

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

use the sequence number to locate the stored portion of information, if the mobile subscriber integrated services digital network number is not available.
