One embodiment includes a method for data communication with an end user, the method comprising connecting to an agent device; receiving a data session request from the agent device, wherein the data session request comprises a target telephone number; establishing a data session with an end-user device associated with the target telephone number; and transmitting data messages between the end-user device and the agent device using the data session. ## Claims ### Claim 1 A method for data communication with an end user, the method comprising: connecting a session server to an agent device; receiving, at the session server, a data session request from the agent device, wherein the data session request comprises a target telephone number; receiving, at the session server, a notification from an end-user device wherein the notification includes an end-user phone number and wherein the notification indicates the end-user device is available; establishing a data session between the agent device and the end-user device, wherein establishing the data session is based on the target telephone number and the end-user phone number; and transmitting data messages between the end-user device and the agent device using the data session. ### Claim 2 (depends on 1) The method of claim 1, wherein establishing the data session with the agent device comprises establishing the data session through an Internet server; and wherein transmitting data messages to the end-user device comprises transmitting data messages through a URL page. ### Claim 3 (depends on 2) The method of claim 2, wherein establishing the data session with the end-user device comprises locating the end-user device associated with the target telephone number. ### Claim 4 (depends on 3) The method of claim 3, wherein locating the end-user device comprises matching the target telephone number from the data session request with the end-user device associated with the end-user phone number that matches the target telephone number. ### Claim 5 (depends on 1) The method of claim 1, wherein transmitting data messages between the end-user device and the agent device comprises using a web page. ### Claim 6 (depends on 5) The method of claim 5, wherein transmitting data messages between the end-user device and the agent device comprises the end-user device and the agent device co-browsing the web page. ### Claim 7 (depends on 1) The method of claim 1, further comprising: establishing an end-user connection with the end-user device; and adding the end-user connection to a data structure. ### Claim 8 (depends on 7) The method of claim 7, wherein establishing the data session with the end user device comprises searching the data structure to locate the end-user connection with the end-user telephone number matching the target telephone number. ### Claim 9 (depends on 1) The method of claim 1, further comprising: creating a session identification for the session, wherein the session identification identifies the session. ### Claim 10 (depends on 9) The method of claim 9, wherein the session identification includes information to allow the end-user device and/or the at least one agent device to reconnect to the session if the end-user device and/or the agent device loses data connectivity. ### Claim 11 (depends on 1) The method of claim 1, wherein the agent device is an IVR. ### Claim 12 (depends on 11) The method of claim 11, further comprising: compiling session data during the data session between the end-user device and the IVR. ### Claim 13 (depends on 12) The method of claim 12, further comprising: transferring the session data to an agent workstation. ### Claim 14 A non-transitory computer readable medium encoded with instructions for performing data communication with an end user, the method comprising: connecting a session server to an agent device; receiving, at the session server, a data session request from the agent device, wherein the data session request comprises a target telephone number associated with an end-user device; receiving, at the session server, a notification from an end-user device wherein the notification includes an end-user phone number and wherein the notification indicates the end-user device is available; establishing a data session between the agent device and the end-user device associated with the target telephone number, wherein establishing the data session is based on the target telephone number and the end-user phone number; and transmitting data messages between the end-user device and the agent device using the data session. ### Claim 15 (depends on 14) The computer readable medium of claim 14, wherein: connecting to an agent device comprises connecting to an agent device using an Internet server; and transmitting data messages to the end-user device comprises transmitting data messages through a URL page. ### Claim 16 (depends on 15) The computer readable medium of claim 15, wherein establishing the data session with the end-user device comprises locating the end-user device associated with the target telephone number. ### Claim 17 (depends on 16) The computer readable medium of claim 16, further comprising: wherein locating the end-user device comprises matching the target telephone number from the data session request with the end-user device associated with the end-user phone number that matches the target telephone number. ### Claim 18 (depends on 14) The computer readable medium of claim 14, wherein transmitting data messages between the end-user device and the agent device comprises the end-user device and the agent device co-browsing a web page. ### Claim 19 A method for data communication with an end user, the method comprising: connecting a data session server to an agent device; receiving, at the data session server, a data session request from the agent device, wherein the data session request comprises a target telephone number associated with an end-user device; receiving, at the data session server, a notification from the end-user device wherein the notification includes an end-user phone number and wherein the notification indicates the end-user device is available; establishing a data session between the agent device and the data session server, wherein the data session is established through an Internet server gateway; connecting the data session server to the end-user device, wherein the end-user device is associated with the target telephone number; establishing the data session between the end-user device and the data session server, wherein establishing the data session is based on the target telephone number; and transmitting data messages between the end-user device and the agent device using the data session. ### Claim 20 (depends on 19) The method of claim 19, wherein transmitting data messages to the end-user device comprises transmitting data messages through a URL page.
