1. A method, comprising:
- sending, via a SIP device associated with an overriding user, an override signal to a SIP device associated with a first user wherein the first user is having a first dialog with a second user and the override signal includes at least one of a prefix of an address associated with the first user and an appendix of an address associated with the first user;
establishing a second dialog between the SIP device associated with the overriding user and the SIP device associated with the first user, wherein the SIP device associated with the first user sends a refer signal with contact information of the overriding user to the SIP device associated with the second user;
receiving, via the SIP device associated with the overriding user, an invite signal from a SIP device associated with the second user;
establishing a third dialog between the SIP device associated with the overriding user and the SIP device associated with the second user, in response to the invite signal, wherein the first dialog is terminated after the third dialog is established, wherein the second dialog and the third dialog are controlled by the overriding user, and wherein control by the overriding user comprises at least one of;
participating in at least one of the second dialog and the third dialog, dropping out of at least one of the second dialog and the third dialog, forcing out at least one of the first user from the second dialog and the second user from the third dialog, and terminating at least of the second dialog and the third dialog.

7. A system, comprising:
-
a device comprising a user agent configured to; send an override signal to a first user wherein the first user is having a first dialog with a second user and the override signal includes at least one of a prefix of an address associated with the first user and an appendix of an address associated with the first user; establish a second dialog with the first user; receive an invite signal from the second user; and establish a third dialog with the second user, in response to the invite signal sent by the second user based on a refer signal with contact information of the user agent from the first user, wherein the first dialog is terminated after the third dialog is established, wherein a refer signal is sent from the first user to the second user with a contact address of the user agent the third dialog with the second user, and wherein the second dialog and the third dialog are controlled by the user agent such that controlling the second dialog and the third dialog comprises at least one of;
participating in at least one of the second dialog and the third dialog, dropping out of at least one of the second dialog and the third dialog, forcing out at least one of the first user from the second dialog and the second user from the third dialog, and terminating at least of the second dialog and the third dialog. - View Dependent Claims (8, 9, 10, 11)

12. A method, comprising:
-
receiving, via a SIP device associated with a first user, an override signal from an overriding user while the first user is engaged in a first dialog with a second user and the override signal includes at least one of a prefix of an address associated with the first user and an appendix of an address associated with the first user; establishing a second dialog between the SIP device associated with the first user and a SIP device associated with the overriding user; and sending, via the SIP device associated with the first user, a message to the second user wherein the message comprises a contact address of the overriding user and an identifier identifying the first dialog; wherein a third dialog is established between the SIP device associated with the second user and the SIP device associated with the overriding user based on the message, wherein the first dialog is terminated after the third dialog is established, wherein the second dialog and the third dialog are controlled by the overriding user, wherein control of the second dialog and the third dialog comprises at least one of;
participating in at least one of the second dialog and the third dialog, dropping out of at least one of the second dialog and the third dialog, forcing out at least one of the first user from the second dialog and the second user from the third dialog, and terminating at least of the second dialog and the third dialog. - View Dependent Claims (13)

14. A method, comprising:
-
sending, via a SIP device associated with an overriding user, an override signal to a SIP device associated with a first user wherein the first user is having a first dialog with a second user and the override signal includes at least one of a prefix of an address associated with the first user and an appendix of an address associated with the first user; establishing a second dialog between the SIP device associated with the overriding user and the SIP device associated with the first user, wherein the SIP device associated with the first user sends a refer signal with contact information of the overriding user to the SIP device associated with the second user; receiving, via the SIP device associated with the overriding user, an invite signal from the SIP device associated with the second user, wherein the invite signal includes a header field for identification of the second user; establishing a third dialog between the SIP device associated with the overriding user and the SIP device associated with the second user, in response to the invite signal; transmitting, via the SIP device associated with the overriding user, a response signal the second user; and controlling the second dialog and the third dialog, wherein controlling the second dialog and the third dialog comprises at least one of participating in the first dialog and the second dialog, and dropping and ending at least one of the first dialog and the second dialog.
