and a call server, wherein the registry device is configured to, receive contact information relating to a single identifier from an uploading device, the contact information identifying at least one protocol, store the contact information received from the uploading device, retrieve the stored contact information and transmit a message including the contact information, in response to a request from the call server for the contact information relating to the single identifier, and the call server is configured to, receive a request from a first communication device to establish a call to a second communication device associated with the single identifier, request, from the registry device, the contact information relating to the single identifier, receive, from the registry device, the contact information relating to the single identifier, and establish a call between the first communication device and the second communication device associated with the single identifier using the at least one protocol. ### Claim 2 (depends on 1) The system according to claim 1, wherein the call server, in response to failing to establish a call between the first communication device and the second communication device associated with the single identifier by using the at least one protocol, is configured to establish the call using a second protocol. ### Claim 3 (depends on 1) The system according to claim 1, wherein the contact information identifies at least one Internet Protocol (IP) protocol. ### Claim 4 (depends on 1) The system according to claim 1, wherein the call server, when requesting from the registry device contact information relating to the single identifier, is configured to include in the request at least one protocol supported by the call server. ### Claim 5 (depends on 4) The system according to claim 4, wherein the registry device, when transmitting the message including the contact information, is configured to only include the at least one protocol supported by the call server. ### Claim 6 (depends on 1) The system according to claim 1, wherein the registry device, when retrieving the stored contact information relating to the single identifier and at least one of no suitable protocol exists in the registry and no contact information exists in the registry, is configured to transmit a second message indicating that no suitable contact information is available. ### Claim 7 (depends on 1) The system according to claim 1, wherein the call server, upon receiving a message that no suitable contact information is available, or upon the call server having tried to establish a call on the at least one protocol, is further configured to establish a telephone call using the single identifier as a telephone number. ### Claim 8 (depends on 1) The system according to claim 1, wherein the single identifier is a telephone number. ### Claim 9 (depends on 1) The system according to claim 1, wherein the single identifier is an email address. ### Claim 10 (depends on 1) The system according to claim 1, wherein the single identifier is a social security number. ### Claim 11 (depends on 1) The system according to claim 1, wherein the single identifier is a national identification number. ### Claim 12 (depends on 1) The system according to claim 1, wherein the call server is incorporated in one of the first communication device and the second communication device. ### Claim 13 (depends on 1) The system according to claim 1, wherein the at least one protocol is at least one of Session Initiation Protocol (SIP), H.323, and Jingle. ### Claim 14 A method for establishing a call using a single identifier, the method comprising: receiving, by a registry device, contact information relating to the single identifier from an uploading device, the contact information identifying at least one protocol; storing, by the registry device, the contact information received from the uploading device; retrieving, by the registry device, the stored contact information and transmitting a message including the contact information, in response to a request from a call server for the contact information relating to the single identifier; receiving, by the call server, a request from a first communication device to establish a call to a second communication device associated with the single identifier; requesting, by the call server, from the registry device, the contact information relating to the single identifier; receiving, by the call server, from the registry device, the contact information relating to the single identifier; and establishing, by the call server, a call between the first communication device and the second communication device associated with the single identifier using the at least one protocol. ### Claim 15 (depends on 14) The method according to claim 14, further comprising establishing, by the call server, the call using a second protocol in response to failing to establish a call between the first communication device and the second communication device associated with the single identifier by using the at least one protocol. ### Claim 16 (depends on 14) The method according to claim 14, wherein the contact information identifies at least one Internet Protocol (IP) protocol. ### Claim 17 (depends on 14) The method according to claim 14, further comprising including, by the call server, in the request at least one protocol supported by the call server, when requesting from the registry device contact information relating to the single identifier. ### Claim 18 (depends on 17) The method according to claim 17, further comprising including, by the registry device, the at least one protocol supported by the call server when transmitting the message including the contact information. ### Claim 19 (depends on 14) The method according to claim 14, further comprising transmitting, by the registry device, a second message indicating that no suitable contact information is available when retrieving the stored contact information relating to the single identifier and at least one of no suitable protocol exists in the registry and no contact information exists in the registry. ### Claim 20 (depends on 14) The method according to claim 14, further comprising establishing, by the call server, a telephone call using the single identifier as a telephone number, upon receiving a message that no suitable contact information is available, or upon having tried, by the call server, to establish a call on the at least one protocol. ### Claim 21 (depends on 14) The method according to claim 14, wherein the single identifier is a telephone number. ### Claim 22 (depends on 14) The method according to claim 14, wherein the single identifier is an email address. ### Claim 23 (depends on 14) The method according to claim 14, wherein the single identifier is a social security number. ### Claim 24 (depends on 14) The method according to claim 14, wherein the single identifier is a national identification number. ### Claim 25 (depends on 14) The system according to claim 14, wherein the call server is incorporated in one of the first communication device and the second communication device. ### Claim 26 (depends on 14) The method according to claim 14, wherein the at least one protocol is at least one of Session Initiation Protocol (SIP), H.323 and Jingle.
