A collaboration conferencing routing server may provide configurability in routing a collaboration conference to a conference bridge based on any number of criteria and information about the requester and the communications network on which the conference occurs. ## Claims ### Claim 1 A system for designating a master conferencing routing server from a plurality of collaboration routing servers in a telecommunications system, the system comprising: at least one processor; memory, operatively connected to the at least one processor and storing instructions that, when executed by the at least one processor, cause the system to perform a method, the method comprising: receiving a first total number of conference bridges to which a first collaboration conferencing routing server of the plurality of collaboration conferencing routing servers is locally connected; receiving a second total number of conference bridges to which a second collaboration conferencing routing server of the plurality of collaboration conferencing routing servers is locally connected; designating the master conferencing routing server from the plurality of collaboration routing servers based on the highest of the first total and the second total; and receiving a collaboration conference access request from a requester's communication; and selecting a hosting conference bridge from a plurality of conference bridges connected to the designated master conferencing routing server, wherein the hosting conference bridge is configured to host a collaboration conference. ### Claim 2 (depends on 1) The system as recited in claim 1, wherein the method further comprises: transmitting one or more routing messages to the telecommunications network, wherein the one or more routing messages include an indication of the selected conference bridge. ### Claim 3 (depends on 1) The system as recited in claim 1, wherein the method further comprises: associating an identification number with the collaboration conference access request, the identification number associated with a customer of a telecommunications network. ### Claim 4 (depends on 1) The system as recited in claim 1, wherein the method further comprises: requesting operational information of the plurality of conference bridges, the operational information comprising at least an available capacity for the plurality of conference bridges. ### Claim 5 (depends on 1) The system as recited in claim 1, wherein the operational information of the plurality of conference bridges further comprises at least one technical feature, and wherein the method further comprises: analyzing the at least one technical feature of the plurality of conference bridges. ### Claim 6 (depends on 1, 2) The system as recited in claim 2, wherein the selecting comprises: accessing a priority list of the plurality of conference bridges, the priority list configured to list the plurality of conference bridges in an order of preference based on the identification number. The system as recited in claim 1 wherein at least one conference bridge of the plurality of conference bridges is a session initiation protocol (SIP) based telecommunication device. ### Claim 8 (depends on 7) The system as recited in claim 7, wherein the method further comprises receiving an acknowledgement message from the selected hosting conference bridge that comprises at least an IP address of the selected conference bridge. ### Claim 9 A nontransitory computer readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform a method for designating a master conferencing routing server from a plurality of collaboration routing servers in a telecommunications system, the method comprising: receiving a first total number of conference bridges to which a first collaboration conferencing routing server of the plurality of collaboration conferencing routing servers is locally connected; receiving a second total number of conference bridges to which a second collaboration conferencing routing server of the plurality of collaboration conferencing routing servers is locally connected; designating the master conferencing routing server from the plurality of collaboration routing servers based on the highest of the first total and the second total; and receiving a collaboration conference access request from a requester's communication; and selecting a hosting conference bridge from a plurality of conference bridges connected to the designated master conferencing routing server, wherein the hosting conference bridge is configured to host a collaboration conference. ### Claim 10 (depends on 9) The nontransitory computer readable medium as recited in claim 9, wherein the method further comprises: transmitting one or more routing messages to the telecommunications network, wherein the one or more routing messages include an indication of the selected conference bridge. ### Claim 11 (depends on 9) The nontransitory computer readable medium as recited in claim 9, wherein the method further comprises: associating an identification number with the collaboration conference access request, the identification number associated with a customer of a telecommunications network. ### Claim 12 (depends on 9) The nontransitory computer readable medium as recited in claim 9, wherein the method further comprises: requesting operational information of the plurality of conference bridges, the operational information comprising at least an available capacity for the plurality of conference bridges. ### Claim 13 (depends on 9) The nontransitory computer readable medium as recited in claim 9, wherein the operational information of the plurality of conference bridges further comprises at least one technical feature, and wherein the method further comprises: analyzing the at least one technical feature of the plurality of conference bridges. ### Claim 14 (depends on 10) The nontransitory computer readable medium as recited in claim 10, wherein the selecting comprises: accessing a priority list of the plurality of conference bridges, the priority list configured to list the plurality of conference bridges in an order of preference based on the identification number. ### Claim 15 (depends on 9) The nontransitory computer readable medium as recited in claim 9 wherein at least one conference bridge of the plurality of conference bridges is a session initiation protocol (SIP) based telecommunication device. ### Claim 16 (depends on 15) The nontransitory computer readable medium as recited in claim 15, wherein the method further comprises receiving an acknowledgement message from the selected hosting conference bridge that comprises at least an IP address of the selected conference bridge.
