Abstract

Systems, methods, and machine-readable media are disclosed for providing customization to routing of messages in a system where routing is based on stored addresses, such as, for example, a Session Initiation Protocol (SIP) system, to pass through a firewall. In one embodiment, a method of providing customized routing of messages to pass through a firewall can comprise receiving a message from an initiating agent to a target communication identifier at a system for signaling between endpoints. The system can have one or more stored network addresses for each of a plurality of communication identifiers. One or more network addresses for the target endpoint can be determined from the stored network addresses associated to the communication identifier. One or more policies can be applied to the one or more network addresses for the target communication identifier to route the message through the firewall.

Claims31

Dependent claims

A method of providing customized routing of messages to pass through a firewall, the method comprising:

receiving a message from an initiating agent to a target communication identifier at a system for signaling between endpoints, the system having one or more stored network addresses for each of a plurality of communication identifiers;
determining one or more network addresses for the target endpoint from the stored network addresses associated to the communication identifier;
and
applying one or more policies to the one or more network addresses for the target endpoint to route the message through the firewall based on the determined one or more network addresses and one or more actions defined in the applied one or more policies, wherein applying one or more policies to the one or more network addresses for the target endpoint comprises changing the at least one of the one or more network addresses for the target endpoint based on one or more conditions defined in the applied one or more policies and producing a script comprising the one or more network addresses, a port address of an open port of the firewall, and instructions associated with each of the one or more network addresses, the instructions of the script comprising at least one condition and at least one action associated with each condition and affecting further routing of the message based on satisfaction of the associated condition.

1 more element

A Session Initiation Protocol (SIP) system for providing customized routing of messages, the system comprising:

a target endpoint;
an originating endpoint communicatively coupled with the target endpoint;
a firewall between the target endpoint and the originating endpoint;
and
a custom proxy communicatively coupled with the target endpoint and the originating endpoint and adapted to receive a message from the originating endpoint to the target endpoint, determine one or more target SIP Uniform Resource Identifiers (URIs) for the target endpoint from stored addresses of record and apply one or more policies to the one or more target SIP Uniform Resource Identifiers (URIs) for the target endpoint to route the message through the firewall, wherein applying the one or more policies comprises modifying at least one of the determined one or more target SIP URIs based on one or more conditions and one or more actions defined in the applied one or more policies and a port address of the firewall and wherein changing the one or more target SIP URIs for the target endpoint comprises producing a script of SIP URIs, the SIP URIs including a URI for an open port of the firewall and the script further comprising instructions associated with each of the SIP URIs, the instructions of the script comprising at least one condition and at least one action associated with each condition and affecting further routing of the message based on satisfaction of the associated condition.

A Session Initiation Protocol (SIP) system for providing customized routing of messages, the system comprising:

a target endpoint;
an originating endpoint communicatively coupled with the target endpoint;
a firewall between the target endpoint and the originating endpoint;
and
a third-party call controller communicatively coupled with the target endpoint and the originating endpoint and adapted to receive a message from the originating endpoint to the target endpoint, determine one or more target SIP Uniform Resource Identifiers (URIs) for the target endpoint from stored addresses of record and apply one or more policies to the one or more target SIP Uniform Resource Identifiers (URIs) for the target endpoint to route the message through the firewall based on the determined one or more target SIP URIs and one or more actions defined in the applied one or more policies, wherein applying one or more policies to the one or more network addresses for the target endpoint comprises changing at least one of the one or more target SIP URIs for the target endpoint based on one or more conditions defined in the applied one or more policies and producing a script comprising the one or more SIP URIs, the SIP URIs including a URI for an open port address of the firewall and the script further comprising instructions associated with each of the SIP URIs, the instructions of the script comprising at least one condition and at least one action associated with each condition and affecting further routing of the message based on satisfaction of the associated condition.
