## Abstract

An architecture and method is provided for call routing using both IMS and non-IMS frameworks. The method includes receiving presence information of a third party from a non-IP Multimedia Subsystem (IMS) network device. The method further includes routing the third party to at least one callee designated device based on configurable preferences provided by the callee and correlated to presence information using an IMS compliant component. The method additionally includes providing a charging record for the routing on an IMS complaint charging platform.

## Claims

### Claim 1

A system for call routing applications, comprising:
a computer infrastructure being operable to:
route presence information of a third party from both non-IMS network devices and IMS network devices to IMS compliant presence components;
route the presence information of the third party received from the non-IMS network devices and IMS network devices to a callee based on configurable preferences provided by the callee and correlated to the presence information on the IMS compliant presence components;
send charging information for the routing to an IMS compliant charging platform associated with the IMS compliant presence components,
wherein:
the configurable preferences specify at least one delivery channel to transmit the presence information of the third party;
the presence information includes a notification of an availability of the third party on a particular communication channel; and
the particular communication channel is in the IMS network or in the non-IMS network.

### Claim 2 (depends on 1)

The system of claim 1, wherein the computer infrastructure is at least one of supported, deployed, maintained, and created by a service provider.

### Claim 3 (depends on 1)

The system of claim 1, wherein the steps are provided on a software component, a hardware component or a combination of the software component and the hardware component.

### Claim 4 (depends on 1)

The system of claim 1, wherein the presence information is received by a feature server using the SIP based notification and is published prior to receiving a call.
