Release link trunking for IP telephony
First Claim
1. A method for performing release trunking for calls originating and terminating outside of an IP address space, the method comprising:
- establishing a call from an originator in a first address space outside of the IP address space to an IP device within the IP address space;
sending, from the IP device, a message to a switch in the first address space indicating a new destination in the first address space;
releasing the established call from the IP device, such that resources of the IP device are not used for a call from the originator in the first address space to the new destination in the first address space; and
establishing a second call from the originator in the first address space to the new destination in the first address space.

Abstract
Methods and systems are provided that use resources more efficiently for calls originating and terminating in a first address space that use services in an IP address space. A call is established from an originator in a first address space to an IP device within an IP address space. The IP device sends a message to a switch in the first address space indicating a new destination in the first address space. The established call is released and a second call is established from the originator in the first address space to the new destination in the first address space. In another implementation, a first leg of a call is established to an IP device from a first address space. The IP device establishes a second leg of a call to a destination in the first address space. The calls are bridged and resources released.

11. A method for bridging calls, comprising:
-
establishing a first leg of a call originating from a first address space to an IP device in an IP address space; establishing a second leg of a call originating from the IP device in the IP address space to the first address space; bridging the first leg of the call and the second leg of the call; and releasing the first and the second legs of the call from the IP device, such that resources of the IP device are not used for the bridged call. - View Dependent Claims (12, 13, 14, 15, 16)

17. A system for performing release trunking for calls originating and terminating outside of an IP address space, comprising:
-
a gateway configured to send and receive messages using a first protocol in a first address space and to send and receive messages using a second protocol in the IP address space; and an IP device located within the IP address space and configured to communicate with the gateway, the IP device being further configured to send a first message to the gateway requesting that a call be setup between an originator in the first address space and a destination in the first address space, an indicator for the destination being included in the first message and being based on information received over an established call to the IP device from the originator, and the gateway being further configured to; request resources of the established call to be released, such that resources of the IP device are not used for a call from the originator in the first address space to the destination in the first address space, translate the first message in the first protocol to a second message in the second protocol, and send the second message to a device in the first address space. - View Dependent Claims (18, 19, 20, 21, 22)

23. A tangible computer-readable medium that stores instructions executable by one or more processors to perform a method for release trunking for calls originating and terminating outside of an IP address space, the computer-readable memory device comprising:
-
instructions for receiving a request for a call to an IP device from a device in a first address space; instructions for saving an indication of an originator of the call; instructions for translating the request for the call from a first protocol to a second protocol and sending the request in the second protocol to the IP device; instructions for receiving from the IP device a message in the second protocol requesting a second call be established to a new destination; instructions for translating the message requesting the second call to the first protocol and inserting the indication of the originator into the message; instructions for sending the message into the first address space; and instructions for releasing the IP device from the call such that resources of the IP device are not used for a call from the device in the first address space to the new destination in the first address space. - View Dependent Claims (24, 25, 26)
