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.
