ABSTRACT:
A method and system are provided for enabling packet-based tandem free operation C(FO). In one example, the method includes monitoring packets sent between network elements to identify a TFO request message and a TFO acknowledgement message. A substitute TFO acknowledgement message is sent from an intermediate network element if no TFO acknowledgement message is identified, and both TFO and non-TFO call legs may be established.
