Patent ID: 8619957

Claim:
A method, comprising: receiving a call; generating call data for the call subsequent to receiving the call; determining whether the call data can be forwarded along a call path; identifying whether the call shares a same automatic number identification (ANI) and a same dialed number identification service (DNIS) with another call in response to determining that the call data cannot be forwarded along the call path; generating an identifier in response to identifying that the call shares the same ANI and the same DNIS with the other call, wherein the generating comprises: selecting a new DNIS, from a DNIS pool of DNIS numbers, which is different from the same DNIS; and generating the identifier that includes the same ANI and the new DNIS; assigning to the call data the identifier that identifies the call data; forwarding the call along the call path without the call data; and storing the call data and the identifier at a device outside the call path.
