Patent Images
1. A method for connecting a call between a calling party and a called party, comprising:
- translating a first source address into a first global address, the first source address being local to a first network and being associated with the calling party;
translating a first destination address into a second global address;
sending the first global address and the second global address from a first network edge device to a second network edge device, the first network edge device connecting the first network and a second network, the second network edge device connecting a third network to the second network, the third network being associated with the called party;
translating the first global address into a second source address, the second source address being local to the third network;
translating the second global address into a second destination address, the second destination address being local to the third network and being associated with the called party.

Abstract
A call between a first network associated with a calling party and a second network associated with a called party is connected. The source address for packets associated with the call arc translated. The packets are sent from the calling party to the called party without the called party receiving the source address that indicates at least one from the group of a logical identity of the calling party and a geographical identity of the calling party.

22. A method for connecting a call between a calling party and a called party, comprising:
-
receiving, from a first network edge device at a second network edge device, a first global address that is a translation of a first local address, the first local address being associated with a first network, the first network edge device connecting the first network and a second network, the second network edge device connecting a third network to the second network; and
translating the first global address into a second local address, the second local address being associated with the third network. - View Dependent Claims (23, 24, 25, 26)
