ABSTRACT:
An approach provides interdomain traversal packetized voice transmissions. A request is received from a first endpoint of a first domain for establishing a communication session with a second endpoint of a second domain. A tunnel is established by a TURN (Traversal Using Relay NAT (Network Address Translation)) server to support the communication session. The TURN server is controlled by a service provider as part of a managed communication service. The tunnel traverses a first firewall and a first network address translator of the first domain and a second firewall and a second network address translator of the second domain to reach the second endpoint, wherein the communication session is encrypted and transported via the tunnel.
