Abstract

In some embodiments, two or more packets of a first protocol including data of a real time protocol (RTP) which is associated with audio and/or video conferencing information may be received at a first interface. Two or more data channels may couple the first interface to a second interface via various networks, and each of the two or more data channels may include network sockets of a second protocol. Any number of N data channels may be used based on various configurations. The two or more packets of the first protocol may be sent from the first interface to the second interface via the two or more data channels. In various embodiments, a first RTP may be received and transcoded into a second RTP, and data from a first codec associated with the first RTP to data of a second codec associated with the second RTP.

Claims

receiving a plurality of packets of a first protocol at a first interface, wherein the plurality of packets of the first protocol comprise data of a real time protocol which is associated with audio and/or video conferencing information;

determining a first data channel of a plurality of data channels of a second protocol;

transmitting a first packet of the plurality data packets of the first protocol via the determined first data channel to a second interface;

determining a second channel of the plurality of data channels of the second protocol; and

transmitting a second packet of the plurality data packets of the first protocol via the determined second data channel to the second interface;

wherein each of the plurality of data channels couples the first interface and the second interface via a network.

2. The method of claim 1, wherein the real time protocol comprises one or more of session initiation protocol (SIP), H.261, H.263, H.264, and H.323.

3. The method of claim 1, wherein the first protocol comprises a user datagram protocol (UDP).

4. The method of claim 1, wherein a service provider is coupled to the second interface.

5. The method of claim 1,

wherein the first interface and the second interface are coupled through a gateway, and

wherein the gateway comprises one or more of a firewall, a packet filter, and a network address translation mechanism.

6. The method of claim 5, wherein the gateway is configured to block the first protocol.
