System and method for providing spectrally efficient voice communication in wireless and satellite communication networks

A method comprising:

• providing a dedicated channel between a user terminal and a gateway;
• associating the dedicated channel of a voice communication with a header context;
• receiving an IP standard packet comprising a header and a voice payload from a terrestrial network device;
• selecting a selected dedicated channel from the dedicated channel based on an association between the header and the header context;
• updating the header context based on the header;
• and
• sending a packet comprising the voice payload over the selected dedicated channel, wherein the packet does not include the header.

A system comprising:

• a gateway;
• and
• a dedicated channel for voice communication connected to the gateway;
• wherein the gateway
• associates the dedicated channel with a header context,
• receives a packet comprising a voice payload of the voice communication over the dedicated channel, wherein the packet does not include the header context,
• selects an associated header context based on the dedicated channel,
• generates a header based on the header context, and
• sends an IP standard packet comprising the header and the voice payload to a terrestrial network device.
