Internet telephony signal conversion
First Claim
Patent Images
1. A method of processing, at a voice processing gateway system, an internet telephony message comprising voice data said method comprising the steps of:
- receiving said message in accordance with the Internet Protocol at said gateway system in a first internet telephony format from a first computer connected to the internet;
performing on a digital signal processor channel at said gateway system a first conversion of the message from the first internet telephony format to an intermediate format in conformity with the internal processing of said gateway system;
performing on an adjacent digital signal processor channel at said gateway system a second conversion of the message from the intermediate format to a second format said second format being a different format to said first format whereby said second conversion is not a conversion back to said first format but a conversion to a format different to said first format;
sending from said gateway system in accordance with the Internet Protocol the message in the second format to a second computer connected to the internet.

Abstract
The disclosure concerns a method of processing Internet telephony messages at gateway computer such as an IBM RISC/6000 system, comprising the steps of: receiving an Internet telephony message in a first compression scheme from a computer running an Internet telephone software application which uses the first compression scheme; converting the Internet telephony message into a compression scheme optionally via an intermediate format; sending the Internet message telephony to another computer running another Internet telephone software application using the second format.

1. A method of processing, at a voice processing gateway system, an internet telephony message comprising voice data said method comprising the steps of:
-
receiving said message in accordance with the Internet Protocol at said gateway system in a first internet telephony format from a first computer connected to the internet;
performing on a digital signal processor channel at said gateway system a first conversion of the message from the first internet telephony format to an intermediate format in conformity with the internal processing of said gateway system;
performing on an adjacent digital signal processor channel at said gateway system a second conversion of the message from the intermediate format to a second format said second format being a different format to said first format whereby said second conversion is not a conversion back to said first format but a conversion to a format different to said first format;
sending from said gateway system in accordance with the Internet Protocol the message in the second format to a second computer connected to the internet. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
identifying the internet telephony format of the first computer; and
selecting an appropriate algorithm from a plurality of conversion algorithms to perform said first conversion.

21. A voice processing gateway system for processing an internet telephony message, said message comprising voice data said system comprising:
-
means for receiving said message in accordance with the Internet Protocol in a first internet telephony format from a first computer connected to the internet;
means for performing on a digital signal processor channel a first conversion of the message from the first internet telephony format to an intermediate format in conformity with the internal processing of said gateway system;
means for performing on an adjacent digital signal processor channel a second conversion of the message from the intermediate format to a second internet telephone format said second format being a different format to said first format whereby said second conversion is not a conversion back to said first format but a conversion to a format different to said first format; and
means for sending in accordance with the Internet Protocol the message in the second format to a second computer connected to the internet. - View Dependent Claims (22)
a plurality of conversion algorithms for converting an internet telephony message from one of a plurality of formats to said intermediate format;
means for identifying the internet telephony format of the first computer and selecting the appropriate algorithm to perform the first conversion; and
means for identifying the internet telephony format of the second computer and selecting the appropriate format to perform the second conversion.
