Abstract:
1. A method comprising: establishing a first voice connection between a first calling device and a first called device, wherein a server establishes the first voice connection using a first codec of a first type after identifying itself as supporting (i) only the first type of codec and (ii) no codec translation; and establishing a second voice connection between a second calling device and a second called device, wherein the server establishes the second voice connection using a second codec of a second type after identifying itself as supporting (i) only the second type of codec and (ii) no codec translation; wherein the first type of codec is associated with a first signal format, and wherein the second type of codec is associated with a second signal format that is different than the first signal format, and wherein, when each of the first voice connection and the second voice connection is to be established, identifying itself as supporting only one type of codec and no codec translation relieves the server of the burden of performing codec translation.
