Resource-managed codec selection

One or more non-transitory computer storage media with a stored computer-executable program, which, when executed by one or more processors of a first device, performs actions comprising:

• receiving a request for an audio call between a first audio terminal and a second audio terminal, wherein the first audio terminal supports a first codec and a second codec;
• determining that the second codec will be used in communicating audio of the audio call with the second audio terminal;
• determining that there is at least a threshold level of computational resources available for audio data stream transcoding;
• and
• in response to determining that there is at least a threshold level of computational resources available for audio data stream transcoding:
• (a) causing the first codec to be used in communicating audio of the audio call with the first audio terminal;
• and
• (b) transcoding an audio stream of the audio call using the first codec and the second codec.

One or more devices, comprising:

• one or more processors;
• one or more non-transitory computer-readable media storing computer-executable instructions that, when executed on the one or more processors, cause the one or more processors to perform actions comprising:
• receiving a request to anchor a session between a first communication terminal and a second communication terminal, wherein the first communication terminal supports a first codec and a second codec;
• determining that the second codec will be used for media communications with the second communication terminal;
• determining that there is at least a threshold level of computational resources available for media stream transcoding;
• in response to determining that there is at least a threshold level of computational resources available for media stream transcoding:
• (a) causing the first codec to be used for media communications with the first communication terminal;
• and
• (b) transcoding a media stream of the session using the first codec and the second codec.
