Description
If the SIP trunk device does not support the codec capability sets
supported by the calling and called parties, you can select the
Enable option to enable codec transparent transfer on the SIP trunk
device. The SIP trunk device transparently transfers codec capability
sets between two parties. The calling and called parties complete
the codec negotiation.
By default, the Disable option is selected.
In the scenario where the SIP trunk device controls the results of
media capability negotiation, if the SIP trunk device cannot find a
common codec for two parties during negotiation, the two parties
will fail to establish a call. In this case, you can select the Enable
option to enable codec transcoding on the SIP trunk device.
With this function enabled, the SIP trunk device uses its own codec
capability set to negotiate with the calling and called parties
respectively. If the negotiated codecs with the two parties do not
match, the SIP trunk device transcodes the media flows passing
through it.
By default, the Disable option is selected.
IMPORTANT:
The codec transcoding feature does not take effect in any of the
following cases:
•
Codec transcoding is enabled, but no DSP resources are
available for codec transcoding.
•
Codec transparent transfer is enabled.
•
Media flow-around is enabled.
