Enabling Individual Codecs
Enabling individual codecs allows you to define codecs that can be considered during negotiation. If codecs
are disabled, they are not considered.

To enable voice codecs:
1.
In the
voiceIfMIB,
choose the codec you want to use (
voiceIfCodecTable
).
You have the choice between the following codecs:
2.
If you have enabled one or more of the G.726 codecs, set the G.726 actual RTP dynamic payload
type used in an initial offer in one or more of the following variables:
•
voiceIfCodecG72616kbpsPayloadType: The default value is 97.
•
voiceIfCodecG72624kbpsPayloadType: The default value is 98.
•
voiceIfCodecG72632kbpsPayloadType: The default value is 99.
•
voiceIfCodecG72640kbpsPayloadType: The default value is 100.
The payload types available are as per RFC 3551. The values range from 96 to 127.
3.
If you have disabled or enabled the G.723 and/or G.726 codecs, you must restart the Mediatrix
1204.

Note:
When selecting the dynamic payload type, make sure that the value is not already used by another
dynamic codec. If a value between 96 and 127 is refused, this means it is already used by another dynamic
codec.
Note:
If you set the
voiceIfDtmfTransport
variable to
outOfBandUsingSignalingProtocol
(
), you cannot configure a dynamic payload type to 111 because it is already
used by the DTMF out-of-band using signalling protocol.
Caution:
The Mediatrix 1204 cannot use G.723 and G.726 at the same time due to memory size limitation.
You must restart the Mediatrix 1204 when enabling or disabling these two codecs. If both G.723 and G.726
are enabled when you restart the Mediatrix 1204, G.723 is the codec used.
