Cisco SPA 500 Series and Wireless IP Phone Field Reference Ext Tab B Parameter Release Unused Codec DTMF Process AVT Silence Supp Enable DTMF Tx Method DTMF Tx Volume for AVT Packet Description Allows the release of codecs not used after codec negotiation on the first call so that other codecs can be used for the second line. To use this feature, select yes. Defaults to yes. Select yes to process RTP DTMF events. Otherwise, select no. If this parameter is set to no, the AVT payload type is not included in outbound SDP. Defaults to yes. To enable silence suppression so that silent audio frames are not transmitted, select yes. Otherwise, select no. See Ensuring Voice Quality, page 114. Defaults to no. Select the method to transmit DTMF signals to the far end: InBand, AVT, INFO, Auto, InBand+INFO, or AVT+INFO. InBand sends DTMF using the audio path. AVT sends DTMF as AVT events. INFO uses the SIP INFO method. Auto uses InBand or AVT based on the outcome of codec negotiation. Defaults to Auto. Allows you to manually configure the AVT Tx volume. The value of this parameter is inserted into the volume field of the payload in the AVT packet. Values are based on the AVT specification as described in RFC 2833, RTP Payload for DTMF Digits, Telephony Tones and Telephony Signals. According to RFC 2833, the volume field is represented by 6 bits, and describes the power level of the tone, expressed in dBm0 after dropping the sign. Valid range for this parameter is 0 to 63. If the provisioned value is negative, it will be negated first. Thereafter, if the value is beyond the high limit of 63, it will be clipped to 63. The default value is 0, and is the recommended setting. However, some gateways do not accept this volume setting. If the gateway does not accept the value of 0, the DTMF tone is not relayed to the remote end. As a workaround for the phone to interoperate with those gateways, you can change the value to a value greater than 0. Cisco SPA 500 Series and WIP310 IP Phone Administration Guide 277

Release Unused Codec

Allows the release of codecs not used after codec

negotiation on the first call so that other codecs can be

used for the second line. To use this feature, select yes.

Defaults to yes.

DTMF Process AVT

Select yes to process RTP DTMF events. Otherwise,

select no. If this parameter is set to no, the AVT

payload type is not included in outbound SDP.

Defaults to yes.

Silence Supp Enable

To enable silence suppression so that silent audio

frames are not transmitted, select yes. Otherwise,

select no. See

Ensuring Voice Quality, page 114

Defaults to no.

DTMF Tx Method

Select the method to transmit DTMF signals to the far

end: InBand, AVT, INFO, Auto, InBand+INFO, or

AVT+INFO. InBand sends DTMF using the audio path.

AVT sends DTMF as AVT events. INFO uses the SIP

INFO method. Auto uses InBand or AVT based on the

outcome of codec negotiation.

Defaults to Auto.

DTMF Tx Volume for AVT

Packet

Allows you to manually configure the AVT Tx volume.

The value of this parameter is inserted into the volume

field of the payload in the AVT packet.

Values are based on the AVT specification as

described in RFC 2833,

RTP Payload for DTMF Digits,

Telephony Tones and Telephony Signals

. According to

RFC 2833, the volume field is represented by 6 bits,

and describes the power level of the tone, expressed

in dBm0 after dropping the sign.

Valid range for this parameter is 0 to 63. If the

provisioned value is negative, it will be negated first.

Thereafter, if the value is beyond the high limit of 63, it

will be clipped to 63.

The default value is 0, and is the recommended setting.

However, some gateways do not accept this volume

setting. If the gateway does not accept the value of 0,

the DTMF tone is not relayed to the remote end. As a

workaround for the phone to interoperate with those

gateways, you can change the value to a value greater

than 0.
