Silence suppression: Endpoints sending audio as and RTP stream are not required to send packets during silent periods. The capability to stop sending RTP packets during silent periods is known as ‘silence suppression’.
A component of a voice gateway or terminal that suppresses the packetization of voice signals between individual speeches utterances, such as during the silent periods in a voice conversation. VADs generally operate on the send side of a gateway and can often adapt to varying levels of noise versus voice
CNG: During periods of transmit silence, when no packets are sent, the receiver has a choice of what to present to the listener. Muting the channel gives the listener the unpleasant impression that the line has gone dead. A receive-side CNG generates a local noise signal that it presents to the listener during silent periods.
Echo canceller: Echo cancellers are devices that attempt to reduce the volume of an echo to make it less annoying.
DTMF via RTP: DTMF via RTP, which send DTMF tone on the voice. It has two types which are by using RFC 2833 that creates the tone with data, and by using In-Audio that sends the direct tone from the phone.
DTMF Payload Type: The DTMF number set when placing a call can be changed. If a Gateway using different DTMF number from 101, this can be changed on this menu.
Option: SRTP is used as an optional item. If a Gateway does not support SRTP, this will be connected to previous RTP.
Mandatory: SRTP is used as a mandatory item. Thus, if any equipment does not support SRTP, It will not be able to place a call.
SRTP setting: On this menu, phone’s SRTP can be set as below setting.
DTMF via SIP: In this mode, DTMF tone is created in accordance to SIP protocol standard. Normally, this tone is created in the Gateway which is connected to PSTN through the service server. It can be used if the VoIP server supports this service.
DTMF-Relay: to use DTMF type as DTMF –Relay method.
DTMF: to use DTMF type the same as Cisco setting format.

setting. After change the setting, reboot the phone to apply the setting.
INFO DTMF type: The SIP INFO method can be used by SIP network elements to transmit DTMF tones out-of-band as telephone-events in a reliable manner independent of the media stream.
DTMF: Dual Tone Multi Frequency, a system used by tough tone telephones. DTMF assigns a specific frequency (consisting of two separate tones) to each key so that it can easily be identified a microprocessor.
Preferred CODEC
This is the feature to change the sound to packet. Voice quality and traffic are determined by preferred Codec type. IP250 supports four types; uLaw, aLaw, 729A, and 729B so that you can choose preferred Codec and put a priority. For setting this priority, follow company network manager’s commend.
