2.13 DTMF
This group of settings configures Bria to handle DTMF. DTMF can be sent in one of these ways:
• Out-of-band using DTMF 2833 packets
• Via SIP INFO
• In-band: Bria will encode the DTMF signals in the audio stream as regular sound.
• Out-of-band using DTMF 2833 and via SIP INFO
• In-band and via SIP INFO
To configure DTMF, set the desired settings to true. Do not set both inband and outofband to true; if you do, the
inband setting will be ignored. If you set all three settings to 0, DTMF will not be sent at all.
The preferred DTMF method is out-of-band.
In-band is used only to deal with specific network situations. For example:
• One scenario in which it might be advisable to send in-band is if you own your gateways and:
• One or more of these gateways does not support 2833 or does not handle it well, and
• Your gateway is using codes that reproduce DTMF tones well.
In this case, sending in-band will ensure that DTMF tones get through (because the DTMF tones will
bypass the gateway) and that they reproduce accurately at the receiving end.
• Another scenario is:
• One or more of these gateways does not support 2833 or does not handle it well.
• Your gateway is using codecs that do not reproduce DTMF tones well (because they are designed to
handle human voice rather than artificial sounds).
In this scenario, using in-band will not help ensure DTMF ones get through. There is in fact no solution in
this scenario.
