Description
The option to send DTMF audio tones in the RTP
stream for SIP calls.
The options are:
• RFC2833: This is the default option.
• SIP INFO
Select Yes to send DTMF tones in this way for H.323
calls. By default, this is standard for SIP calls and
disabled for H.323 calls, since not all H.323 devices
are compatible with this format. To enable, the remote
H.323 endpoint must also support RFC2833.
Select Yes (default) to enable out-of-band DTMF
transmissions in H.323 calls. Select No if you
deployed some legacy H.323 equipment which does
not support out-of-band DTMF.
Select Yes to enable the H.323 application uses a
generic vendor code identity instead of its default
vendor code. So, the remote H.323 devices do not
recognize it as an Avaya endpoint.
