DTMF
DTMF Control how the MAX208M2W Series handles the tones that the phone
using this extension makes when you push its buttons. One use of the
tones is to distinguish between numbers when trying to dial a PSTN
phone number.
You should use the same mode as your VoIP service provider. The
choices are:
• Out-of-band(RFC 2833) - Follow the RFC 2833 standard and send
the DTMF tones in RTP packets.
• In Band - Send the DTMF tones in the voice data stream. This
works best when you are using a codec that does not use compression
(like G.711). Codecs that use compression (like G.729) can distort the
tones.
SIP INFO Select this to have the MAX208M2W Series send the DTMF tones in
