[Asterisk-Users] How to delay dialing

[Eric Wieling]

Set the DTMF mode to be the same on the SIP device and on Asterisk.  In
Asterisk it's dtmfmode=rfc2833 in the [sipdevice] section of sip.conf. 
BOTH Asterisk and the SIP device need to be set to the same DTMF mode. 
If the phone is sending inband DTMF and Asterisk expects rfc2833 DTMF
it's not going to work right.  If you are using inband DTMF and a
compressed codec (basically any codec other than G711 ulaw or G711 alaw)
then DTMF will not work right.  The codec will distort continuous tones.
You MAY have to set the DTMF mode to "info" on Asterisk and the SIP
device.  Reports on this vary.
