dtmfmode=auto in my sip.conf, but that does not work and I still got the
following message:</FONT></DIV>

<DIV><FONT face="Courier New" size=2>WARNING[4980]: dsp.c:1422 ast_dsp_process:
Inband DTMF is not supported on codec g729. Use RFC2833</FONT></DIV>

<DIV><FONT face="Courier New" size=2>auto: Asterisk will use rfc2833 for DTMF
relay by default but will switch to inband DTMF tones if the remote side does
not indicate support of rfc2833 in SDP. This feature was added in CVS HEAD on
Sep 6 2005 and is not available in Asterisk 1.0.x. <BR></FONT></DIV>
<DIV><FONT face="Courier New" size=2>Why does it not work as the wiki
said?</FONT></DIV>
