My attempts to use voice mail from my Grandstream Budgetone 101 phone always fail because Asterisk is seeing either double digits or dropped digits, no matter what dtmfmode setting I try. Here is what happens for each mode:
dtmfmode=info, phone set to send INFO 101: every digit is seen double, e.g. 123 is seen as 112233 dtmfmode=rfc2833, phone set to RFC2833: some digits are doubled in random places, e.g., 123 is sometimes seen as 1123, sometimes as 1233 dtmfmode=inband, phone set to send in-audio: some digits are dropped, e.g., 123 becomes 23 or 12 I have upgraded the firmware in my phones to 1.0.4.46 and Asterisk is a CVS from 2/1/04. The codec in the phones is set to PCMU (ulaw) as first preference, and the sip.conf has disallow=all followed by allow=ulaw for each phone. Early dial is turned off. Can anyone help me? Thanks, -Ron
