Hi All, I am having Problem in detecting DTMF on analog lines. basically are system is in india and telco provider is BSNL [Bharat sanchar Nigam LImited]. We have Purchased Analog card From chinaroby.com which is X1600P 16 port FXO card. they also provide us wctdm.c file. card is detected successfully, incoming and outgoing calls scenario is also fine. we are unable to receive dtmf properly it means there is some digit are missing when we receive dtmf the ratio of sucess is about to 70% and 30% of calls are getting wrong dtmf . Dahdi version is 2.3.0.1 and asterisk version 1.6.0.24 I load module using modprobe wctdm opermod=INDIA cidbeforering=1 cidbuflen=1 fixedtimepolarity=16 here id chan_dahdi.conf.
