Hi, Am facing with a typical issue. In my phone settings, if i enable 'Force RFC2833 Out-of-Band DTMF' then my voicemail is not working properly( If I record any greeting or VM, only part of the message is being recorded) but offnet calls for banks or shops is working. If 'Force RFC2833 Out-of-Band DTMF' is disabled my voicemail is working properly but When I call offnet numbers like Banks or shops, then my key press is not being recognised i.e no DTMF detection. My internal .xml and external settings for DTMF is <param name="dtmf-type" value="rfc2833"/> <param name="rfc2833-pt" value="101"/> <param name="dtmf-duration" value="2000"/> Please let me know what needs to be changed so that both voicemail and offnet numbers work properly. Regards, Archana
