CHAPTER 2. MMC Programming2-270 © SAMSUNG Electronics Co., Ltd.[726] VM/AA OPTIONSThis MMC is used to define all the in-band DTMF (Dual Tone Multi-Frequency) codessent to voice mail ports.These in-band codes can be 0-9, A, B or C, and perform two functions:CALL AND TYPE INFORMATIONThis is a DTMF Signaling string sent to a voice mail port when the voice mail port answersa call. This DTMF information tells the voice mail port what type of call it is receiving andwhere the call is coming from. (e.g., call forwarded from extension 225)CALL PROGRESS TONESThese are sent to the voice mail system to provide information about the progress of thecall. (e.g., ring back, busy or disconnect) Most voice mail systems can use DTMF in-bandSignaling for more efficient call processing. This MMC has many parameters that can beprogrammed according to the type of automated attendant and/or voice mail systemconnected.CALL and TYPE INFORMATIONThe format of the DTMF data sent to a VM/AA port is as follows:[CALL TYPE] + [DN1] + [SEPARATOR] + [DN2]An example of this would be:[FORWARD ALL] from [225] on trunk [703]Each field can be programmed individually as follows:Option Description DefaultEXTENSIONFOR DN1If set to yes, when the voice mail auto attendant system answersa call the system will send data in the DN1 field indicating that astation is ringing the VMAA port.If set to no, when the voice mail auto attendant system answersa call the system will not send station data in the DN1 field.NoTRUNK FOR DN1 If set to yes, when the voice mail auto attendant system answersa call the system will send data in the DN1 field indicating that atrunk is ringing the VMAA port.If set to no, when the voice mail auto attendant system answersa call the system will not send trunk data in the DN1 field.NoEXTENSIONFOR DN2If set to yes, when the voice mail auto attendant system answersa call the system will send data in the DN2 field indicating theoriginating station of the call ringing the VMAA port.If set to no, when the voice mail auto attendant system answersa call the system will not send station data in the DN2 field.No
