As expalined in the previous post, SMDI messages are a set of ASCII characters and symbols so we can easily understand the structure of the messages.<\/p>\n

Direct Calls<\/span><\/em><\/p>\n

<CR><LF> MD “md-num” “md-port” “fwd-type”<0X20>”src-num”<0x20><CR><LF><^Y><\/p><\/blockquote>\n

Here is the explanations of all elements<\/p>\n

\n
    \n
  • <CR> : Carriage Return<\/li>\n
  • <LF> : A Line Feed<\/li>\n
  • MD “md-num” “md-port” : Message Desk Number (usually 001) and Message Desk Port (a port between 0000 and 9999)<\/li>\n
  • Forward-type : Indicates the forwarding type, D is a direct call<\/li>\n
  • <0X20> : ASCII space<\/li>\n
  • “src-num” : the number of the station from which the call originated (ANI)<\/li>\n
  • <^Y> : Control Y<\/li>\n<\/ul>\n<\/blockquote>\n

    Forwarded Calls<\/em><\/span><\/p>\n

    <CR><LF> MD “md-sum” “md-ports” “fwd-type” “fwd-station”<0X20>”src-num”<0X20><LF><^Y><\/p><\/blockquote>\n

    So the new fields are<\/p>\n

    \n
      \n
    • “fwd-type” : As previously mentionned, this indicates the forward type but in this case, the type can be A (All cals), B ( Busy), N (No-Answer) or U (forwarded for unknown reason)<\/li>\n
    • “fwd-station” : The RDNIS (original called party number)<\/li>\n<\/ul>\n<\/blockquote>\n","protected":false},"excerpt":{"rendered":"
