DMV1200 Detects 33 voice boards instead of 30 , what are extra boards and channels ?

  • I have a DMV1200 board, I get Voice Board counts with   sr_getboardcnt("Voice", &BoardCount); 

    It returns 33 voice boards , with total of 132 voice channels.

    as DMV1200 is 120 channel , I expect to open 120 voice channels so what are extra 12 channels for?

    Should I open first 120 voice channels ? How and when should I use extra channels ?

  • Pending the mediaload you are using they are probably fax channels in this case.

    You can confirm by running devmapdump from DOS CMD prompt and you will see those devices have assigned fax addr.

    Yes I saw in devmapdump and they are Fax Channels.
