the max is controlled by the number of channels times the number of broad cast.. you have one unique recording per channel active at a time.. i have more voice files then i do channels.. i can change to recording by changing the file name on that card via the menu.. if i need more them 8 rans and or 8 moh channels total, i would need a second miran.. i have 16 channels, 5 for moh, again i would only need one for an 11.. i could change music on hold from the screen..
why are you thinking you want more then one music channel?
