Hi Guys,
Would like to check, for my above router, currently I have a card which is connected to ISDN line
Would like to check this current pstn gateway if I add a few more card for a few more ISDN line is it possible?
My current ISDN is ISDN30 and it can support 30 concurrent call so if I add another 3 card for ISDN30 connection can this model 2921 support 120 concurrent call?
The specs seem a bit low, so would like to know if anyone have this setup before?
