hey guys i am getting busy signals for some agents when they try to go grab a line to dial out. i ran a li measurements tone-receive detail today-peak and i see that "type" tdmf has "pn req" of 4980 and "pn alloc" of 2750 and "peak alloc" of 8. Is this what is causing the busy signals and if so what card is responsible for the dtmf tones and how do i allocate more. thanks.
