I currently have one incoming T1 based NI2 PRI which terminates into an Adtran Atlas which then generates two network-side PRIs. The Atlas routes incoming calls between the two network-side PRIs based on DID numbers. I want to remove the Atlas from service and move this functionality to my 2821 router. My 2821 has the VWICs to do this but no DSP modules and I'm hung up on what I really need re DSPs. Since I currently don't want any call to end terminate on the 2821, do I need DSPs modules? All PRI switching configuration examples I've read involve some sort of VoIP operation which I don't need to deal with right now.
It doe not matter which type of call it is, you still need DSP for the simple fact you are configuring a voice interface.
