For a predictive outbound system with 20 agents you would want to have about 30-40 channels used for the outgoing legs of the calls in addition to the 20 channels that would connect calls to agents. So about 50-60 channels all up.
The connected calls would be routed through VoiceGuide which would let you record the calls and use other automation featured like playing pre-recorded sound files to customers if agent presses a key (or series of keys, or a button on their popup window etc) on their keypad.
Same amount of HMP licenses.
Please contact email@example.com for HMP license pricing. HMP licenses need to be purchased through us so that we may support the system properly.
