Digium VPM64M Echo Cancellation Module
The VPM64M provides high quality echo cancellation to combat echo on a T1/E1 interface.
Though there are open source echo cancellation routines that are somewhat effective in eliminating this hybrid type echo, the Digium VPM64M module resolves this problem in hardware, mitigating any negative effect CPU resource shortages may induce on an otherwise purely software based echo cancellation solution.
