...efine 'best' as the solution that is most likely to work without problems (like interupt conflicts) and work with my current echo tuning . I see my purchase options as follows: 1) TDM40B - use with the current TDM40B 2) Sangoma Remora A20200 - use with the current TDM40B 3) Sangoma Remora A20400 - replace the current TDM40B Any info will be greatly appreciated.
