With dialers, it's the cps that is causing issues (the calls are very short). Actually, both cps and channel limitation can be implemented simultaneously (via ratelimit and dialog module). The burden on the server is not high even at high cps (>150cps) with channel limitation in place (i.e. dialog profiling enabled).
