Where it sits in an outbound stack

Most outbound stacks are four layers: the data that decides who you talk to, the channel that carries the message, the writing that earns a reply, and the system of record that remembers what happened. KrispCall sits in the phone dialers layer. Tools beside it are worth comparing on coverage and price; tools in the other layers are worth wiring to it rather than replacing it with.
