CRS provides a variety of modalities: Modal ties are the type of service used based on the communication needs of the call parties.

Federal regulations specify very strict confidentiality requirements for CAs of all relay services. No part of the conversation that takes place between callers is revealed or recorded in written, verbal, or any other form. CRS CAs do not participate in the conversation and acquire no benefit from information relayed.
