Maybe you should add OTLP support? I don’t know how you are ingesting from Fluentbit at the moment, but I think with OTLP basically any log source can be integrated either through the fluentbit OTLP plugin or an OTEL collector.

What? SMS is a proven standard that works reliably. Why do we need to replace that? I tried RCS twice, in both cases the other end did not receive my message or at a later time. Even if SMS needed replacement, RCS is not it.
