@CWilson - I believe @darryncampbell mentioned the signal issue won’t be fixed from the `full reconnect` PR as this might be separate issue. Check here - [Signal connection times out on the "v0 path" at agent join, forcing a fallback that adds 0.5–5s of call-setup latency - #31 by darryncampbell](https://community.livekit.io/t/signal-connection-times-out-on-the-v0-path-at-agent-join-forcing-a-fallback-that-adds-0-5-5s-of-call-setup-latency/1377/31)

I am sure there must be some confusion. Can you please help clarify the PR - [fix: escalate to full reconnect if connection failed during a resume by davidzhao · Pull Request #1175 · livekit/rust-sdks · GitHub](https://github.com/livekit/rust-sdks/pull/1175) once released on agents side and when we upgrade will solve both the problems we are seeing wrt network issues:

1. The `signal connection failed` issue - this current post - [Signal connection times out on the "v0 path" at agent join, forcing a fallback that adds 0.5–5s of call-setup latency](https://community.livekit.io/t/signal-connection-times-out-on-the-v0-path-at-agent-join-forcing-a-fallback-that-adds-0-5-5s-of-call-setup-latency/1377)
2. The `Subscriber pc failed` - [Server-initiated migration fails to resume on agents 1.4.6 — subscriber + publisher PC fail, no recovery, process killed (expected fixed in \>1.4.2 per agents #4705)](https://community.livekit.io/t/server-initiated-migration-fails-to-resume-on-agents-1-4-6-subscriber-publisher-pc-fail-no-recovery-process-killed-expected-fixed-in-1-4-2-per-agents-4705/1440)

Would appreciate some clarity here.
