I want to delete my account because I've been unable to get my hardware SIP phone working with your service despite extensive troubleshooting, and it doesn't work for my use case

Technical context: I spent a long time trying to get a Yealink T21P_E2 desk phone working against my LiveKit SIP trunk (*************.sip.livekit.cloud). Registration works fine over TLS/5061, but every outbound call from the phone goes out over plain UDP/5060 no matter how the account is configured — and your trunk doesn’t respond on UDP/5060 at all (confirmed via packet capture, zero replies either way). Network path itself is fine — TCP to port 5061 connects cleanly, and the same phone works normally against other SIP providers. So it looks like a hard incompatibility between this phone’s outbound call behavior and a TLS-only, no-REGISTER trunk, not something fixable on my end.

Please proceed with the account deletion unless you can help me

I’m not familiar with Yealink, but it looks like your SIP contact header is pointing at a private IP address, so possibly there is some issue with NAT traversal.

I’m unable to delete your account myself, but if you DM me I can provide instructions if you would still like to proceed.
