I used this instruction https://docs.retellai.com/deploy/telnyx (the Telnyx interface now looks a little different) but got SIP/2.0 486 Rejected. Then I tried this video https://docs.retellai.com/deploy/custom-telephony but still got SIP/2.0 486 Rejected. Also I tried to use

sip.retellai.com

and

5t4n6j0wnrl.sip.livekit.cloud

as FQDN. These documentations are a little bit different but I think I tried all ways. In the Retell interface I don't see any calls or call logs. https://cdn.discordapp.com/attachments/1461669522607046742/1461669522951110768/Screenshot_2026-01-16_at_11.31.23.png?ex=6979e5d2&is=69789452&hm=4bdee43e98a374a44504552b7dca879a8767c577a4ded35914696d80110bc473& https://cdn.discordapp.com/attachments/1461669522607046742/1461669523601101004/Screenshot_2026-01-16_at_11.31.29.png?ex=6979e5d2&is=69789452&hm=c0252d6df2148ca30101a5d771e5c64eec80e370e096469c38c5a4540b28fcb7&

hello

yes

ok share me Telnyx call logs

I can't replace

sip.retellai.com:null

🙁 telnyx does it automatically, I can just delete primary FQDN

ok also send me screen short of "Authentication and Routing" and number tab

sorry plases reshare the pcap file

+18779050071 Is this the exact number imported in Retell and make sure imported number is assigned to inbound agent

omg, thank you, my fault I put nickname into phone number field

No problem some time it happens
