SIP 408 on Ohio BYOC failover trigger

Trying to get outbound traffic routing through the Ohio BYOC trunk group. Architect v2024.3.1 is running the show. The SIP stack’s throwing a 408 right when the failover logic kicks in.

{
 "status": 408,
 "trunk": "ohio-byoc-primary",
 "error": "SIP transaction timer expired",
 "keepalive_status": "dropped"
}
