We’ve introduced a new Outbound Declined Calls Dashboard in the Mission Control Portal to give self-service users deeper visibility into declined outbound traffic and help safeguard caller reputation.
Users can now track which telephone numbers (TNs) are generating high volumes of 603 (Decline) and 608 (Rejected) SIP responses, two common indicators of unwanted or problematic calling behavior.
The dashboard displays:
Trust and call completion are central to effective real-time voice experiences. High rates of 603 or 608 responses signal issues that can negatively impact answer rates, deliverability, and your long-term caller reputation. These responses usually occur when recipients decline a call (603) or when carriers/intermediaries reject calls for reputation or spam-related reasons (608).
By surfacing this information in a dedicated dashboard, Telnyx gives you more control over outbound traffic performance. This aligns with our broader mission to deliver a trusted, enterprise-grade telephony and voice AI platform built on owned, global infrastructure with compliance and reputation controls baked in from the network layer up .
With this dashboard, you can:
You can find the new dashboard in the Mission Control Portal under: Real-Time Communications > Voice > Reports > Outbound Declined Calls
From there, you can:
