Outbound Declined Calls Dashboard is Live

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:

• Total outbound call attempts
• Count and percentage of 603 and 608 responses
• A list of affected TNs with call counts per number
• Export to CSV for further analysis

Why it matters

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:

• Identify TNs associated with high decline or rejection rates
• Take proactive action by suppressing or adjusting usage of specific numbers
• Maintain compliance and reduce risk of spam classification
• Strengthen overall outbound call performance and customer experience

How to get started
