Consecutive Failures

The Consec Fails (Consecutive Failures) increments a count of SIP failure responses. (The counter does not include SIP 200 responses for connected calls.) This simplistic measurement can measure a carrier's ability to connect calls: a connected call resets the counter, a failed call increments the counter by one.


This mechanism can show false positives if the customer sends missed call traffic or calls wrong numbers. The counter is a quick way to see if a route is failing but should not be used as a comprehensive success monitor.

Code Consistency

Code Consistency measures changes to response codes (specifically SIP 200 and 404s) returned from the carrier. It is useful for identifying routes of varying or poor quality. Effective carriers try to maintain 100% code consistency.

Reply Management

Customers can use the Reply Management tab to customize responses based on the SIP message received from the carrier. This allows for more efficient messaging and system responses.

To edit Reply Codes:

  1. Select Edit on the right
  2. Select the action
    • Failover- allows the call to try the next carrier
    • Replace- enter the New Code and New Reason


Carrier Authentication uses IP addresses to allow or disallow attempts to access service.

To add a new authorized IP address:

  1. Click the + button on the right.
  2. Add details in the Basic and Advanced tabs to complete the IP's entry.
  3. Then click Save.

Outbound Proxy

On the Advanced tab, setting the Outbound Proxy and related Weights will route traffic through the specific IP. This reduces management overhead as a customer only needs to authorize the single IP. Additionally, multiple addresses can be load balanced using the AnyEdge system.


The Failover tab lists calls that failed with this carrier but connected with another carrier. This typically helps to troubleshoot an issue with carrier that is failing the calls. This can also be used to identify FAS (False Answer Supervision) billing fraud.

ConnexCS will halt routing on the following codes

  • 3XX (Re-write to 503)
  • 486
  • 480
  • 404
