thinQ Technical Information for outbound

Connections Type: DNS SRV (preferred), DNS A, Or Direct IP



The DNS A Record is available if your installation doesn’t support DNS SRV. Just like DNS SRV, the A record is automatically updated by our APIs in the event that a service node in any of our geographies is put into maintenance mode or has an issue.

ANI: To determine jurisdiction correctly, you must provide a valid US LERG based ANI. The latest Telecom Reform Act has specific language addressing invalid or missing ANI's terminating in the US and may affect your call completion rates if a valid US ANI is not sent.

Test Call Examples and Test Numbers

We suggest completing the following test cases to allow us to fully verify your signaling. Please contact us within 48 hours of placing calls so we can pull and review traces before they expire.

DTMF Test: Feel free to dial our main line at 919-890-0000 or 877-506-0747 to verify DTMF function.

Bye From Both Ends of the Call: Complete two separate calls, one with the dialing party hanging up from their end, and another with the far end user ending the calls. Check to verify both BYEs were handled correctly.

Call Termination During Ringing: Dial any number that provides ring back (example: a cell phone) and hang up before the far end connects the call. You should see a 487 request canceled. 

Long Duration Call: A call lasting 16+ minutes to verify re-invites.

Toll Free Call: Feel free to test to our toll free number 1-877-506-0747.

For International (if testing) we offer two test numbers: 442077227711 (DTMF Test) and 39055295051 (will provide ring back).
