Hi. We have circa 30 numbers setup to which all work outbound, however 4 do not work inbound. When dialled you hear "Phone Number Not Found" Our Sip provider has confirmed that the numbers are terminating correctly. Can you please take a look. This is one of the numbers that does not work on the inbound direction: It is setup exactly the same as the numbers that are working... { "id": "9224736d-88a9-4871-a914-88beda7b1983", "orgId": "12b32a8d-85ff-443d-a828-a9934e754a4b", "assistantId": "d9d6b316-2d80-4926-bd4d-7aec50f1bece", "number": "+13237471011", "createdAt": "2025-11-21T07:31:29.060Z", "updatedAt": "2025-11-21T07:31:43.627Z", "name": "Tone Local 12", "credentialId": "33f42c31-3c85-445a-b9a6-bf12785b6064", "provider": "byo-phone-number", "numberE164CheckEnabled": true, "status": "active", "providerResourceId": "a228fb68-9892-47bf-831f-d808444b49d8" } CC: @AJH

Thank you for sharing the details and highlighting the urgency. At this time, I do not have any information available that would allow me to determine why the inbound numbers are not working. If you have any additional details or specific questions, please let me know and I'll do my best to assist.

Here is further information from our provider, as you can see the call termination is correct: Signaling trace below. ====================================================================== Session 3439661312-137786750@192.104.111.34, Release Cause = 0001 Record Sequence Number = /CDR/20251120-2009-3344982815-3345001809.cdr:3344988367 Termination Stack Cause = 200 , Normal BYE Start = Thu Nov 20 20:06:07 2025 Answer = Thu Nov 20 20:06:10 2025 Release = Thu Nov 20 20:06:11 2025 Duration (Seconds) = 1 Post Dial Delay (Seconds) = 2 Termination Post Dial Delay (Milliseconds) = 560 Ring Time (Seconds) = 0 Media = WithMedia --Origination-- Trunk ID = INGRESS ANI = 19492391703 DNIS = 3237471011 RN = Call ID = 8050034-0-ERSROUTE0-2335309080@64.136.173.225 Media IP:UDP = 4.55.42.194:18988 Switched IP:UDP = 192.104.111.33:26540 Codec List = G.711u_64k,G.711a_64k,G.729,RFC 2833 --Termination-- Trunk ID = Taca ANI = 9492391703, From = 192.104.111.49 DNIS = 3237471011, To = 33f42c31-3c85-445a-b9a6-bf12785b6064.sip.vapi.ai RN = Call ID = 3439661312-0-DNS0-137786750@192.104.111.34 Media IP:UDP = 44.251.170.45:58520 Switched IP:UDP = 192.104.111.33:26542 Codec List = G.711u_64k,RFC 2833 --Routing-- Routed Digits = 3237471011 Route Selection = , Final Call Indication = Final Route Selection, OLI = CNAM Dipped = No, LNP Dipped = No, External Route Server Dipped = Yes ERS Route Table = 0, Sequence = 1, Jurisdiction = 0 Matched ERS Digits = --Packet Statistics-- Orig: Pkt In = 72, Pkt Out = 74, Byte In = 12384, Byte Out = 12728, MOS = 0.0 Term: Pkt In = 74, Pkt Out = 72, Byte In = 12728, Byte Out = 12384, MOS = 0.0

Thanks for sharing the SIP details. For your trunk configuration, you’ll want to set up the gateway where inbound and outbound are defined as follows:

[{"ip": "192.104.111.49", "inboundEnabled": true, "outboundEnabled": false},
 {"ip": "192.104.111.74", "inboundEnabled": false, "outboundEnabled": true}]

This ensures inbound calls route through the correct gateway and outbound calls use the other. Once updated, please test the affected numbers again and let us know if you still encounter issues. ---
