U5 Beta - Telnyx SMS Outbound Not Working

[Evolute IT]

Hey,

Updated to the beta from Alpha 2. Our SMS with Telnyx don't seem to work anymore. We setup SMS in the tab using the webhook and all but it seems to be inneffective.

We get this error when trying to send a message (and yes, the DID is configured correctly) : "Failed to send message(s) to the provider 'telnyx' from '[DID]' to '[NUMBER]'. Exception: Cannot find provider for number [DID]"

Hello

That message will appear if you have SMS chats open and then the DID that was used by the sending extension to start those SMS chats was deleted and you try to sent further messages in those sms conversations.

Can you check the following for me please?

- Go to your sip trunks and check in your Trunk settings that your DID is still listed in trunk settings >> DIDs
- Also go to Inbound rules if you can see the DID is listed
- Edit your extension that you are using to send those messages, scroll down to the "enable SMS section make sure your DID is selected in the "Can send SMS via" field.

can you try the steps above and let us know?

I checked everything you said. DID is all perfectly set (works for calls.)

I had 1 chat still opened using the old config but not with that number (it was an inbound 2FA code.) Even after "dealt with" that one, it doesn't send still.

Someone else reporting issues with Twilio as well

I wonder if something changed in U5 or something going on with messaging proxy (likely in relations to prep to remove it and have SMS go direct). I tested on a U3 system with Flowroute and messages go through no issue.

Actually, in U5, when using the SIP Trunk SMS tab, the webhook is direct on the PBX itself. The messaging proxy is being discontinued.

Ah, I haven't spun up u5 yet, so didn't know it was direct.

I'll assume all applicable webhooks have been updated with new URLs?

Just to be on the same page, in v18 U5, the SMS must be configured under Sip Trunks and enable the SMS under Sip Trunk configuration SMS tab - https://www.3cx.com/docs/manual/sip-trunks/ . If previously the SMS/MMS feature was configured on U4 and you have updated the 3CX System to U5, the configuration will be located under Messaging > Facebook & SMS . You will have to remove this setup and move it under Sip Trunk.

Is this the case ?

I am aware of this. We removed the old config and the new one works for inbound but not outbound.

Did you ever get this resolved? I'm experiencing the same issue with Telnyx and 3CX 18.0 (Build 384)

I can receive text messages but cannot send them.

The case @ConceptsWeb had was resolved (his help is much appreciated).
