Texting through 3CX with Telnyx

[VoyantPhone]

Does anyone have experience with both of these providers and sending texts through them? Since 3CX no longer works with Telnyx, there isn't a lot of help on the corporate 3CX side. Unfortunately, Telnyx's documentation is also pretty bad.

This is where I am. I have a sip trunk set up for SMS in 3CX. I also have a messaging profile in Telnyx. I can send texts to my number and the 3CX app receives the messages. However, when I reply to the text, the app says it went , but the receiver never gets the text. I had to create a sip connection in Telnyx called SMS so there would be credentials to enter into the 3cx sip trunk setup in 3CX, but in the Telnyx SMS sip connection I did not assign the phone number, because that number is also being used for voice calls (and assigned to the voice sip connection).

I am missing something obvious, I hope. Is there a document anywhere that gives step by step instruction to be able to send and receive texts from 3CX through Telnyx?

If not, can anybody tell me what i missed? Or at least ask me the right questions so i can explain better what's going on so they can help me get this figured out?

As far as I remember you need a messaging profile to get the API keys etc and a number. From the number settings you can assign it to the messaging profile. You can assign it to both a messaging profile and a voice SIP connection.
You will also need to complete the compliance 10DLC documents to be able to send messages.

You could also switch to a supported provider where we can better help you if you run into any issues.

I had a similar issue, and it had something to do with the SMS portion of a number. Each number can have a voice portion that can be ported and a SMS portion that can be ported at the same time or separately. In my case the voice portion was with Telnyx and the SMS was with a different provider. Telnyx support needed to update the SMS portion on their side so that it was no longer connected to them. I assume you want the SMS portion with Telnyx but it could be still with the previous carrier. Telnyx support should be able to tell you that. They can port just the SMS portion. I hope this helps

I am haivng the same issue. Telnyx used to work with the system till the lates update now I can only recieve. I orginalal switched to Telnyx fro everything becaus they were supported and one of the first carriers to work with texting. The perffered carriers list keeps shrinking and that is a shame. The current perfered carriers are so much more expensive.

Have you contacted Telnyx about this? Perhaps they made a change on their end?

I fouind the answer in my debug logs. The other carriers are rejecting it because of my campain status. I am trying to get it reverified right now. It just so happened it corrosponded with my upgrade to the latest version.

Problem solved. Turns out there were 2 issues. The first was that the API key I was using for the messaging app was incomplete. I created a new Key and the texts made it out of 3cx to Telnyx, but they were still blocked.

The second Issue was 10DLC. I had to set up an entire Brand, Campaign, etc. Took an hour or so to apply, but then took another 5 days to get Telnyx and then 3rd party approval. A royal pain in the butt.

In the end, however, texts are now being both sent and received at that extension/phone number. Thanks to Telnyx support for their help. 3CX refused to help me because I wasn't working with an "approved" vendor.

Ever since updating to V20, I have Telnyx and cant get any SMS working, inbound or outbound, any way to get this fixed? Im trying to get telnyx support to fix the issue, but not sure what they can do..

You have to register a campaing with Telnyx. It jsut so happened this started when 3cx pushed an upgrade.

We have a Telnyx SMS campaign already setup before we upgraded from V18 to V20, the 10DLC campaign and brand are active and verified as well, so its not that.

I can confirm that Telnyx continues work after upgrade to V20 and to current U7 RC, if you have a valid campaign and it's assigned to the number your using, i suggest you work with Telnyx they will work the traces with you.

I had it configured and working until 2 days ago. Now we get an error back from Telnyx that says "Invalid 'to' field". Sad days. I've reached out to Telnyx to see if they changed something.
