Having trouble with SMS via VoIP.ms

[wwdotcomputers]

I am having trouble periodically sending SMS out. Inbound works fine, and it is a periodic problem. I have tried redoing the BEARER TOKEN. The logs show that there is an authentication error. VoIP.ms says it is on 3CX side. I used the default VoIP.ms template when I set up the SIP trunk. I think this just started happening in v20.

I've been having this same issue for a month. None of the configuration guides seem to address the issue. Appears to occur more frequently with other users.

Do you see an error in the Event Log of the PBX ? If so what does it say exactly?

Thank you. We will look into it with the provider to get to the bottom of this

Hi Yiannis, we're having the same issue. Messaging works fine on the SIP trunk provider (voip.ms) however, 3CX errors out as follows. Can you please provide a solution?

Hello,
We are having the same issue as well. It stated for us around October 5th. We get the same error on about every 3 out of 4 texts. Not exactly that but around that. Some succeed.

I just checked again and 5 out of 5 succeeded. This has probably been fixed.

Hi everyone, also wanted to let you know that after about 3 weeks of having this issue, SMS messaging seems to be wroking today for the first time.

VoIP.MS has confirmed that they released a fix for the authentication issue. We tested on our end and it seems to be resolved. Please let us know if you are still having issues.
