SMS over 3CX not working

[min]

Hi there,

I have been trying to get SMS function working for a client with the service provider.

I’ve provided them the Webhook URL and in return they provided the API Key and Provider URL.
However test SMSes have continuously failed. The service provider came back with the attached error message and was wondering what header information is required inbound to 3CX.

2025-06-13 12:06:44,517 WARN [gr.cytech.smsp.vas.redirect.RedirectVAS] (smsp.smsp-13) Redirect:13377624 failed to forward mo:msg.T0.id468873580.u62.p2.f61419143908.t61489079786.k.bTest 17s.o0.c0.igsmppclient.pivotel.ogsmsp.smsp.s0.enull.pr{ "value": 0, "currency": "AUD" }.mnull.rcnull.ntnull.c13357564.r0. Target:https://xxxxxx.3cx.com.au:443/sms/generic/f242c4cf546241708bc77188d90173a3?sender={0}&dest={1}&message={2}&timestamp={14}&type={8} Status: 400 Response: { "hub.verify_token": [ "The header field is required." ] }

Any help would be much appreciated. Thank you.

You need to troubleshoot this with the provider. It needs to be a supported one.
