SIP trunk for Zadarma in France

[PFLUGFELDER]

Hello,
My setup has been working fine for a few weeks now, and I've already asked Zadarma's customer support but it appears it's a 3CX issue, since Zadarma is not supported in france, I need help, it is now saying forced unregister upon SIP trunk checking and I don't know what to do.
Thanks,

Hi,

I'm based in Portugal and I've been using a SIP trunk from Zadarma. My setup was working fine for a few weeks, but recently the trunk started failing with a “forced unregister” message during the SIP trunk check.

What’s strange is that Zadarma only appears under Telxi in the 3CX Free version, and there is no option to create a generic SIP trunk. To test this, I installed 3CX Pro on my PC and, in that version, the generic SIP trunk option is available and the Zadarma trunk works without any issues using the exact same credentials.

So at this point it seems that:

• Zadarma is not officially supported in Portugal or France, as listed by 3CX.
• The Free edition only allows approved providers (like Telxi), which makes Zadarma unusable.
• The Pro edition still allows a generic SIP trunk, and with that the Zadarma configuration works normally.

Is this a known limitation of the Free edition? And is there any workaround to use Zadarma without upgrading to Pro?

Thanks,
