Service not available after configuring the Main trunk number on 3CX

[710]

The phone can’t register after configuring the Main trunk number on 3CX. The allocated number is always unavailable for both incoming and outgoing calls

Hi @710 could you please let me know what voip provider are you using with the FREE/SMB installation?

Also are you using any IP Phone? what model and firmware version?

Hi there, not sure which phones you are referring to, that are unable to register, as don't see any phones on your users.

Additionally, adding a main trunk number to your sip trunk is not going to affect the phones.

Can you please clarify exactly what the issue is please?

Ok, in order to configure that IP phone you must use a SBC connection either using a dedicated sbc or router phone, then you can provisioning the Yealink T58A as normal phone, this is mentioned in the guide

About the sip trunk could you please delete it and create it one more time, check that the main trunk number is set as E164 then configure the call routing to your extension and try to make a test using the web client, PWA or desktop app.

The Router Phone (Yealink T43U) is working fine, but Yealink SIP-T58A with T58A-58.86.0.39.rom firmware can not re-register after

Can you tell me the FQDN of your 3cx free system? Is it 1481.3cx.cloud?

Im afraid i dont see any SBC router phone connected. Please check the router phone is provisioned and registered first before trying to add your normal phones.

Check that the router phone has the correct firmware before provisioning it.

Here are all the guides about provisioning the phone and firmware.

I've configured everything successfully, but the Direct Inward Dialing is failing to route calls to an extension. Your assistance will be highly appreciated.
