Hello Community,
I am experiencing an issue with outbound calls on my 3CX SMB Free system. Inbound calls are working perfectly fine, but when I try to dial an external number, I receive the error message "3cx cannot complete this call the number may be incorrect or Unavalible".
Here are the relevant details:
  • System Type: 3CX SMB Free (Cloud Hosted by 3CX)
  • 3CX Version: Version 20 Update 7
  • Country/Region: United Kingdom
  • Outbound Rules: I am using the standard, automatically generated outbound rules provided upon the initial VoIP setup. I have verified they appear correct for my region and provider.
I have tested calling my personal mobile number, which I know is fully functional and reachable.
I tested the SIP trunk on zoiper and outbound worked fine. Any guidance on where to check the configuration, particularly regarding outbound parameters or SIP trunk settings specific to the SMB version, would be greatly appreciated.
Thank you in advance for the help!

Hello @KMCOMPUTING

Which SIP Trunk provider are you using? Do you see an error in your event log? Also can you remove the outbound caller ID from the outbound rule and try again?
 
I am using LoveVoIP, I have a friend who uses SMB FREE and LoveVoIP and his inbound/outbound works fine. He helped me set it up.

After removing the caller id, I still get the error.
 
Can you please confirm which trunk provider you chose from the list in the Add Trunk dialogue:

On SMB Free you can ONLY use one of the supported SIP Trunk providers, set up per the guide linked for each one.

If you require another SIP provider, you will need a commercial edition. We have recently released a Basic edition if you are budget conscious. https://www.3cx.com/phone-system/basic-edition/

Ok that's fine. I'll just continue to use it as it is. Is there an explanation on how my friend can do outbound calls if he is on the same setup as me?

Thanks for your help anyway.
 
Without actually knowing your friends account details, we would be guessing. My guess is that they do not actually have the same setup.

Im not too sure. He set it up and claims its the same. I know for a fact he uses SMB. Anyways thanks for your help.
 
Check with your SIP provider they're allowing you to dial out as some new set ups require you ask for it to be enabled.

I can dial out when using the SIP settings on ZOIPER. No issues with that.
