403 Forbidden - Using VoIP.ms - says the username is wrong

[wwdotcomputers]

I keep getting "Call or Registration to VoIP.ms has failed. sip:[email protected]:5060 replied: 403 Forbidden; from IP:208.100.60.67:5060" when I am trying to register the 3CX instance for the first time to VoIP.ms.
I talked with their support, and they said that the username of 18700 is not my username (as show above in the error)
I did choose the correct provider on the trunk add. I did enter my correct username in the Authentication ID (SIP User ID) field.
I cannot find where to change the 18700 username to my correct one.
Please help.
Thank you.

Hi ! your username is your account number in VOIP.ms
When you are on the main page it's here


Then you will go in your 3cx instance, click on ADMIN at the left bottom, then Voice & Chat, click on your trunk and you will check the Authentication ID (SIP)

I do see that. However, it was still showing, 18700 for the sip username. I am not sure how, but the authentication now works. Thank you for helping.

Sometimes if you have issue using your main username (ex. 18700) create a sub-account (there's a subaccount tab in your voip.ms admin portal), configure it properly and then assing your DID (phone numbers) to this subaccount. It will looks like 18700_yoursubaccountname

Let me know if you need more assistance I can help you if you want

Thank you. I am good for now. I have gotten 3CX to register and authenticate, somehow, but it is doing it. I am not going to rock the boat.
Thank you again!
