Everything was working until 18 6 update.
Out going calls seem to work.
All trunks when called give busy signal.
Trunks are VOIP.MS, which has verified issue is with 3CX PBX

Thoughts?
 
Hi @sonnyh1

Did Voip.ms happen to mention what the issue is and show some data? I just tried using our VoIP.MS test trunks and inbound calls work perfectly.
So without further data or a description of your set up I am afraid we cannot further assist.

Are you using the default template for VoIP.MS?
Can you pass the firewall checker?
Are the trunks registered in the management console?
Did you pay your VoIP.MS invoice?
Are you getting an error prompt when dialling out?
Are you getting an error in the Activity log?

Any other details you can provider that can help us troubleshoot?
 
Hi,
Everything was working and stopped.
Trunks are registered on VOIP.MS and 3CX

Here is the "sanitized" Log for an incoming call:

This is what I got from VOIP.MS

When our server should be receiving a header more similar to this:
From: "CallerID Name"< sip:[sipaccount]@[server].voip.ms;transport=UDP >;tag=b227be76
To: < sip:[Number]@[server].voip.ms;transport=UDP >
 
Are you using the default template for VoIP.MS? - YES
Can you pass the firewall checker? - YES
Are the trunks registered in the management console? - YES
Did you pay your VoIP.MS invoice? - YES

VOIP.MS is saying that 3cx is requesting authentication for incoming calls, and should not be.

Have you tried deleting and recreating the trunk? Or a new test trunk? I’m pretty sure I saw a post recently where someone recreated the trunk to resolve an issue but don’t have the post handy to reference and don’t recall the SIP provider.
 
Yes, I deleted a trunk and re created it. Same issue

This is what they are expecting
 
Can you send us a screenshot of the inbound parameters of the trunk and let us know how your DIDs are formatted?
Also do you have multiple VoIP.ms trunks of the same system?
 
Attached PDF
inbound parameters of the trunk
Typical DID Format

All trunks are VOIP.MS and setup as individule trunks.

Does it say "voip.ms" under the 00000000 in the screenshot?
How many trunks do you have on the same machine?
What is the typical DID format for you?
 
Under the 0000000000 is the DID phone number. I have tried it both ways with 10 digit phone number and voip.ms.
5 VOIP.ms trunks
1 astrix from a private system ( works fine)
1 default webmeeting brigde
1 SBC

Each trunk is a seperate DID phone number routed th the 3CX IVR
Attached is the sanitized Trunk Detail.

I don't remember is I mentioned the 3CX is on AWS, and was working until some time after the 18 6 update.
Sorry if I didn't mention this before.

Phone number will not work. Your inbound parameters should be like this for ALL VoIP.MS trunks:

1675756763386.png

Since you have multiple VoIP.MS trunks the option "Use both "Call Source Identification" rules and "Caller Number/Name -> CalledNum" field mappings (Note: Disables catch all routing capability)" must be enabled but your DIDs must also match.

Your DIDs MUST be entered in the 10 digit format (6474XXXXXX) in all trunks otherwise inbound calls will be rejected. Also the numbers MUST be unique so they only appear once. Make sure you do not have the same numbers in different trunks.
 
Thank you.
All trunks are working excpt for one. We ended up a SIP URI for one of the problem lines.
The one line that is still causing problems seems to be a VOIP.ms issue.

Again,
Thank you for all your help!
