hello i have an on premise installation v 16.0.2.910 working all good. when i tried to update to v16 update 3 or even update 4 i get 403 error on outbound calls.
 
Hi,

Who responded 403? Your trunk provider?
 
i don't know... i get this on me phone screen
 
The first thing to do is set your logs to Verbose mode from Activity Log > Settings and restart the services.

Then make a call and wait for it to fail.

You can then go to the logs, select filter to pick the last call from the list and look at the logs

If you follow the logs by the timestamps you will see the whole conversation including who replies what to who.
 
can i do anything before the update so i do not have downtime?
 
  • 3CX Version, Standard Annual 16.0.2.910
  • Server OS, Windows Server 2019
  • Is the 3CX Server Hosted and where? local
  • IP Phone Make/Model/Firmware gxp-2140
  • Provisioning Method: Local
  • Trunk Provider OTE
  • Has the Firewall Checker passed: YES
  • Are custom Phone Templates being used: NO
 
There have been some changes on update 3 and above on the trunks section so you may have to go to the options tab and manually edit the Transport Protocol to UDP (which most providers happen to use). You can also go to the General tab and disable auto discovery and type the provider's port manually.

This is just general advice - I have no indication that this is a solution for your current issue.

Run a check as per post #4 now to see why the provider rejects the call
 
ok i'll update again on the weekend and check why i get the 403 error... do you want to download the "generate support info"?? also how to check what port is the provider using??
 
The port is likely listed in you trunk configuration now, but otherwise you would ask them. It would typically be part of the info they send you when you first sign up for service.

i read somewhere i do not remeber righ now to change the values "From : User Part" so start testing all the values inside and the one that fixed my problem is [ " OriginatorCallerID" Original Caller Number will be sent ]
 
The provider responded as follows:

02/29/2020 5:57:26 PM - Call to T:Line:10001>>6946957474@[Dev:sip:[email protected]:5060] from L:8.1[Extn:14] failed, cause: Cause: 403 Forbidden/INVITE from 195.167.16.1:5060

This means they understand the request, but refuse to fulfil it. I think you need to ask the provider why the reply with a 403 now that your logs confirm it.

If this worked in a previous 3CX version, i don't think those values would have changed just by upgrading. If changing that value fixed it, it means that the provider has specific requirements that they should communicate to you so you can set up the trunk as they want it.
We cannot guarantee interoperability however with the specific provider.
