Re: 403 forbidden

[Pradeep Patidar]

Hello,

To assist with the investigation, please perform a Call Simulation under Tools -> Call Simulation. Additionally, please retrieve the Egress trace for the call by right-clicking on the corresponding CDR.

Could you please provide screenshots of both the simulation results and the Egress trace for our review?

Thanks and Regards

Hello team,
I'm new to DNL. I installed the Community version 6 before upgrading to the commercial version to familiarize myself with the system. I followed the available documentation, but I've reached the point where calls aren't going through.
Could you help me with this problem?

So, let me explain what's happening on my end. When I run the simulation, the result is correct; it adds the tech prefix requested by the operator. But when I make a real call, the call doesn't even go through to the operator, giving me a 403 Forbidden error.

hello Pradeep,

[Pradeep Patidar]

Hello,

Upon review, I noted a discrepancy between the hostname and the source IP being used at the ingress level. The hostname main.pbx1.supertech.it.com resolves to 91.98.195.80, whereas the CDRs indicate traffic is originating from 172.110.233.41.

I have updated the ingress configuration to include both IP addresses to ensure consistent call processing. Please attempt a few test calls and let us know if the issue persists

Thanks and Regards

Hello 

Go to Routing >>Trunk  >>Inbound >> edit

and check "Tech Prefix" value in client is same as you used in DINS

you must use prefix that you already added under ingress tech prefix
