Thanks for the additional information.
Since only outbound calls are affected, the Disconnect Type is Endpoint, and no PCAP or SIP traces are generated, it seems the call may be ending before it reaches the SIP/telephony layer.
I would also verify your Site configuration. Under the Outbound Routes section, make sure you have configured an outbound route and associated it with the trunk that should be used for outbound calls. Sometimes the route expression is created, but the outbound route is not assigned to the site/trunk, which prevents outbound calls from being routed correctly.
If everything looks correct, I would recommend enabling diagnostic logging on the trunk, reproducing the issue, and then opening a Customer Care case with the collected logs. Since no PCAP or SIP traces are being generated, these diagnostics should help identify where the call is failing.

Hi Raphael,
Only outbound calls are not working. I also checked the interaction details, and the disconnect type is showing as Endpoint. Additionally, the PCAP and SIP traces are not being captured on the interaction page.
I tried using both Google Chrome and Microsoft Edge to access the Genesys Cloud portal. I attempted to make outbound calls, but I'm still experiencing the same issue.

Hi,
Since the WebRTC phone is registered successfully and the Simulate Call completes successfully, I have a few questions that may help narrow down the root cause:
Does the issue occur with every outbound call or only with specific destinations?
Does the interaction appear in Performance > Interactions? If so, what is the disconnect reason?
Was a PCAP generated for the failed call? If no PCAP was generated, the call may not have reached the SIP/telephony layer. If a PCAP is available, what SIP response code do you see?
I noticed the WebRTC Phone Diagnostics returned a 501 error. Is this only happening in the diagnostics, or do you see the same error during the outbound call attempt?
Have you tried reproducing the issue using another supported browser or an Incognito/Private window?
These checks should help identify whether the issue is related to the WebRTC client, the browser, or the telephony layer.
