No voice, which direction? Both? If so it may be a Codec issue. Check the Activity logs for any error messages right after a call.

Is this a new installation, or were the trunks working in the past? Which provider are you using?

Registration at 2022-Bridge has failed. Destination is not reachable, DNS error resolving FQDN, or service is not available.

The error suggests that there is an issue with the trunk registration. Is it an IP based trunk or authentication based?
Are you using an IP to register or an FQDN?

 

[kirankumar171]

Hi it is authentication based
yes I'm using IP

 

[kirankumar171]

Calls between extensions have audio? I would start by disabling anything that may block traffic to and from the PBX.
Also you can try a free test provider to see if audio is ok with a different provider. If it works then you need to contact your provider.

Calls between extensions audio is good only the issue with SIP trunk
