In the ChanSIP extension I was used to changing NAT to Yes in the advanced options of a remote extension. For a remote PJSIP extension however I do not see any NAT field in the advanced options. Is this field no longer necessary?
Correct, there is no corresponding pjsip parameter.
Fair enough. So does a pjsip extension that is going to be remote require no additional setting changes in FreePBX to account for the NAT traversal?
