PAPT

[Veritech]

I just setup a new 3CX hested on LightSail and doing a testing on a spare trunk at Voip.ms

I created an extension and set a legacy aastra phone in my phone provisioning with the mac address of my Linksys PAPT adapter.

The adapter is registered, I can call out properly.
Calls coming in do not have audio. This seems like an RTP/NAT issue.
the PAPT has NAT mapping and NAT keep alive enabled

in phone provisioning, I have enabled the PBX delivers Audio function

Any suggestions?

Thanks

You need to run a capture for more investigations, check Activity Log and even I would recommend to check Media Server Logs. If you have more difficulties to understand I would suggest to escalate this to our support team. They will definitely help you.

Do you have STUN enabled on the ATA? How many SIP devices behind the router? If more than one, were each assigned a unique local port? Does the 3CX Activity Log show the PAP2T registering with the public IP. and correct port?
