We are currently testing the integration with the Oasis PMS system. Does 3CX require open ports to connect with the PMS? If so, what is the required port range?

On Oasis's side, they report that after a few hours of connection, their backend shows 3CX as disconnected. I have to restart the hotel service to re-establish the connection. Is there a solution on the 3CX side to address this issue?
 
Its likely to be a firewall problem which closes the port after not seeing any activity. Maybe try it with an on premise install next to the PMS system or is it also a cloud solution.

If customer can get us a contact and you can contact OASIS to get an official cooperation going then we can do our own interop testing with it but likely its a firewall issue to be frank.

Hello TonyLin,
it indeed looks like a firewall issue.

Try adding HOTEL_MODULE_LINK_ALIVE parameter with a value of 300 in Advanced > Parameters.
Then restart "3CX PhoneSystem Hotel Service".
PBX will send link alive message every 5 minutes.

If the problem persists, please collect Verbose logs.
