loading a webphone

Job ID: 31074814

Budget: ₹1,500 – ₹12,500 INR

i I have two servers
and an iframe
which should load a resource (a webphone) from one server
and web pages from the other server.

If I put the resources (the webphone and the web pages) on the same server, everything works fine
but if I try to split them, the webphone is not working and I'm not getting any error.

I guess it's some problem with CORS or whatever
and I don't know what to do
since i'm not getting any error in the browser, i don't know how to proceed from here.

Server is debian 10 with apache
and the web pages are in php
