Yes, if a call to a test loopback address works, then your end is fine.
There are also a lot of other non-loopback test sites out there which you can also use to prove your end is fine, e.g. this is a list of Polycom test numbers: http://support.polycom.com/PolycomService/support/us/support/documentation/video_test_numbers.html
The "no video or no audio" issue is normally firewall related, but again, if calling the test numbers works, then it's not your end which is at fault. Having said that, there are some applications out there which requires additional ports to be opened to work, but that shouldn't affect you if you are dealing with systems from the major vendors.
