Is this the same Alper from Turkey that gave me the fine bottle of spirits on his last trip to NJ?
If you have one way audio Tenor-to-Tenor, then I can almost guarantee that this is not a problem with the Tenor, but, as mentioned in the previous responses, either the IP address is not forwarded correctly or the ISP is blocking VoIP. A good way to test is if you have a 3rd Tenor setup, have each of the other 2 (Poland & Turkey) call to the 3rd and see which one you get voice in one direction. That will tell you which location has the problem. You should also be able to test to Quintum’s Tenor.
