Lots of users experiance one way sound problems.
My solution for this problem:
Some routers support VOIP themself. An applictation in the router uses port 5060 for that. For example a Speedtouch modem. By disabeling this application or changing the port the problems meight be solved. Your router manual will tell your how to do this. Most of the times it is done via telnet.
