[Asterisk-Users] Strange softphone problem

[Cinoss]

Now here is strange problem i experience. Setup is easy, IAX line out
with SIP softphone registered to Asterisk. All work fine except for one
client. When using Sjphone the other end can not hear a thing. When
using X-pro the opposite happens, local user can not hear a thing. These
softphones work fine on other clients on same network. I've also tested
several headsets but same outcome. Also same SIP account works on other
clients fine. Client is WinXP SP2 with no firewall activated.
