I've recently been testing a new VoIP server and was using an Obi1032 IP Phone to make calls. I was a bit upset when I started to experience one-way audio problems on some calls. One-way audio on outgoing calls usually means that the person you called will hear you, but you will not hear them.
The reason? - The far end is sending audio (RTP) packets to either the wrong IP address or the wrong RTP Port.
Without going into too much detail at this stage, the first thing to try is enabling STUN. This usually solves the problem by making sure that your VoIP equipment includes the correct public IP address and audio port in it's packets.
If STUN does not work for you, find out what port range is used for RTP packets, make sure your VoIP equipment has a fixed local IP address and then forward the RTP ports in your router to the IP address of your VoIP equipment.
Happy Calling :)
