Ok, I realize it's probably a common issue due to nat/network configuration, but I still couldn't fix that.
Issue is, when someone calls me, everything works fine. When I call back this person, he can't hear me, I can hear him.
I use sipdicount, my only provider setup in voxalot for now. Then ipkall to get a phone number.
I tried (all?) combinations of port forwarding, dmz, playing with QoS, and the settings on my spa3000 (nat enable, keep alive...).
Any idea?
Thanks,
KiniK.
