Hello,

I successfully registered the VX220-G2v VoIP client to my local Asterisk server. However when I try to call or somebody calls from another VoIP terminal in my local network, I get a one way audio. It seems there is no RTP streaming from the VX220-G2v VoIP client to Asterisk, whereas there is normal SIP communication between the two and also normal RTP streaming from Asterisk to the VX220-G2v. I don't think it's a NAT problem as my server and the clients are in the same local network (192.168.1.1). Maybe a firmware bug?  Any idea? 

Thanks
