Ok, I modified the supported codec on the SIP client and the call went through successfully. However, I got one way audio. UA2(callee) with public IP can hear, but UA1(caller) with private IP cannot.
The INVITE msg arrived on UA2 is like with the private IP in SDP. I think this causes the problem because UA2 (public IP) won't know how to get to private ip.
