19:52:54 Internet is Connected
19:52:54 Stopping SIP Engine
19:52:54 Opening Internet Ports
19:53:02 Sip Port 5070 (UDP) opened OK
19:53:02 Local network IP is: 192.168.1.3
19:53:02 This computer is connected to Internet over a network using a NAT, router or Internet Connection Sharing
19:53:02 Checking with STUN
19:53:14 NAT is symmetric so STUN will not work.
19:53:14 Checking for a UPnP NAT
19:53:24 No UPnP NAT or router found
19:53:24 Because NAT or router is 'symmetric' networking will be slow unless you setup NAT manually

I am not able to make calls. I have checked the setting in my router mt841. All the ports are open still having problem.
