[wanfish]

Hello,

My line was good weeks ago ,then the both side could not hear each other suddenly .I tried many time still not working ,so I followed the post http://forum.freephoneline.ca/viewtopic.php?f=14&t=298
and the Device Configurations from the Forum.The PAP2 could not connect to the server

Registration State: Offline

or could not connect to the loggin server .

getting worse .

No idea how to make this work .
I did the port forwarding in my router but still .
I pinged the voip.freephoneline.ca in my PC,it worked .
Any help ,thx.
