I have an account in JustVoIP (www.justvoip.com) and I am trying to set up in my Obi200. This SIP is not the preferrable one in Obi page so I added as generic SIP and it didn't work. I also tried to set up with the expert page and added the registrar server, but I get the error "Register Failed: No Response From Server". Does anyone got this problem with JustVoIP?
