Ive gone thru the forum to review similiar issues and have done the following;

The internet line is connected to the WAN port of the phone adapter and other end to modem; cat5 from adapter to wireless router (Linksys e1200)

1) I've ensured SLP ATA disabled
2) for testing i disabled router firewall

Im unsure what else I can troubleshoot and just looking for some suggestions; otherwise i have sent an email through Voip support


Thanks in advance
