Dare I ask... What did the PAP's user screen say when you tried to connect? Could the ATA need a reset/reprovision? Could you need a different ATA? It's always possible that there was some kind of programming hiccup that occurred during/after the port (speaking as an outsider without direct knowledge of Voipo's provisioning practices). The softphone connection is (a) to a different server, with (b) different SIP credentials. Perhaps your provisioned SIP configuration is not quite right?
