Has anyone ever installed a Grandstream GXP1625 with an OBiTALK adapter? I thought I would get a quicker answer here unless I should ask Grandstream. Though the phone has dialtone, I cannot call on it. At first I thought that getting a dialtone meant I did not have to configure it. From what I have in instructions, I do not know how to get to an online configuration page. Anyone out there ever configure these phones? Thank you.
Got it! It was just a matter of finding the URL for the phone and using specific setting for the service provider, in which case is Callcentric. Then, certain devices require rebooting.
