I recently purchased a Cisco ATA-186 off of e-bay. I knew the device was used with the Verizon Voicewing VoIP phone service but thought I would be able to unlock it fairly easily. I have come to find out that is not the case. Does anyone out there know how to unlock a Cisco ATA-186 that is password protected from Verizon Voicewing service. Any help would be greatly appreciated.
