RE: "OBi cordless phones": don't hold your breath. There is no significant market for cordless IP phones. Several companies that were making them discontinued the products. Consumers are largely moving to cell phones instead of land lines, and business users typically prefer corded phones, either with or without wired or wireless headsets. If you prefer cordless use, just stick with high quality DECT 6.0 phones with the base station plugged into an OBi 200 or other OBi ATA. Otherwise, the OBi 10x2 IP desk phones have fantastic speakerphone audio quality, and can use corded or wireless headsets.
