Currently have two POTS lines (actually one is from Vonage box) and two line corded phones are getting old and flakey. Hardly seems right to go with POTS phones when SIP phones are about the same cost. Eventually want to convert over to VOIP but will probably have the existing setup for another year or so. Whatever I do needs to be simple to use for good SAF! Have an Obi110 and Beaglebone black set up with piaf. Thinking the easiest short term may be another Obi110 for the vonage line. And that gives me a path forward when I go full VOIP. This is a home/very small business setup. Most of the nerd vittles recommendations for phones were pretty old. What's a good economical but reliable SIP corded 2 line phone?
