In the traditional TDM world, the phone or the end station was easily compatible with the existing phone lines. The backward compatibility is so strong that an operational phone from the early 20th Century can be connected to the existing telephone network.
As the intelligence shifted to the end terminals in the IP world, the phones started to deploy new capabilities. However there are still interoperability issues as the phone vendors may deploy proprietary signaling protocols. In order to ease the concern of its customers, REDCOM periodically tests various phones in the industry.
