The Cisco Analog Telephone Adaptor (ATA) 186 is a handset-to-Ethernet adaptor that interfaces regular analog phones with IP-based telephony networks. The Cisco ATA 186 has two voice ports that were designed to support legacy analog touch-tone telephones. Unlike the regular Foreign Exchange Station (FXS) ports, these cannot be interfaced with a PBX as the Cisco ATA 186 cannot send out digits on these ports. Both voice ports can be used simultaneously as long as they are configured with different telephone numbers.
