Resolution
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.
These are the three ways to configure the Cisco ATA 186:
- Through the Interactive Voice Response (IVR)
- Through a Web Server
- Through a TFTP Server
