Cisco ATA 191 adapter
Connect an analogue phone, fax machine or paging system to your PBX with a Cisco ATA 191 adapter.
The Cisco ATA 191 is an analogue telephone adapter. It connects analogue phones, fax machines and overhead paging systems to your PBX. It has two phone ports; each port you use needs its own SIP device.
Before you start
Section titled “Before you start”- Add a SIP device to a User under Device configuration, and click Apply configuration.
- Open Devices at the top of the PBX tab and select the device. Keep its SIP credentials open: Domain, Username and Password.
The Domain shows the server address, a colon and the port.
If Transport protocol shows TLS, TLS encryption is on for your PBX. The port in the Domain is then different, and you must set the adapter to use TLS instead of TCP, with SRTP (shown as Media encryption).
