Analog Adapter 2 FXS Cisco SPA112

The Cisco SPA112 is a SIM adapter for analog telephones with 2 FXS ports. It allows tCisco1o integrate up to two traditional analogue devices (BCA and FAX) as PBX
extensions and take advantage of all advanced features of the VOIspeed PBX.

Caution: The firmware version supported is 1.3.3 (015) which you can get from the download section of the VOIspeed website.

 

Before connecting the power supply, connect a LAN cable (which can be found in the package) to the (blue) Internet socket. You can connect the phones to the grey sockets (PHONE 1, PHONE 2) straight away or after the configuration. The device can be switched on immediately after.

You need to wait until the LED Lights will light up and remain fixed (as on the picture above)Cisco2 however the internet LED will start flashing to indicate network activity. The SPA112 has been configured with factory defaults to acquire the IP address from a DHCP server. To find it, connect an analog telephone to one of the FXS ports and enter the sequence **** (four stars) to access the IVR apparatus. You will be invites to enter the code for the desired function. Enter the code # 110 to obtain a current IP address. If there is no DHCP server on your network, you can set a static address by following the printed manual “Quick Install” enclosed in each package which contains a complete list of codes. Except that for specific requirements, it is advisable to leave the unit with a dynamic IP address.
