Introduction

Rhino Equipment makes Zaptel-compatible cards that can be used with FreeSWITCH and OpenZAP.

Issues

• No Dialtone on FXS ports - Make sure your card has the latest firmware.

install -m 644 rcbfx.fw /lib/firmware/
(Stop Freeswitch)
rmmod rcbfx
modprobe rcbfx
dmesg

Your dmesg output should look like this:
