How to use

Assign SIP credentials, set codec preferences (G.711alaw or OPUS as supported), and verify registration with the SIP server. After registration, place and receive calls through the IP network using the connected analog handset.
Usage recommendations
For reliable fax transmission, use the FXS port dedicated to fax and confirm T.38 or interworking settings with your SIP provider if available; choose G.711alaw for compatibility where OPUS is not supported. Ensure the adapter firmware is up to date and secure the device with strong admin credentials when connecting to public or business networks.
