How to use
Connect the analog phone or fax device to the device's FXS port, then connect the adapter to power using the supplied DC/AC power adapter rated for 100–240 V at 50/60 Hz. Configure the adapter with your SIP account credentials (server address, username, and password) using the device’s web interface or provisioning method supported by your SIP provider. Select an appropriate codec (G.711 alaw or OPUS) based on desired voice quality and available network bandwidth. Verify registration with the SIP server and perform test calls and fax transmissions to confirm proper operation.
Usage recommendations
Place the adapter near the analog device and a reliable internet connection point.

Ensure firmware is kept up to date and follow your SIP provider’s provisioning guidelines to maintain security and service reliability.
