We are using a SPA122 ATA in the lobby of a police station for people to pick up the phone and it automatically dials the 911 dispatcher. We are using the following dial string:
SO<:5200>
This works fine, but the ATA does not keep this string when it is rebooted or power-cycled. It keeps all of the rest of its configuration.
Is there something else I need to do to save the configuration? I could not find anything.
Thank you,
Dave
