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:
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.
Well, there is no way to change the configuration a non-persistent way.
The dial plan you mentioned above is incorrect - the second char should be ZERO not letter O and string needs to be enclosed in () - e.g. correct dial plan is: (S0<:5200>)
it just should work.
Turn on remote syslog&debug and catch it if still not work.
