I have the SPA 8800 connect to my UC320 the FXO ports work fine, but I can't get dial tone on the FXS port. The FXS port on the UC320 works fine and the FXS ports in the UC320 configuration are enabled, but I can't find any additional setting that give me a hint on what I'm doing wrong.
Any help would very much be appreciated. Thanks
In order to get dial tone, you must assign the SPA8800 FXS to a user. You can assign them by location -i.e. Lunch Room.
Let us know if this solved issue for you.
