Partner ACS 3.0. The owner was playing with the programming and now here is what has happened. Every 30 minutes or so Extension 10 will ring on the Right Intercom Key and no one is there. Also, when Line 1 rings on his phone, he has to press the Speaker Button to answer it. But instead of connecting him, it dials out. No idea what it is dialing. Also he no longer hears intercom dial tone on his intercoms. Sounds like Telco dial tone. But you can't dial out on it. Any ideas. Haven't been this stumped in a long time....Also , he has a Backup and Restore card and an ASA card installed . ASA is not active when this is happening
