I typically have my Caller ID set to “Hide Number” via the “Additional Settings” menu. Every once in a while, I am unable to make outgoing calls — upon dialing, I hear a ‘busy signal.’ As discussed elsewhere on the forum, changing the Caller ID setting to “Network Default” addresses the problem and allows outgoing calls to be made.
However, I haven’t been able to locate an explanation as to why this problem only happens sometimes? After a few days, I will change my setting back to “Hide Number” and go a few months before encountering the same problem. Does any community member know specifically why this problem will pop-up seemingly out of the blue? Is it something to do with the network? wifi? Any insight would be greatly appreciated. Thanks.
