VoIP lines, cell phones, even high quality smartphones all fall prey to the infamous ‘crackling’ disease, a condition that can range from slightly irritating to completely disabling. Follow these steps to reset your phone system service and hopefully eliminate the crackling from your phone completely.
Contact your service provider for repair or replacement options. The only resolution for internal hardware failures is to call a phone system service tech for replacement or professional repair. Check your warranties and contracts for details on costs.
If the crackling isn’t solved try a factory reset for your routers or phones. Go the menu or settings portal and find the ‘reset to defaults’ setting or ‘master reset’. You will likely need the security settings for your device to make this work.
