Try disabling TTY, if enabled, in your device settings menu.
In your device phone settings, look for the TTY setting. This setting can be useful for hearing-impairments. However, when enabled, volume from your device might be increased and might not reduce as much as when the setting is disabled. If enabled, disable TTY and try again.
