I get default ring tone, when I assigned caller ID ring tones.
Number in the phone book is not the same as the received number.
The period of using the ring tone was expired.
When you get default ring tone, please refer to the follows:
- The Caller ID reads the phone numbers in 10 digit format only, (012-345-6789). If displayed number is different by even just one digit by for example, area code, the assigned ring tone would not ring.
- If the caller ID ringtone was invalid, the device uses default ringtone for incoming call.
