Unable to Parse Twilio strange number

[sarathprasath-krishnaswamy]

I have a twilio strange numbers in a hash and i need to check the incoming numbers against it.

TWILIO Strange Numbers

In that, i could parse and check for equality for the UNKNOWN,BLOCKED & RESTRICTED by using the below code,

GlobalPhone.parse(twilio_strange_num).international_format == GlobalPhone.parse(incoming_number).international_format

The above condition is not working for ANONYMOUS Number 266696687 alone.
EMPTY number im handling seperately.

Please help me out and Suggest any other better approach to do this.
