how to solve PHONE_NUMBER_NOT_SUPPORTED_FOR_COUNTRY error

[NAM GIANG LE]

Im trying using adwords api to add  CallFeedItem via CampaignExtensionSettingService, but it failed with a PHONE_NUMBER_NOT_SUPPORTED_FOR_COUNTRY error.

With same phone number, there's no problem when i use Dashboard or Adwords Editor.

I tried to find documentation about this rule but not found anything.

Can you help me to explain what i did wrong and how to fix it? 

Thank you.

here is my SOAP request and response. (i hide phone number)

Hi Nam,

Just wondering if the phone number is of the right format? I couldn't get it to work with the Google Ads UI either. If you have this working in the UI, could you point me to a campaign ID by responding privately to this email?

Cheers
Anash
