GOautodial Open Source Omni-channel Contact Center Suite

Hello,
I'm creating and csv file , it contains : fist_name,last_name,phone_number and email.
The phone_number comes with country code like 966xxxxxxxxx.

Dial plan :
exten => _xxxxxxxxxx.,1,AGI
exten => _xxxxxxxxxx.,2,Dial(SIP/${EXTEN:10}@carrier,,tTo)
exten => _xxxxxxxxxx.,3,Hangup

We can receive calls just when I add numbers in csv. without country code (966)and choose phone code from system when I load leads.
When I call , wee see the number and country code separately.
What should I change to receive it together like 966xxxxxxxxx ?

GoAutoDial 3.3.

Thank you.
