Transfer to jurisdiction assessing officer (refund case)

Hi,

I have filed my return and claimed refund showing foreign and tax deducted by foreign enterprise. 

My return has been passed to AO and the reason given by CPC is the following :

" Credits for tax payments made outside India claimed in the return , which can not be verified by CPC."

I have the following clarifications : 

1. Do i need to contact the local AO or they will contact me. 

2. Will the verification be limited to the tds certificates for foreign income or it can be anything. 

Request if someome can help me out with this.
