I am using FreeSWITCH (Version 1.6.12  64bit) I am able to register sip softphone  and able to make peer to peer calls without any problem.

But I am not able to dial any mobile or fixed line number.

External gateway is showing registered. Any help will be highly appreciated. 

Following is the log i get in cli :
