Calling on IOS and Android via Local DID Number and Native dialer in Asterisks

Create an api in asterisks softswitch to handle calling on android and IOS linphone apps The call will work via Local number that is instead of the app calling via internet VoIP. , it will initiate the call via the app and the app fetches the Local number from the astericks softswitch. So when caller hits the call button the api fetches the DID local number from asteriks softswitch then places the call to the destination this works silently and there will be no tap tap sound . And if there is no internet in the phone it will send the call via thesame Local DID number in the astercks softswitch like this Country code,, destination number,,# that is in a pinless calling manner. But this way will make a tap tap sound . There are many apps that do calling using this type of local number way eg Boss revolution. Rebtel and Raza , Please be sure that you understand the project
