Hey Abdirahman!
We don't have a feature that works like that unfortunately. If we integrate with the application, you will be given an option to input your SIP + Account details.
In this case, we don't natively integrate with Zadarma, so the only option to create a connection between the two would be to use a webhook - However, I'm not sure how ideal that solution is for calling!
Please let me know if that helps ๐
