It depends on the information provided to reach them. I usually try to make contact in a verifiable format; business email, at work number, etc. if these options ar not available, then I will usually speak with people on the phone and ask that they text or email me a copy of their business card for future contact (because it is something tangible I can put with my notes, etc.).

I have even met individuals for dinner when I have been filling an executive position.
