I made 45 consecutive structured calls in my life, many times actually. I always could interpret the result in many ways, most of the time complete opposites were the leading interpretations. Their actual behavior afterwards told me the reality. People on the phone will say a lot of things, and it's very easy to accidentally make them reply what you want to hear even though they don't mean it.
Interviewing 45 people can provide much more meaningful information than sending a survey to 1000 people. I'm not saying it's the case there, I'm not an expert in this domain. But 45 semi structured phones interviews is perfectly fine for a lot of research.
