They asked my salary range, what should I say? - what worked for you?

A recruiter asked for my salary expectations on a first call as I look for work as a call-centre agent. Thank you in advance. I also do not want to sell myself short. What did you say?

Keep everything in writing and save the confirmation numbers. It saved me later.

I gave a range based on local postings and said I was flexible depending on the whole package. They did not push back.
