Can I ask questions at the end of my telephone interview?

Yes ask questions at the end, but it is definitely NOT the time to discuss start dates, training and salary. Sometimes interviewers are only incharge of the first round so they may not be able to answer detailed questions, but if you make it through to the next stage you will have a chance to assess the company further.
