Stand when on phone: This common technique allows your voice to project and sound more confident. Insure you are in a location where you will have no distractions and no echo. Also look into a mirror if you can. Your facial expressions will reflect through your voice.A smile = sound interested, frowning = disinterested sound
Get dressed for the occasion: Dress as if you are having an in person interview (normally wearing slippers instead of shoes to be a bit more comfortable while standing)
Be Up, Enthusiastic: You are only a resume, a piece of paper, to the potential employer. They likely have many resumes. Your enthusiasm/energy must stand out, but don't sound phony.
Speak clearly and slowly: Many people get very nervous during telephone interviews and may have a tendency to mumble into the phone. Relax, speak slowly. Do not sound rushed or anxious.
Repeat/rephrase detailed questions: restate the question before you answer to be clearly understood what is being asked.
Make preparation notes (questions): But do not write a script for the interview, just speak freely from your notes.
Be prepared to give highlights: Be prepared to give a positive two minute summary of your professional career. Rehearse this using a recorder -- avoids umms and too many uncomfortable and/or long pauses.
Asks questions: You should talk and carry the conversation, not the potential employer. Avoid yes & no answers.
NEVER ASK QUESTIONS IN THESE AREAS IN A TELEPHONE INTERVIEW

There will be time at another time to get these questions answered later or at the time of an offer.
Best of LUCK!
