Help Saygent with a new Logo Design

Saygent

Saas that makes phone calls instead of human call center agents. The application contacts, talks and analyzes phone calls with either customers, sales leads, job applicants or market research participants.

PLEASE NOTE: WE HAVE A CONCEPT WE LIKE (SEE ATTACHED FILE). We only want to see designs that are an iteration of this concept. Here's the brief:
1. Make the unique abstract mark look more like an "a" or "A" rather than an "o".
2. The play on the letter "a" should reflect what it shows now, i.e. talking on the phone & a hint about analysis (currently shown in the form of a pie chart inside the mark).
3. The play on the "a" should be playful and modern looking. Right now it is playful and modern but feel free to iterate.
4. Font should be modern, strong.
Please submit one with white background and one with black.
Demographic: Buyers and users of technology at businesses. Usually with bachelor or masters degrees, who want to adopt and use technology to improve business processes or to open up new opportunities by using cutting edge technologies.
Slogan is "Making Phone Calls Your Live Agents Can't", but please do NOT include it as part of the logo design.
