Thank you for your contribution. Unfortunately, I don't feel this is a appropriate for a telecommunications company. I feel it is too complicated. Simple is the solution.
Again #13 is very nice - I like it. It looks like a modern IT company / Phone company logo, which I think is appropriate. It is simple and somewhat 'organic' which is nice.
Can you please submit #13 on white background though.
Please just stick to 2 colours. - Don't like any of the colours you have shown for: #17 , #18, #19, #20. Maybe try some of the colours as shown throughout this home page: http://www.dobson.com.au/
Make like #14 - just change grey to something, and change green to something. Couple of different combinations.
