This is a configuration issue.

You will wonder i have found solution :)

Problem was my PRI channels order. I was using DAHDI/G1 and it option will use span two first but somehow i had only 8 channels available in span to because we had 30 channels from AT&T Flex service. After change DAHDI/g1 everything works!!!!

I am so happy now!!!!!!!!
