asterisk users - Jan 2008 - Echo in the outside call (E1)

I have a little problem with mi outside calls.   I Have Echo. It`s randomly.

 

I install  codec G729 and I have Grandstream GXP2020.

 

Asterisk 1.4.9,Unicall 0.0.5pre1,Zaptel 1.4.5

 

I have a E1 and 30 channel.

 

Can you give a tip, where can I check????  If I miss something.

 

Thanks
