hold on guys, i work for telco.. we never have a problem..
most of the time it is telco, but.. it is caused because your software and theirs do not match... lcnt should be clean, ssck should not be in freerun... then i usually answer supervision no and ndec/fdec eth on my routes... after that open a tic with your provider and TALK to the person that shows up to test... make sure your end matches his... remember, it does not help to ask for framing, the pbx provides that.. just make sure that his end is b8zs and your start type matches... after that you could be looking at a timer...
