Scanner, I recently had a similar issue at a customer of ours that used LCR. When they would try to dial a toll free number, they would get a recording saying that "all lines are busy" or "your call did not go thru". This was due to one of the carriers that the LCR routes calls thru was having issues or had changed their 1010 code. Essentially that is all LCR does is put the carrier's 1010 code in front of the call to force it to go thru them. If you are getting a recording telling you this, call your dial tone provider.
