[asterisk-r2] Some long distance numbers get congestion

Can you confirm the number you want to dial is: 017222164393 ? Toluca,
Estado de México?

> These numbers that fail, we have tried from other Telmex (analog) lines and they do answer normally
Yeah well, that helps to know that the numbers are OK, however, since
analog lines use a different mechanism. The last signal we receive
from Telmex is signal number 4. According to Telmex MFC/R2
specification signal number 4 from the backward side is congestion,
regardless of the context where this is received. So, you should ask
them to put  you on the line with a technical person and tell this
guy/girl why in the hell are they sending signal number 4, they have
not even asked us for our calling party category request and they shut
us down.
