Call-Type After Multiple Digit Translations

Normally after a digit translation, the call-type is retrieved from the resulting Destination. It is possible
that further digit translations will occur, for example, the re-translation on the LRN after an LNP query.
Normally the call-type from the original translation is used after subsequent translations. So, the
call-type in the Destination resulting from the LRN translation is ignored, in favor of the original
call-type resulting from the original called DN translation. An exception is that the call-type can change
from a translation for policy-nxx. For example, dialed digits 611 translate to a Destination with call-type
REPAIR, which has a route-guide containing policy-type=NXX, with a policy-nxx containing a new
"translated-dn". In this case, a new translation on the translated-dn occurs, and the new Destination
call-type is used subsequently during the call. This is necessary to prevent problems related to a possible
> NXX (800 toll-free) translation.
