Hi!
  As well as E and F, which are legitimate SS7 dialling characters  - SS7
uses full hexadecimal dialling, and especially E digit is extensively used
on SS7 trunks for network routing numbers (NRN), operator routing numbers (ORN)
and other intra-network or inter-network cases, at least here in Europe.
