trunks to the Emergency Services Network Entity (ESNE) to route the Emergency Services
Call (ESC).
2. The Generic Digits Parameter IS NOT ALLOWED TO BE SENT IN THE IAM WHEN
USING WRLS_CLD!
3. The Calling Party Number MUST be included in the IAM message. The Charge Number may
also be included in the IAM, but if so it MUST be the SAME as the Calling Party Number.
Although Charge Number Parameter is allowed as an optional parameter, it is ignored by the
NDET when using either of the WRLS_xxx signaling options.
