Redirecting Number
The Redirecting Number IE shown in Figure 4-13 identifies the called party 
number from which call redirection/diversion/transfer occurred.
NOTE:
The ASAI specification permits the Redirecting Number IE to be repeated 
within a message. The ECS uses only a single occurrence of this IE across 
the ASAI interface and does not repeat it.
.
The contents of this field are coded as shown in Called Party Number.

The ECS does not expect an ASAI adjunct to send the optional bytes 3a and 3b; 
these are shown for compatibility with the ASAI specification. If bytes 3a/3b are 
received, they are ignored.
The adjunct should be prepared to parse this IE both with and without optional 
bytes 3a and 3b.

User to User Information
The User to User Information IE shown in Figure 4-16 conveys information 
between ASAI applications. The ECS carries user to user information 
transparently; it does not interpret or act on user to user information. This IE can 
have a maximum of 32 bytes of user information.
The user to user information element is coded as shown below:
