Moving the Number from the X-Genesys-CTIKey into the Calling Number

In this instance, the implementation called for setting the Calling Number on a REFER-initiated INVITE to the number contained in the X-Genesys-CTIKey. To perform this function:

  • The contents of the X-Genesys-CTIKey header are copied to generic IE, SG User Value 1, using the SMM function.
  • A translation table copies the value from SG User Value 1 to the Calling Number IE.

Configuring the SIP Message Manipulation

  1. Select a new Message Manipulation Table. Configure the Message Selection to Refer. The SMM Table will only effect REFER messages.
     
  2. Add an entry to the table. As the X-Genesys-CTIKey header is not a pre-programmed Header Name, you must manually enter the header name.

    The entry below searches for the SIP header X-Genesys-CTIKey and copies the value of the header into the token SG User Value 1.
    Use the Header Value Add/Edit button to set the token value (not shown).
     
  3. Add the new Message Manipulation to the Outbound Message Manipulation Table
     
  4. Add a translation in the appropriate Translation Table to copy the value from SG User Value 1 into the Calling Number.
     

Important Notes

The SIP Header feature cannot generate a new SIP packet. Only arriving or leaving SIP packets changed via the SIP Header function.
