Set the Original Call ID

For double recording (if implemented – see Set up Your SIPREC Client for Double Recording) and recording identification, the “Original Call ID” (sysCallId) recording attribute is used. This attribute is displayed in the 'Original Call I' column on the Interactions page (see Interactions).

The Original Call ID value is set in the proprietary AC-SESSION-ID or X-AUDC-CALL-ID SIP INVITE message headers and must be unique for the call. In the case of double recording, this value must be identical for both recordings.

If both headers exist in the SIPREC INVITE message, the X-AUDC-CALL-ID has higher priority.
If none of the headers exist, a random value is generated internally for the Original Call ID.

In the SIP header, the identifier must adhere to the following conventions:

■ AC-SESSION-ID – a valid hexadecimal number of exactly 16 characters

■ X-AUDC-CALL-ID – a value composed of digits, letters (uppercase or lowercase), underscore, and/or minus signs; maximum 64 characters

For the AC-Session-ID to be generated and inserted in the INVITE message:
On the AudioCodes SBC, set the following parameter in the global INI file:
SendAcSessionIDHeader = 1
