Call Key Variable for REST-Triggered SIPREC

For REST-triggered SIPREC, the device identifies the call to record by using a "Call Key". If the call key value in the incoming REST message is the same as the call key value of the incoming INVITE message (and matched to a rule in the SIP Recording Rules table), the device records the call.

The call key value is obtained from the INVITE message using a Message Manipulation rule that uses one of the following syntax variables in the Action Subject field:

Syntax:

Param.Call.HashKey
Param.Peer-Call.HashKey

Each variable represents a specific leg of the call. For more details, refer to the device's User's Manual.

Call Key Example

Message Type	Condition	Action Subject	Action Type	Action Value	Description
invite.request	header.X-ConversationId exists	param.call.hashkey	Modify	header.X-ConversationId	Obtains the call key value from the SIP header "X-ConversationId"
