EXS API and SwitchKit API message
Description
Use this message to control outgoing call setup during real-time call processing on the specified channel. Instructions and data are passed in the form of Information Control Blocks (ICBs).
You can preprogram a list of instructions using the Outseize Instruction List Configure message and initiate them by sending the Outseize Control message with an ICB of "Use Instruction List." Note the seize instruction cannot be pre-programmed.
An instruction that is not carried out reports a negative Acknowledgment. A positive acknowledgment is reported only if an Action ICB of "Send Host Acknowledgment" is included in the message.
Outseize instructions cannot be preprogrammed for ISDN PRI or SS7 channels. You must include all outseize instructions for ISDN PRI and SS7 in the Outseize Control message.
For an SS7 channel, this message results in an IAM being sent to the network. Mandatory parameters must be included in an SS7 Parameters ICB.

ICB NOTE: For an SS7 channel in ANSI ISUP CRM/CRA, the Outseize Control message must include an SS7 Parameters ICB. This allows a CRM message type to be part of the SS7 Parameter ICB that is sent in the Outseize Control message. To send an IAM message after an Outseize Control message with CRM, a separate PPL Event Request for IAM must be made.

Notes:
1. When the system outpulses BCD-encoded digits, a Stage N Address Data ICB must accompany the digits to define the outpulsing parameters. The position of the Data ICB is not critical.
2. The host must have a DSP configured for Call Progress Analysis for a "Do Call Progress Analysis" ICB to be invoked. For more information, refer to the message DSP SIMM Configure (0xC0)
3. A seize instruction, when present, must be the first Action ICB. A seize instruction cannot be included in a preprogrammed outseize instruction list.
4. If Answer Supervision Mode is configured for "Notify" or "Notify and Propagate," the host will be informed with a Call Processing Event message of "Answer." Note that the default Answer Supervision Mode is "Propagate."
