Wait for Call Step
Waits for and answers in-bound telephone calls.

Properties
TIMEOUT (seconds) (0 = wait forever): The length of time, in seconds, this step will wait for an inbound call. If in this time there is no call, the application will follow the path of the Time-Out 
icon. E.g.: 60 evaluates to 60 seconds, or 1 minute. If set to empty (the default) or zero the step will wait for a call indefinitely. By default, the Time-Out action step is hidden, as this feature is rarely used.
Wait for Rings: Indicates the number of rings to wait before moving to the next step. How this is handled is determined by the following two options:
- Pickup after rings: The number of rings the application will wait before picking up an incoming call. E.g.: 2 or @RINGS (application-defined variable). The default value is 2. If left empty, or set to 0, TeleFlow will pick up the call immediately. If you are connecting to an analog telephone circuit, and you wish to capture Caller Id, make sure that you set the ring count to 2 or more.
- Do not pickup after rings: After this number of rings, the application successfully leaves the Wait for Call step, but doesn't pickup or answer the phone. This can be used to decide whether or not to actually accept the call. (If, for example, the Caller Id is from a number you have decided to block calls from, you can
Hang Up instead, and deny the call. If you choose to pick up the phone, use the 
Pick Up step.)
Variable to receive Caller Id: Variable to capture the telephone number that initiated the incoming call. e.g.: @CALLERINFO (application-defined variable) May be left blank.
Variable to receive Called Id: Variable to capture the telephone number that was dialed in order to initiate the incoming call. e.g.: @CALLERDIALED (application-defined variable) May be left blank.
Connection delay (ms): Because some analog circuits take time to establish a connection with the caller after the call is picked up, a connection delay is supported that will pause the application for a specified duration, in milliseconds. The default connection delay is 500. Set this field to empty or 0 to disable the connection delay.
Protocol Specific Settings: This section contains options that apply to specific telephony protocols only. Current options available are:
Number of inbound digits: For CAS/Wink Start protocol, this determines the number of incoming DNIS/Called Id digits to wait for before leaving the step.
Action Steps
Time-Out: No incoming call was detected in the time set in the TIMEOUT field.
Supported Telephony Hardware Platforms
AudioCodes (Ai-Logix)
Dialogic

Special Hardware Considerations
Not picking up the phone and subsequently using the Pick Up step, or Hang Up step is only fully supported on digital telephone circuits, and currently only on the NMS Communications platform.
