Description

The visual call flow designer allows you to create a routing scheme without using code. All ACR applications are available as graphic elements with a set of parameters.

General view of the designer:

Webitel: Knowledge Base > Visual Callflow > 2018-12-03_09-45-35_screenshot.png

Main blocks:

Primary Workspace
String for quick application search
ACR Application Groups
ACR applications
Application Manager - application specific parameters input
Toolbar: scale, save, cancel and online scheme debugging.

Communication between applications is from the out channel (or another, depending on the application) to the in channel. Please note that in each application there can be only one input. To re-use the application, you must hold down the button Shift on the keyboard and stretch to the desired application (this line will be green).

Приложение	Описание
Answer	Switching.	An application can send one of 3 SIP replies: 200 OK -will establish a connection. Start of call billing.. 183 Session Progress - preliminary approval of codecs. Allows you to interact with the media stream call without billing. 180 Ringing - start ringback / ringback tone (beeps).

Playback	Play the file(s) in the media channel call.	One or several types of media files preloaded in the section 09 Media can be added. The selected files will be played in a top-down sequence.
Play and get digits	Play the file(s) and write the resulting DTMF to a variable.	The main difference from the previous application is the ability to save DTMF numbers into a variable. Variable - variable in which the user-entered digit is stored. Minimum digits - minimum number of digits entered by the user. Maximum digits - maximum number of digits dialed by the user. Number of tries - number of repeated plays of files if the typed value does not meet the requirements specified above. Timeout - extension timeout after playing the last file in the list. Flush DTMF - clear the buffer with the preset value.
Sleep	Pause.	Time in milliseconds.
Queue	Waiting queue.	Place a call to a specified waiting queue from 11 Automatic Call Distributor.
Queue Timer	Asynchronous queue interaction.	The application allows you to call a set of applications while the subscriber is waiting in the queue. As soon as the call is served, the application stops running. Intervals - After how many seconds from the start of the queue waiting start the application. Retries - The number of repetitions. Set current positions - Save to variable the current value of the subscriber position in the waiting queue.
Record File	Write to file.	The application allows you to record audio or video into file and send it to Email (Requires registered SMTP parameters in domain settings). Name - The name of the file to which the media stream will be saved. Terminators - The interrupt character. Type - Type of file format. Max Seconds - Maximum recording duration in seconds. Silence Hits - The maximum duration of silence for early completion of the file recording. Email - The list of addresses to send the recorded file to Email.
Record Session	Record dialogue.	The application allows you to start / end recording conversations of telephony subscribers and the ability to send to Email (Requires registered SMTP parameters in domain settings). Action - Start or stop recording a conversation. Type - Type of file format. Stereo - Record each channel in a separate direction or mix everything into one channel. Bridged - Record only calls that have a connection (bridge) A and B side. Min Seconds - The minimum recording duration in seconds. If the duration of the conversation was less than the specified value - the file is not saved. Follow Transfer - Continue recording the dialogue after transferring the call to another subscriber. Email - The list of addresses to send the recorded file to Email.
Echo	Echo test.	The ability to listen to your own media channel with a delay (in milliseconds) or without.
Conference	The conference.	The application logs into the conference or creates a new conference with the specified name. Name - The name of the conference. PIN - Access code to the conference. Flags - Additional options from the list.
Bridge	Connect.	The application allows you to connect the current channel with a new one. This can be either a webitel user or an external number via 07 Gateways or SIP URI.
Transfer	Switch to another ACR scheme.	The application provides an exit from the current scheme and transfer to a new one.
