- A-number rewrite: CallerID modification with prefix, suffix and trimming
- B-number rewrite: Called number modification
- Dial plan assignment: Linking with dial plans for internal number validation
Assigned SIP/DAHDI channels
Routing rules are assigned to specific trunks for processing incoming calls.
Applications (43 total)
Inbound routing supports 43 applications that can be chained into sequences for call processing.
Call control
Authorization
PIN code verification — the call is terminated if an incorrect PIN is entered.
Wait
Pauses processing for a specified time with optional music on hold.
Wait for dialing
Waits for DTMF input; continues to the entered number or triggers “i” (invalid).
Inter-digit timeout
Sets the timeout between individual DTMF inputs (e.g. 5 seconds between digits).
Response timeout
Maximum wait time for DTMF input from the user.
Answer call
Answers an incoming call with optional delay.
Hangup
Terminates the call with an optional cause code.
Progress
Sends a SIP 183 Session Progress message.
Maximum call duration
Enforces a call time limit with immediate termination.
Call routing
Goto (unconditional jump)
Unconditional jump to a specified extension/routing with optional time conditions.
Conditional jump
Jump based on variable comparison (=, >=, >, <=, <, !=).
Call status check
Routing based on the result of a previous call: BUSY, ANSWER, CANCEL, NOANSWER, CONGESTION, CHANUNAVAIL.
Dial channel
Routes directly to a SIP trunk with multiple playback switches.
Dial extension
Calls a single extension with configurable timeout.
Dial extensions
Simultaneous calling of multiple extensions with optional music on hold.
Dial multi-extension
Routes to a multi-extension group.
Dial outbound routing
Redirects to the outbound routing context.
Switch
Conditional routing based on switch state (on/off).
Queues and conferences
Queue
Routes to a call center queue with extensive configuration options (timeouts, fallbacks, agent announcements).
ConfBridge conference
Multi-party conference with configurable profiles.
Conference (legacy)
Legacy conference room (being replaced by ConfBridge).
Voicemail and recording
Voicemail
Routes to voicemail.
Call recording
Records the call with a customizable filename prefix.
Audio playback
Play file
Plays an audio file with optional DTMF/fax detection.
Generate tones
Generates specific tones (ringing, dial tone, busy, congestion, etc.).
Generate ringing tone
Plays a ringing tone for a specified duration.
Read number from variable
Text-to-speech number reading (with language selection).
Read digits from variable
Text-to-speech reading of individual digits.
Data management
Read DTMF into variable
Captures DTMF input into a variable with retry logic and timeout.
Read value from DB
Reads a value from the database into a variable.
Store value to DB
Writes a value to the persistent database.
Delete value from DB
Removes a value from the database.
Set variable
Assigns a value to a session variable.
Call information
Set CallerID
Modifies CallerID number and name.
Add SIP header
Inserts a custom SIP header into the signaling.
Set ring type
Configures the Alert-Info header (Bellcore-dr1 through dr5 or custom).
DISA and callback
DISA (Direct Inward System Access)
Allows remote employees to make calls through the PBX at reduced rates with PIN authentication and source number masking.
Callback
Routes a return call to an external number after the caller hangs up, with optional PIN protection.
Integration and scripting
HTTP API
Sends call information to a web server via HTTP/HTTPS with optional response processing.
Asterisk command
Executes any Asterisk application.
Script
Executes a dialplan script with variable passing.
Notifications
Send email
Sends an email with variable interpolation: CALLERID, EXTEN, DATETIME and more.
Utilities
