How to record every call on a campaign
To capture every call on a VICIdial campaign, set automatic recording and stop relying on the agent button. Here is the exact configuration.
What the server Recording Limit setting controls
The server Recording Limit caps how long a recording can run, and it also limits how long a parked call hears hold music. Here is what it touches.
Stereo recording modes: CUSTOMER_ONLY, CUSTOMER_MUTE, BOTH_CHANNELS
Stereo recording has three active modes that decide which side of the call gets captured. Here is exactly what each one records and when you would pick it.
Why VICIdial recordings stop at one hour and how to extend them
By default a single VICIdial recording caps at one hour. Here is where that limit comes from and what it takes to raise it for long calls.
How to let agents start and stop their own recordings
VICIdial can hand recording control to the agent so they capture only what matters. Here is how to enable manual recording and when it makes sense.
Why recording the customer and agent on separate channels helps QA
Splitting the agent and customer onto their own channels turns a single muddy track into two clean ones. Here is why that small change makes quality review faster and more accurate.
What Recording Delay does and why it cuts short clips
Recording Delay holds off the start of a recording for a set number of seconds so very short calls never produce a file. Here is how it works and why it saves disk and load.
Using AXFER to blind-transfer a customer into an AGI or IVR
AXFER in the number-to-dial field lets an agent push a customer straight into an AGI script or IVR with no live party on the far end. Here is how it is wired.
Reading the 3-way press-1 special extension (49907, dial prefix, phone code, number)
That long 49907... string an agent dials to start a press-1 call is not random. Here is how to read each piece so you can build and debug it.
Every value of the transfer_conference API: BLIND_TRANSFER, LOCAL_CLOSER, and more

force_fronter_audio_stop: silencing fronter audio playback after a handoff
After a fronter leaves a 3-way, audio they were playing can keep running in their session. force_fronter_audio_stop kills it from the closer side.
tw_check and md_check: blocking transfers when a 3-way is already active
Two optional safety flags on the transfer API stop an agent from stacking a new 3-way on top of one they never cleaned up. Here is what each checks.
How VICIdial call recording actually works
A full walkthrough of VICIdial call recording: the four campaign modes, where files land on disk, delay and filename controls, agent mute and start-stop, PCI DTMF muting, and stereo.
How the Mute Recording button works for agents
The Mute Recording button lets an agent pause or silence a live recording mid-call. Here is what it does, the 15-minute rule, and how it interacts with DTMF muting.

The Allow Recording DTMF Detection system setting explained
This one platform-wide flag is what lets VICIdial notice keypad tones during a recording. Without it, every per-campaign mute value does nothing.
Recording DTMF Muting explained: hiding card numbers for PCI
Recording DTMF Muting drops audio for a set number of seconds after a keypad tone is detected, so card numbers never land in your recordings.
agi-3way_press_agent.agi: the first script behind 3-way press-1 calls
When an agent fires a 3-way call to an outside agent who has to press 1, this is the first of two scripts that runs. Here is what it does and how it is wired.
