High-volume call centers must optimize agent productivity to maximize ROI. Multi-line parallel dialing software can be a critical tool to meet this goal. It connects more customers to agents more efficiently, resulting in more live conversations, less idle time, manageable scalability, and improved outbound calling efficiency.
Here’s what you need to know about parallel dialing — and how you can enhance that speed-to-lead, which is a determining factor in getting new customers.
What Is Multi-Line Parallel Dialing Software?
Multi-line parallel dialing software simultaneously dials a set of numbers configured in the system. Once an active line connects to a lead, it is routed to an available agent. All other calls are dropped until an agent is available to take another call.
Parallel vs. Power Dialing
Parallel dialing and power dialing both minimize dead time between calls. Both use an automated system to dial phone numbers so agents do not have to waste time with manual keystrokes. What makes parallel dialing distinct from power dialing is the ability to try many numbers at once.
While power dialing automatically goes through a list of predetermined contacts, parallel dialing does a batch simultaneously. This increases the chances of getting a person on the line. It optimizes agent time as they move seamlessly from one live conversation to the next.
How Multi-Line Parallel Dialing Works
Parallel dialers use an algorithm to determine how many calls to place at a time. These pull from your lead list and log call information for after-call work.
The workflow for parallel dialing software works as follows:
- Upload leads or sync CRM system
- Software dials multiple numbers
- Live answer detection
- Connects to an agent
- Logs call for after-call work
Agents therefore can spend time engaging with live leads instead of waiting for an answer. The system greatly minimizes post-call log work so agents can move quickly to the next prospect. As the numbers are synced with your CRM or limited to a list you choose, there’s less worry of dead or irrelevant numbers cluttering up the workflow.
Why Sales Teams Use Parallel Dialers
Parallel dialers help your call center facilitate high-volume calls efficiently. As such, sales teams benefit from more live conversations. That increases agent productivity as their time is devoted to high-value work. The faster lead response time afforded by parallel dialers means greater contact engagement — and more opportunities to earn revenue.
Multi-Line Parallel Dialing vs. Other Dialing Modes
There are clear benefits of multi-line parallel dialing. But choosing the right dialer type depends on the nature of your contact center operations. One dialer type won’t meet all your needs, and some types might come with unnecessary features.
CallTools’ cloud-based software provides your contact center with a variety of dialer types to support your current campaign or company needs. To determine what’s right for you, do a quick comparison, keeping your current operations and future business plans in mind.
These are the key benefits for different dialer types:
Essential Features in Multi-Line Parallel Dialing Software
Just as dialer types are important, choosing parallel dialing software that supports your company’s needs ensures success. Look for these key features when selecting a software solution:
Multiple dialing modes
This allows you to customize the features of the parallel dialing system. You can choose how many lines to dial at once, call frequency and speed, and the criteria to include a number in a batch. You can also typically switch from parallel to power mode according to current operational needs.
Answering machine detection
A preferred parallel dialing system can detect when a person has picked up the call so an agent can engage with a live contact. When the software detects an answering machine or voicemail, it immediately drops the call to avoid wasted time and resources.
Caller ID management
Protecting your caller ID display requires vigilance and the right tools to show when your phone numbers receive flags. A flag on your numbers can cause them to display as “Scam Risk” or “Suspected Spam.”
Caller ID management includes ongoing auditing of your numbers, diligent lead list scrubbing (such as the DNC and RND), and ethical dialing habits. These practices improve call connection rates and build consumer trust in your outbound calls.
Built-in CRM integrations
A multi-line parallel dialing software that integrates directly with your CRM can allow agents to move quickly through a pre-approved list of contacts. You can select which of your existing clients to include in a call campaign and easily import relevant information.
Agents can see everything they need to know about each contact while live on the line, making for friction-free conversations that maximize revenue opportunities.
Contact filtering
The right software allows you to remove numbers upon request. Filtering also means you can keep a clean number list by eliminating not-in-service phone lines.
Call recording and coaching
Recording of live calls is essential for customer record-keeping and for training new team members. A multi-line parallel dialing software facilitates this recording and coaching process as an integrated part of the overall system.
Campaign reporting
A full-service software also gives you the reports you need to analyze campaign metrics. You can use this information to reflect upon campaign success and to plan for future initiatives.
