For busy call centers and bustling sales organizations, having a powerful dialer loaded with the right features is like having the right engine in a vehicle — it keeps everything moving at peak performance.

Think about it. Your sales representatives do everything from managing leads to contacting prospects, following up on conversations, sending out emails and much, much more. Wouldn’t it be nice if they could do that all in one place? Forget about nice. Wouldn’t that be the most efficient way of doing things? That’s where the right dialer comes into play.

Asterisk PBX has been available for some time now with two versions, one that requires a developer and another that’s already developed and ready to go. And they’re not the only dialers on the market. CRMDialer packs a real punch, with powerful tools designed to boost sales and enhance teamwork. Let’s take a look at each of the dialers, comparing the basic functions, pricing and features.

CRMDialer vs. Asterisk PBX: Price Comparison

When you’re evaluating prices of phone systems and dialers, it helps to think of cost on a per-seat basis. This is like a per-person or per-phone calculation. In general, smaller companies typically pay a larger per-seat price while larger companies pay a smaller per-seat price.

This is an area where CRMDialer really outshines other options with a free version that lets startups get off the ground and upgrade as the business grows and the need for minutes, SMS and emails increases. Asterisk PBX offers a free 30-day trial, but CRMDialer’s free version is free for life. You can also choose from three paid plans, which offer increasing allowances of minutes, website visitor tracking, email validation and other key features.

To really get a feel for how the two dialers compare, consider the two tables below, which break down each dialer’s pricing according to the number of minutes and some of the main features included.

Contract Requirements

  • Asterisk PBX offers a month-to-month plan along with several one-year or three-year contract options.
  • CRMDialer bills monthly with no long-term contracts required.


  • Asterisk PBX and Switchvox have a five-seat requirement for all plans. In addition to set plans, Asterisk PBX consumers can design their own as needed with additional features.
