Koncert vs Orum
Two parallel dialers with the same G2 average. One also sells a single-line mode; the other builds a team room around the calls.

Quick answer
Orum is a parallel dialer first: it calls several numbers at once, detects a human answer and hands the call to the rep, with a Virtual Salesfloor for calling together and analytics on when to call. Koncert covers a wider range: a single-line AI power dialer and parallel dialing on up to five lines, with cadences and local presence. Pick Orum if you run a team of at least three callers and want live coaching in the product. Pick Koncert if some reps should dial one line and others several. Neither publishes a price.

Pick Koncert if
- Part of the team works named accounts and should dial one line at a time
- You want cadences inside the dialer
- You want to set the number of lines per rep, from one to five
Where it breaks. Koncert gives you dialer options, but choice is only useful with the volume and list quality to justify it. Parallel modes still carry the usual answer-experience and reputation trade-offs.

- The whole team lives on the phone at high volume
- Managers want live listening and coaching during sessions
- You want call-timing analytics to plan the day
Where it breaks. Orum amplifies an outbound motion that already works. With a weak list, poor positioning, or no call discipline, faster dialing just produces more bad conversations. Over-rotating on parallel dialing can also dent connect quality.
Full Orum review →Our take. On public evidence these are level: 4.6 on G2 for both, 800 reviews for Orum and 396 for Koncert. The difference is in what each assumes about your team. Orum assumes a floor of callers working in sessions, with a manager listening in, and it sets a three-seat minimum. Koncert assumes a mix, and lets you put a careful rep on one line and a volume rep on several. Either one multiplies what you already have: with a weak list or a script that does not land, more lines only produce more bad conversations, faster. We have tested Koncert and only researched Orum, so weigh our view accordingly. Ask both for a quote on the same seat count and the same number of lines.
Frequently asked questions
Which dials more lines?
Koncert states up to five lines on its top plan. Orum does not put a number in the plan descriptions we reviewed, so ask during the demo.
Is there a minimum number of seats?
Orum's Launch and Ascend plans both start at three seats. Koncert does not publish a minimum.
Do they publish prices?
No. Both are quote-only.
Do I need a parallel dialer at all?
Only if waiting for a pickup is where your reps lose their day. For a modest number of calls into named accounts, a single-line power dialer is enough, and Koncert sells one.
Still torn between the two?
We run outbound stacks for B2B teams and pick tools by what they cost per result, not by the pitch.
