DialNexa call concurrency is the number of calls your workspace can run at the same time. Open Workspace Settings > Concurrency to review guaranteed capacity, reserve lines for inbound calls, limit total simultaneous calls, or purchase additional capacity.

​
When To Change Call Concurrency

Use concurrency settings when outbound activity must leave room for incoming calls, or when you need to control simultaneous call volume. A concurrency limit controls how many calls run together, not their duration or the total number of recipients in a batch.

​
Before You Begin

Confirm the active workspace and review its current settings. For a purchase, check the wallet balance, price, available quantity, and renewal terms displayed by the dashboard. Rates and available capacity can change; use the live preview before confirming payment.

​
Reserve Inbound Capacity And Set A Ceiling

  1. Open Concurrency Configuration.
  2. Set Inbound reserve to the number of lines to hold for inbound callers at all times. This cannot exceed your guaranteed concurrency.
  3. Optionally set Dynamic inbound reserve as a percentage of running outbound calls. Leave it blank to turn it off. The dashboard accepts values from 0 to 100 percent.
  4. Set Concurrency ceiling to a positive whole number, or leave it blank for Unlimited.
  5. Click Save settings and wait for the success message.

The fixed and dynamic reserves apply together, with the larger reserve taking effect. They are not added together. Outbound campaigns cannot use the reserved inbound capacity. Review any warning that a fixed reserve makes the dynamic setting ineffective at your chosen ceiling.

​
Purchase Or Release Extra Concurrency

In Add more concurrency, use the plus or minus buttons to choose your target purchased quantity. This is the total quantity you want to retain, not just the number of new slots. For an increase, the preview shows Charged today for the remaining days of the current month and the recurring monthly total. Review both before clicking Pay. The payment comes from the workspace wallet, and renewal is billed on the first of the month.

The screenshot is an example preview, not a price guarantee or a completed purchase. Your live quantity, date, rate, and available capacity determine the displayed charge.
Reducing the target quantity releases the difference immediately when you confirm Release concurrency. The dashboard states that the current month is not refunded; the reduced monthly amount applies from the next renewal. Review the impact on capacity before confirming a reduction.

​
Verify The Result

After saving settings or completing a purchase, check Your concurrency and the configuration fields again. Reload the page to confirm the saved values. For a purchase, also review the wallet transaction history before retrying an uncertain payment.
