DID Call Limit

Overview

Daily limits on Direct Inward Dialing numbers (DID) help protect the health, compliance, and stability of outbound calling. Without limits, excessive dialing on individual DIDs can cause:

• Carrier blocking due to abnormal traffic patterns

• Decreased answer rates

• Operational inefficiencies when some DIDs are overused while others remain underutilized

Benefits of implementing daily DID limits include:

• Risk mitigation by reducing service disruption from carriers

• Improved answer rate consistency

• Operational control through transparent monitoring and configurable thresholds

Daily limits ensure dialing traffic is distributed in a controlled and consistent way, protecting both infrastructure and business reputation.

Setting daily DID limits

The pre-set available options for daily DID limits are: No Limit, 75, 100, 150, and 200. No Limit means there is no maximum number of calls that can be placed per DID per day. 

To set a DID daily call limit:

1. In Readymode iQ, click Advanced > Settings. 

2. Expand the Max Calls Per DID Per Day drop down and select from No Limit, 75, 100, 150,  or 200.

3. Click Save.

All changes, including setting the feature to No Limit, take effect after the daily update at 12:30 AM Pacific (3:30 AM Eastern).

When the DID daily limit is surpassed

If all DIDs in an area code reach their daily limit, they are removed from the general pool, and proximity switches from area code to state-level matching. If all DIDs have reached their limit, the system sends calls in a circular order from all DIDs, regardless of campaign restrictions.

This behavior is critical to understand because it overrides any previously configured campaign restrictions and can result in calls to restricted or otherwise unavailable numbers.
