Caller ID Management

Dialer.CX provides advanced Caller ID management with six rotation strategies, usage tracking, and flag detection. Proper CID management directly impacts answer rates — local presence dialing and healthy number rotation can increase contact rates by 30% or more.

CID Numbers

Manage your inventory of caller ID numbers:

• Add numbers individually or in bulk
• Track per-number usage (daily call count)
• Flag detection — identify numbers that may be flagged as spam
• Active/inactive toggle

Note

Numbers that are flagged as spam by carriers or reporting services will see dramatically lower answer rates. The flag detection feature monitors your CID health so you can rotate flagged numbers out of service before they drag down campaign performance.

CID Groups

Organize numbers into rotation groups:

• Group related numbers (e.g., all 212 area codes)
• Assign groups to rotation policies
• Multiple groups per policy for larger pools

Rotation Strategies

Six built-in strategies for selecting which caller ID to display:

Strategy	How It Works	Best For
Round Robin	Cycles through CIDs sequentially	Even distribution
Random	Random selection per call	Simple rotation
Area Code Match	Matches CID area code to lead’s area code	Local presence dialing
State Match	Matches CID to lead’s state	Regional presence
Least Used	Uses the CID with fewest recent calls	Flag avoidance
Weighted	Proportional usage based on assigned weights	Custom distribution

Tip

Area Code Match typically delivers the highest answer rates. When leads see a local number on their caller ID, they are significantly more likely to pick up. Combine this with Least Used as a fallback strategy to protect number health.

CID Policies

Create policies that combine strategies with CID groups:

1. Select a rotation strategy
2. Assign one or more CID groups
3. Assign the policy to campaigns
4. The system automatically selects the best CID per call

Area Code Matching

For local presence dialing:

• Built-in geographic database with 321 US area codes
• Automatic matching of lead area code to CID area code
• Fallback to a default CID when no match exists
• State-level matching as an alternative

Usage Tracking & Analytics

• Per-CID daily statistics — call count, answer rate
• Flag detection — identify numbers that may have been reported
• Health monitoring — track CID performance over time
• Usage caps — limit calls per number per day to reduce flagging risk

Caution

Exceeding 100-150 calls per number per day significantly increases the risk of being flagged as spam. Set daily caps on your CID numbers and maintain a large enough pool to stay well under this threshold. The Least Used rotation strategy helps distribute volume automatically.

Best Practices

Tip

• Rotate frequently to distribute usage across numbers
• Use area code matching for higher answer rates
• Monitor flag status and retire flagged numbers
• Maintain a healthy pool — more numbers = better rotation
• Set daily caps to prevent any single number from being overused
