This means the platform is receiving RTB ping traffic, but the requests are not converting into connected calls.
This is very common during RTB testing or when buyer demand is low.
Common reasons include:
Buyers are not bidding
Bid amounts are too low
Required parameters are missing
Buyer filters do not match the traffic
High rejection rates from buyers
TCPA or geographic restrictions
Caller profile does not meet campaign requirements
Calls are timing out before routing
You can identify this in:
Ping-to-Call Ratio
Converted-to-Call Ratio
Inbound RTB Requests
RTB Trends Over Time
Example
If you see:
10,000 RTB requests
0 connected calls
It usually means buyers are receiving pings but rejecting the traffic or not returning valid bids.
What to check
Verify all required RTB parameters are being sent
Confirm buyers are active and bidding
Review buyer filters and targeting rules
Check processing times and timeout settings
Inspect RTB request logs for errors or reject reasons
Confirm campaigns and routing plans are configured correctly
High RTB traffic without calls is usually a traffic quality, buyer response, or configuration issue rather than a platform problem.
