CPS Control in VOS3000 – Complete Gateway Rate Limit Configuration Guide
CPS Control in VOS3000 is one of the most important advanced configurations for managing high traffic, junk calls, CC traffic and vendor/client overload situations.
VOS3000 is a carrier-grade VoIP softswitch platform widely used for telecom routing, wholesale VoIP, calling card systems and enterprise SIP routing. It is known for stability, high concurrency support and flexible gateway configuration.

What is CPS Control in VOS3000?
CPS means Calls Per Second. In VOS3000, CPS Control allows administrators to limit how many calls a specific gateway can generate per second.
By default, VOS3000 supports around 1200 CPS which is suitable for large telecom operations. However, sometimes:
Vendor sends excessive burst traffic
Client generates junk traffic
CC attack creates call flood
System gets overloaded due to abnormal spikes
In these cases, CPS Control becomes critical.
Where to Find CPS Control in VOS3000?
In VOS3000 interface:
Client Gateway = Mapping Gateway
Vendor Gateway = Routing Gateway
Step to Configure:
Go to Gateway Management
Edit Mapping Gateway (Client) OR Routing Gateway (Vendor)
Open the last tab → Others
Before the end, you will see Rate Limit
Rate Limit = CPS Control in VOS3000
Once enabled and value inserted, system will enforce CPS restriction for that specific gateway.
Where to See CPS Live Statistics?
After enabling Calls Per Second Control:
Online Mapping Gateway → You will see Calls Per Second tab
Online Routing Gateway → CPS column becomes visible
This gives real-time gateway-wise CPS monitoring and better traffic analytics.
Why CPS Control is Important?
Large volume VoIP traffic often includes:
Junk Traffic
Fraud Attempts
Call Burst from Vendor
CC (Call Center) aggressive traffic
Auto dialer floods
If CPS is not limited:
Server CPU spikes
Database overload
Call drop issues
Vendor instability
Client dispute
Proper CPS tuning ensures:
Stable routing
Controlled traffic burst
Gateway-wise isolation
Better monitoring
Enterprise-grade traffic engineering
Best CPS Strategy in VOS3000
There is no universal number. It depends on:
Server hardware
Network quality
Vendor capacity
Client behavior
Average Call Duration
Recommended practice:
Start with lower CPS (20–50 for risky vendors)
Increase gradually after monitoring
Separate high-volume and low-volume vendors
Never allow unlimited CPS on new gateway
Advanced Technical Understanding
VOS3000 internally processes signaling queues. When CPS exceeds safe processing limits:
Queue latency increases
SIP response delays occur
Memory allocation spikes
System instability risk increases
Rate Limit (CPS Control) acts as a traffic shaping mechanism at gateway level.
CPS Control vs System Protection
Calls Per Second Control is not firewall. It is traffic shaping inside VOS routing engine.
For complete protection combine:
Calls Per Second Control
Proper Server Security
SSH Port Change
Strong Root Password
IP Based Firewall

Frequently Asked Questions (FAQ)
1⃣ What is default CPS in VOS3000?
Default system CPS is around 1200 but gateway-specific CPS can be configured using Rate Limit.
2⃣ Is CPS Control per gateway or global?
CPS Control is configured per gateway (Mapping or Routing).
3⃣ Does CPS affect ASR?
If configured too low, yes. If properly tuned, it improves system stability.
4⃣ Can CPS prevent CC attacks?
It helps control burst traffic but should be combined with firewall security.
5⃣ Where exactly is Rate Limit option?
Edit Gateway → Others Tab → Rate Limit (CPS Control).
6⃣ Should every vendor have CPS limit?
Yes. Even trusted vendors should have reasonable limits to avoid unexpected traffic spikes.
7⃣ Is CPS visible in monitoring?
Yes. After enabling, Calls Per Second column appears in Online Gateway view.
