What is CPS Control in VOS3000?

CPS means Calls Per Second. In VOS3000, Calls Per Second 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 CPS 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 (Calls Per Second Control) acts as a traffic shaping mechanism at gateway level.

CPS Control vs System Protection

CPS 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.
