How VOS3000 Routing Actually Works (Official Behavior)
VOS3000 uses the longest prefix match rule. When a call arrives, the system first checks the Dial Plan for the most specific prefix before falling back to shorter ones. (Official Manual, Page 219: “When multiple Dial Plans exist, the longest matching pattern will be selected.”) Advanced Routing
Dial Plan Configuration – Prefix Manipulation (With Real Examples) Advanced Routing
The Dial Plan is the foundation of advanced routing. You can add, remove, or replace digits using wildcards and escape characters.
Menu Path: Navigation → Dial Plan (or inside Routing Gateway → Additional Settings)
| Original Prefix | Target Prefix | Action | Example Number | Result |
|---|---|---|---|---|
| 0 | 0 | Keep as is | 02584316146 | 02584316146 |
| 025 | (empty) | Remove prefix | 02584316146 | 84316146 |
| * | 12345678 | Replace all | 02584316146 | 12345678 |
| 0??84 | 8431 | Pattern replace | 02584316146 | 84316146 |
| 13/L9 | 13 | Limit length | 13812345678 | 13812345678 (only if 11 digits) |
Escape characters explained (Manual Page 219): /L# = shorter than # digits, /E# = exactly # digits, /G# = longer than # digits.
Prefix Routing & Number Transformation Advanced Routing
In Routing Gateway → Additional Settings → Mapping Prefix you can add prefixes to the callee number and combine with callee dial plan rules.
Example: Add “99” prefix to all international calls for billing identification (SERVER_BILLING_GATEWAY_ROUTE_PREFIX parameter).
Least Cost Routing (LCR) – Full Setup Guide
LCR automatically chooses the cheapest gateway by comparing rate per second.
Menu Path: Navigation → Operation Management → Gateway Operation → Routing Gateway
Key parameters you must set:
- First Routing Strategy: Lowest Rate per Second (or ASR)
- Second Routing Strategy: None / ASR / Lowest Rate per Second
- Calculate routing quality in real time: Enable for dynamic ASR/ACD updates
System parameters (Navigation → Softswitch Management → Additional Settings → System Parameter):
- SS_GATEWAYFEERATEROUTESORTCONFIG = Before Current Day Total Call
- SS_GATEWAYASRROUTESORTCONFIG = Before Current Day Total Call
Profit Margin Protection – How to Stop Losing Money
VOS3000 calculates profit as: Billing Rate (Rate Group) minus Clearing Rate (gateway clearing account).
Key Setting: Lowest Profit Rate Limit (in Routing Gateway)
If profit falls below this value, the gateway is locked automatically. Advanced Routing
| Call Type | Billing Rate (per min) | Clearing Rate (per min) | Profit | Action if Lowest Profit Limit = 0.003 |
|---|---|---|---|---|
| BD Mobile | $0.018 | $0.014 | $0.004 | Route allowed |
| UK Landline | $0.009 | $0.0075 | $0.0015 | Route locked |
You can also set Max Minute Rates to block expensive gateways instantly.
Time-Based Routing & Period Control (Peak / Off-Peak)
Perfect for routing cheap routes only during off-peak hours.
Menu Path: Routing Gateway → Additional Settings → Period Control
Four sub-sections:
- Period Capacity – set different line limits by time
- Period Priority – change gateway priority by time
- Period Call Restriction – allow or forbid prefixes by time
- Period Dial Plan – rewrite numbers by time of day or weekday
Rate Groups & Clearing Accounts – The Billing Foundation
Rate Groups define how you bill your customers. Clearing Accounts define what you pay your suppliers.
Menu Path for Rate Groups: Navigation → Rate Management → Rate Group Management
Inside Rate Management you set:
- Billing rate
- Billing cycle (seconds)
- Section rate (first duration + subsequent)
- Tax rate
ASR / ACD Real-Time Filters & Dynamic Switching Advanced Routing
Enable “Calculate routing quality in real time” so the system automatically switches to backup routes when ASR or ACD drops.
Monitor everything in Business Analysis → Routing Analysis.

❓ Frequently Asked Questions (FAQ)
Q1: What is the default routing method in VOS3000?
Longest prefix match + gateway sorting strategies (Manual Page 219).
Q2: How does profit control actually work?
It compares your billing rate (Rate Group) with the gateway clearing rate and locks the route if profit is below Lowest Profit Rate Limit.
Q3: Can I route calls differently during peak hours?
Yes — use Period Control (4 sub-sections) to set different priorities, limits, and dial plans by time of day.
Q4: Where do I set Lowest Profit Rate Limit?
In Routing Gateway → edit gateway → Lowest Profit Rate Limit field.
Q5: How to enable real-time ASR sorting?
Enable “Calculate routing quality in real time” and set SS_GATEWAYASRROUTESORTCONFIG in System Parameters.
