Route calls intelligently based on skills, language, customer value, time of day, or geographic location. Our advanced ACD (Automatic Call Distribution) strategies ensure every caller reaches the right agent the first time.
The logic that connects callers to the right agent
Call center routes (or ACD strategies) determine how incoming calls are distributed among available agents. A well-designed routing strategy can dramatically improve first-call resolution, reduce handle time, and increase customer satisfaction.
At net-iva.com, we design custom routing logic based on your business rules. Whether you need to prioritize VIP customers, route based on language skills, or send calls to specific geographic locations, we implement it in Asterisk or FreeSWITCH.
Choose the right strategy for your contact center
| Strategy | How It Works | Best For | Complexity |
|---|---|---|---|
| Round Robin | Calls distributed evenly in circular order to each agent | Teams with equal skills, fair load distribution | Low |
| Least Idle / Most Idle | Sends call to agent who has been idle the longest (or shortest) | Balancing workload, reducing agent boredom | Low |
| Fewest Calls | Routes to agent who has handled the fewest calls (today/this shift) | Evening out call volume across team | Medium |
| Skills-Based Routing | Matches caller needs with agent skills (language, product expertise) | Technical support, multi-language call centers | High |
| Priority / VIP Routing | Identifies high-value callers and routes to premium agents | Banking, premium customer service | High |
| Geographic Routing | Routes based on caller location (area code, country) | Regional support, local language requirements | Medium |
| Time-Based Routing | Different routing based on time of day, day of week, holiday | After-hours coverage, shift changes | Medium |
| Percentage Routing | X% to Team A, Y% to Team B (A/B testing, overflow) | Testing new teams, load balancing between sites | Low |
| Tiered / Multi-Level | Level 1 support first, then escalate to Level 2 if needed | IT help desks, technical support | High |
| Simultaneous (Ring All) | All available agents ring at once, first to answer gets call | Small teams, urgent calls | Low |
Beyond basic ACD - intelligent routing for modern contact centers
Route calls based on customer data from your CRM. VIP customers go to premium agents, high-risk accounts to specialized teams, or return callers to previous agent.
Recognize returning callers and route to the same agent (agent affinity). Builds relationship and reduces repeat explanations.
Detect caller's language via IVR choice or ANI (country code) and route to agents who speak that language. Perfect for international support.
When queues get too long, automatically route to backup teams, external partners, or offer callback. Prevents abandonment.
Machine learning-based routing that predicts which agent is most likely to resolve the call quickly based on historical data.
Universal queue for voice, email, chat, and social media. Route all interactions through the same intelligent logic.
How we build your routing logic
Asterisk Queues (app_queue):
• ringall: Ring all available agents simultaneously
• leastrecent: Ring agent with longest idle time
• fewestcalls: Ring agent with fewest calls completed
• random: Random agent selection
• rrmemory: Round robin with memory (remembers last agent)
• linear: Ring agents in order (top-down)
Skills-based via queue penalties:
• Lower penalty = higher priority
• Agents can have different penalties per queue
• Dynamic penalties via realtime database
Example queue configuration:
[services]
musicclass=default
strategy=rrmemory
timeout=20
retry=5
member => SIP/agent1,0 ; penalty 0 (priority)
member => SIP/agent2,5 ; penalty 5 (lower priority)
FreeSWITCH mod_callcenter: • Tiers: Multiple agent levels with different priorities • Strategies: round-robin, longest-idle, fewest-calls, random • Real-time agent state via ESL events • Dynamic queue membership Example configuration:
How we've implemented custom routes for clients
Customer database integrated with routing engine. Premium banking clients (over €100k) automatically routed to specialized VIP team. Average speed of answer reduced from 45s to 12s for VIPs.
IVR asks caller to choose language (English, Greek, German). Calls routed to language-specific agent pools. Overflow routing to bilingual agents when primary pool is busy.
Caller ID matched to patient records. Urgent cases (recent surgery, critical results) routed to charge nurse immediately. Routine calls to appointment desk.
Level 1 agents handle basic troubleshooting. If caller asks for supervisor or issue not resolved, call escalates to Level 2 with full conversation history.
