Can I change routing rules on the fly without disrupting live calls?

Yes. ASTPP Enterprise V7 lets you update routing rules in real time, and changes apply to new calls immediately without affecting active sessions.

Does ASTPP support different routing strategies for different resellers or accounts?

Yes. You can assign unique routing sets like LCR, priority‑based, or CLI routing to individual resellers or customer groups, so each account follows its own business logic.

How easy is it to test new routes before going live?

ASTPP includes tools such as rate simulators and test routing modes, so you can validate routes, costs, and call paths without making live calls.

Can I block or limit traffic to specific destinations?

Yes. With allow/deny lists and prefix‑based controls, you can restrict or permit traffic to particular regions or prefixes, helping reduce fraud and cost spikes.

Is ASTPP routing suitable for both voice and SMS traffic?

Yes. The same routing engine can be applied to both voice and SMS, enabling coordinated, cost‑efficient handling of mixed traffic across carriers and regions.

What is call routing in VoIP?

Call routing in VoIP is a process that automatically directs incoming calls to the most appropriate agent, department, or device based on rules like time, caller ID, or IVR choices. This ensures faster, smarter connections every time.

What are the four types of calls?

The four main types of calls are: inbound calls (when customers reach out), outbound calls (when your team makes the call), internal calls (between colleagues), and external-forward calls (when a call gets transferred outside your organization).

What are the four basic operational methods for call routing?

The four basic operational methods for call routing are: skills-based (matching callers to the right agent expertise), time-based (routing calls depending on the time of day or business hours), geographic (sending calls to agents in specific locations), and IVR-based (using automated menus to guide callers to the right destination).

Different Call Routing Rules of ASTPP Enterprise Version 7

Call routing remains a core strength in ASTPP Enterprise Version 7, now with smarter real-time decisions and v7’s performance boosts. Here’s the top strategies available today:

1. Least Cost Routing (LCR)

How it works: Compares live rates across all carriers and picks the cheapest route for every call, without compromising on the call quality. Furthermore, it keeps updating every few seconds based on current pricing.
Real benefits: Resellers save big on termination costs instantly. Quality filters ensure calls don’t drop even on bargain routes.
Perfect for: Resellers and VoIP service providers aiming to reduce signaling and per‑minute costs while maintaining consistent voice quality.

2. Cost-Based Routing (CBR)

How it works: Unlike basic LCR, cost-based routing weighs cost against carrier performance (ASR, ACD, PDD). Scores each gateway and picks the best value route.
Real benefits: Finds significantly more profitable routes than simple LCR and auto-adjusts when carrier quality degrades.
Perfect for: Wholesale operators who strive for increased profit plus quality balance, not just rock-bottom prices.

3. Priority-Based Routing

How it works: Creates customer tiers (like-Gold/Silver/Bronze) and assigns priority queues. Puts VIP customers first in queue for premium service.
Real benefits: High‑value clients experience near‑perfect call completion, while regular traffic uses more cost‑effective routes, helping operators significantly improve customer retention.”
Perfect for: Call centers with enterprise clients, premium resellers committed to retaining key accounts.

4. Prefix-Based Routing

How it works: Matches the leading digits of dialed numbers against a large library of prefix patterns and routes calls through different carrier groups based on configurable routing rules.
Real benefits: Handles international traffic across a broad range of countries with ease. Enables precise least‑cost routing by region and supports management of alternative or restricted routes on a country‑by‑country basis.
Perfect for: International termination providers, multi‑country resellers, and operators managing mixed or restricted routing profiles.

5. CLI Routing

How it works: Reads the caller ID and routes calls based on the origin number, sending traffic to region‑aligned carriers that specialize in that market.
Real benefits: Delivers consistently high local completion rates, prioritizes returning customers, and applies region‑specific fraud controls to protect revenue.
Perfect for: A2P messaging providers, enterprise clients, and operators in markets where caller ID and compliance are critical.

6. Non-CLI Routing

How it works: Handles anonymous or blocked caller IDs using dedicated routing rules and directs traffic to compliant carriers that accept non‑CLI origin.
Real benefits: Offers a more cost‑effective alternative to standard CLI‑based routes, supports high‑volume messaging and flexible termination scenarios, and reliably processes anonymous traffic without rejection.
Perfect for: Wholesale termination providers, high‑volume SMS gateways, and operators focused on optimizing cost and volume.

7. Lossless Routing

How it works: If the primary route fails, traffic instantly fails over to a backup route that ensures call completion, even if the alternative path is more costly. This keeps revenue‑generating calls from being dropped.
Real benefits: Maintains near‑perfect call completion during carrier disruptions and helps preserve virtually all margin on critical traffic during outages.
Perfect for: High-priority communication services, enterprise clients, and 24/7 call centers.

These strategies in ASTPP Enterprise Version 7 integrate seamlessly with real-time billing, DID management, and v7’s new automation.

How ASTPP Routing Integrates with Billing

In ASTPP Enterprise Version 7, every routing decision is connected to real‑time billing and rating in a way that feels natural and practical.

This connection means premium customers rarely face unexpected call drops, while operators always have a clear picture of what each route is costing them which means no guessing, no surprises.
