Expanding Your Cloud UC Services in Emerging Markets: Why Local Numbers Matter

Introduction: The Growing Demand for Local Numbers in Emerging Markets

Cloud-based Unified Communications (UC) is expanding rapidly across Vietnam, Laos, and Myanmar, driven by increasing business digitization and mobile-first economies. However, global UC providers and telco carriers face a key challenge: establishing a local presence in these markets.

The solution? Local DID numbers. Offering Vietnamese, Laotian, and Burmese phone numbers enables UC providers to expand seamlessly, enhance customer trust, and comply with local telecom regulations.

In this article, we explore:
✅ Why local numbers matter for UC expansion
✅ The regulatory landscape for DID numbers
✅ How SIP trunking enhances service quality
✅ How GDMS simplifies local number provisioning

Why Local Numbers Matter for Cloud UC Providers

1. Build Trust and Improve Call Answer Rates

Customers are far more likely to answer calls from a local number than from an international or toll-free number. This is particularly important in Vietnam, Laos, and Myanmar, where consumers and businesses prioritize familiarity.

🔹 Increased answer rates = Higher conversion rates
🔹 Reduces call blocking & spam filtering risks
🔹 Enhances customer engagement for contact centers & enterprises

2. Ensure Compliance with Local Telecom Regulations

Regulatory requirements in Southeast Asia often mandate that VoIP providers and UC platforms use in-country telecom infrastructure for local numbers. Many governments have strict rules regarding:

✔️ DID number allocation and licensing
✔️ Call routing through local VoIP gateways
✔️ Restrictions on international VoIP call termination

Without a local telecom partner, global UC providers risk regulatory fines, service disruptions, or outright bans.

3. Enable Cost-Effective SIP Trunking for Local and International Calls

Local SIP trunks significantly reduce call costs for businesses making frequent domestic calls. Instead of routing calls internationally, UC providers can leverage local SIP trunks to:

🔹 Lower per-minute call charges
🔹 Enhance call quality with local routing
🔹 Scale voice services efficiently with virtual numbers

This is particularly beneficial for enterprises, contact centers, and BPOs operating across multiple countries in Asia.

4. Seamless PSTN Connectivity for Enterprises

Many enterprises in Vietnam, Laos, and Myanmar still rely on traditional PSTN (Public Switched Telephone Network) infrastructure. Without local DIDs, cloud UC providers may struggle to:

✔️ Offer seamless inbound and outbound calling
✔️ Provide a hybrid cloud-PSTN phone system
✔️ Enable number portability for enterprise customers

Local DID numbers + SIP trunking bridge this gap, allowing UC providers to offer hybrid VoIP solutions that meet enterprise needs.
