DID Number Provisioning Guide
The number categories below describe possible requirements, not confirmed inventory. The published quote covers only the listed DID types; mobile numbers, caller ID and SMS features require separate confirmation.
Philippines DID number provisioning is strictly regulated by the NTC (National Telecommunications Commission). Understanding the different number types and provisioning processes is essential for business deployment.
Number Types and Area Codes
| Number Type | Format | Area Code Examples | Provisioning Difficulty | Typical Use |
|---|---|---|---|---|
| Landline Number | +63-2-XXXX-XXXX | Manila 02 | Moderate | Enterprise customer service, call centers |
| Landline Number | +63-32-XXX-XXXX | Cebu 032 | Moderate | Regional customer service centers |
| Landline Number | +63-82-XXX-XXXX | Davao 082 | Higher | Mindanao regional coverage |
| Mobile Number | +63-9XX-XXX-XXXX | 09xx | Higher | Mobile voice and SMS: subject to number and route confirmation |
| Toll-Free Number | +63-1800-XXX-XXXX | 1-800 | High | National customer service hotlines |
Provisioning Process and Timeline
The typical process for provisioning Philippines DID numbers through Phemio Voice:
- Submit Application Documents: Provide company registration certificate, legal representative identification, number usage declaration, and other required documents
- KYC Compliance Review: Phemio Voice assists with NTC-required compliance review, typically taking 3-5 business days
- Number Allocation: After approval, DID numbers are allocated - landline numbers in 1-3 business days, mobile numbers in 3-7 business days
- Configuration and Activation: Numbers are configured on the SIP trunk with SIP account credentials (SIP URI, authentication username/password)
- Testing and Verification: Inbound and outbound testing to confirm call quality and functionality
The entire process from document submission to activation takes approximately 5-10 business days for landline numbers and 7-15 business days for mobile numbers. Direct NTC application takes 4-8 weeks and requires a Philippine local corporate entity.
Latency from China to the Philippines
Voice route latency directly impacts call experience and call center operational efficiency. Network latency from mainland China to the Philippines depends on routing paths and transit nodes:
| Routing Path | Typical Latency | Jitter | Packet Loss | Use Case |
|---|---|---|---|---|
| China → Hong Kong POP → Manila | 45-65ms | <2ms | <0.1% | Premium call center routes |
| China → Singapore POP → Manila | 60-80ms | <3ms | <0.2% | Standard enterprise routes |
| China Direct to Manila (submarine cable) | 40-55ms | <1ms | <0.05% | Optimal, requires direct resources |
| China → Japan POP → Manila | 70-95ms | <3ms | <0.3% | Backup routing |
| China → US Transit → Manila | 150-220ms | 5-10ms | 0.5%-1% | Not recommended, poor quality |
The Philippines connects to the Asia-Pacific region through multiple international submarine cables, including SEA-US and SEA-ME-WE cable systems. The optimal route from China transits through a Hong Kong POP, leveraging the APG or SEA-US cable directly to Manila, achieving 45-65ms latency.
Routes, number eligibility, caller ID, quality, and pricing for Philippines require supplier confirmation and route tests.
BPO / Call Center Applications
The Philippines is a global BPO leader with a particularly well-developed call center sector. Here are typical voice route applications in the Philippine BPO industry:
Offshore Call Centers
Many international companies establish or outsource call centers in the Philippines to serve English-speaking markets. Philippine call center agents generally possess strong English proficiency and cultural familiarity. Through SIP trunking, headquarters can directly manage and monitor call quality and operational efficiency at Philippine call center sites.
Typical architecture: Philippine call center agents connect via local networks to the SIP trunk provider's softswitch platform, making outbound calls to target countries worldwide. Headquarters monitors and performs quality assurance via SIP extensions. Monthly traffic typically ranges from 1 million to 5 million minutes.
E-Commerce Customer Service Centers
The Philippines has a large consumer market with highly active platforms like Shopee and Lazada. International e-commerce companies entering the Philippine market need to establish local customer service teams. Using Philippine local DID numbers for customer support can significantly improve local customers' answer rates and trust. Data shows that calls from local numbers have 40%-60% higher answer rates compared to international numbers.
Financial Services Outbound
The Philippine financial services industry is growing rapidly. Banks, consumer finance companies, and P2P lending platforms need to conduct customer follow-ups, collection reminders, and other outbound campaigns. The high concurrency capacity and flexible rate structures of SIP trunking are well-suited for these batch outbound scenarios. Typical requirements: 50-200 concurrent channels, monthly traffic of 500K-2M minutes.
Online Education
The Philippines is one of the world's largest sources of English-language teachers, with many Chinese online education platforms partnering with Filipino English teachers. Voice routes are used for class scheduling reminders, teacher communications, and parent follow-ups, generating substantial China-Philippines call volume each month.

Q: What is a normal ASR for Philippines voice routes?
A: Philippines ASR varies by target network: PLDT landline ASR is typically 60%-72%, mobile ASR is 42%-58%, and smart-routed mixed traffic ASR is 45%-55%. Overall ASR below 35% is abnormal and warrants investigation of route quality, number validity, and concurrency settings. DITO network ASR fluctuates more (35%-48%) due to limited coverage.
SIP Trunk Options
When deploying SIP trunk services in the Philippines, enterprises typically have three options, each with different trade-offs in cost, quality, and compliance:
Improving Philippines Voice Route ASR: A Practical Guide
Answer Seizure Ratio (ASR) is the core metric for measuring voice route quality, directly impacting call center operational costs and business efficiency. Philippines voice route ASR typically fluctuates between 35% and 65%, influenced by carrier, target network, time of day, and dialing strategy. Below is a systematic optimization framework drawn from real-world operations.
1. Key Factors Affecting Philippines ASR
| Factor | ASR Impact | Controllability | Notes |
|---|---|---|---|
| Target network type | 15%-25% | High | Landline ASR typically exceeds mobile by 15-25 percentage points |
| Carrier route quality | 10%-20% | High | Direct vs. multi-hop transit shows significant ASR differences |
| Time of day | 10%-15% | High | Off-peak hours see大幅 drops in answer rates |
| Dialing format & number规范 | 5%-10% | High | Incorrect number format causes carrier rejection |
| Concurrency & signaling | 5%-8% | Medium | Excessive concurrency triggers carrier throttling |
| Codec negotiation | 2%-5% | Medium | Codec mismatch causes call setup failure |
| PDD (Post-Dial Delay) | 3%-5% | Medium | Excessive PDD leads to user hang-ups |
| Number blacklist / DNC filtering | 5%-15% | High | Dialing invalid numbers wastes call resources |
2. Carrier Route Optimization Strategy
ASR performance varies significantly across the three major Philippine carriers. Strategic route allocation can dramatically improve overall ASR:
| Target Network | Recommended Primary Route | Backup Route | Typical ASR Range | Key Optimization |
|---|---|---|---|---|
| PLDT Landline | PLDT Direct | Globe Transit | 60%-72% | Prioritize PLDT routes — most stable landline quality |
| Globe Mobile | Globe Direct | PLDT Transit | 45%-58% | Globe on-net ASR is optimal — avoid cross-network |
| Smart Mobile | PLDT/Smart Direct | DITO Transit | 42%-55% | Use PLDT on-net — Smart is part of PLDT group |
| DITO Mobile | DITO Direct | PLDT Transit | 35%-48% | Limited DITO coverage — ASR fluctuates |
| Unknown Network | Smart Routing | Multi-route Round-Robin | 40%-52% | Use number prefix to identify carrier automatically |
Carrier Identification Tip: Philippine mobile number prefixes identify the carrier — in the 09xx series: 0917/0927/0937/0947/0967/0977/0987 are typically Globe numbers; 0918/0919/0920/0921/0928/0929/0938/0939/0946/0947/0950/0951/0961/0963/0965/0968/0994/0998 are typically Smart/TNT numbers; 0991/0992/0993/0995 are typically DITO numbers. Use this pattern in your PBX or dialer to auto-select the optimal carrier route before initiating the call.
3. Time-of-Day Optimization
The Philippines (UTC+8) shares the same time zone as China, so there is no time difference. However, user answer habits still vary throughout the day. The following table shows time-slot ASR references based on Phemio Voice operational data:
| Time Slot (Beijing) | Philippines Time | Landline ASR | Mobile ASR | Recommendation |
|---|---|---|---|---|
| 09:00-12:00 | 09:00-12:00 | 55%-65% | 42%-52% | ✅ Best outbound calling window |
| 13:00-17:00 | 13:00-17:00 | 50%-62% | 45%-55% | ✅ Good calling window, mobile ASR rising |
| 17:00-20:00 | 17:00-20:00 | 45%-55% | 48%-58% | ⚠️ Landline ASR drops, mobile ASR rises |
| 20:00-22:00 | 20:00-22:00 | 35%-45% | 40%-50% | ⚠️ Only for specific use cases (collections/callbacks) |
| 22:00-08:00 | 22:00-08:00 | 15%-25% | 12%-20% | ❌ Do not call — extremely low ASR |
Best Practice: Concentrate core outbound call volume between 09:00-17:00. Schedule landline calls in the morning; mobile calls can extend into the afternoon and early evening. Avoid calls after 22:00 — not only is ASR extremely low, but it may trigger complaints leading to your numbers being flagged as spam.
4. Dialing Standards & Number Format
Incorrect Philippine number formatting is a common cause of call setup failure. Correct dialing formats:
| Number Type | International (E.164) | Local Dialing Format | SIP URI Format |
|---|---|---|---|
| Manila Landline | +632XXXXXXXX | 02-XXXXXXXX | sip:+632XXXXXXXX@carrier.com |
| Cebu Landline | +6332XXXXXXX | 032-XXXXXXX | sip:+6332XXXXXXX@carrier.com |
| Davao Landline | +6382XXXXXXX | 082-XXXXXXX | sip:+6382XXXXXXX@carrier.com |
| Mobile | +639XXXXXXXXX | 09XX-XXX-XXXX | sip:+639XXXXXXXXX@carrier.com |
| Toll-Free | +631800XXXXXXX | 1-800-XXX-XXXX | sip:+631800XXXXXXX@carrier.com |
Common Errors:
- Mobile numbers missing country code prefix (dialing 09171234567 instead of +639171234567)
- Landline numbers missing area code (Manila numbers without 02)
- Mixing international and local formats in SIP signaling (using both +63 and 0 prefixes)
- Incorrect number length (Philippine landlines with area code are 10 digits; mobile numbers are 11 digits)
5. Codec & Media Optimization
Codec selection directly impacts call setup success rate and voice quality:
| Codec | Bitrate | Latency | ASR Impact | Recommended Use Case |
|---|---|---|---|---|
| G.711 A-law / μ-law | 64 kbps | Very low | Best compatibility | ✅ First choice — all carriers support it |
| G.729A/B | 8 kbps | Low | Good | Bandwidth-constrained scenarios — saves 70% bandwidth |
| G.722 | 64 kbps | Very low | Good | HD voice for customer service scenarios |
| Opus | 6-510 kbps | Low | Carrier-dependent | Next-gen codec — some carriers now support it |
| iLBC | 15.2 kbps | Medium | Fair | Backup for high-packet-loss environments |
Recommended Configuration: Set codec priority in SIP INVITE to G.711 > G.729 > G.722. G.711 is the standard codec supported by all Philippine carriers, avoiding call setup failures due to codec negotiation mismatch. Use G.729 only when bandwidth is severely constrained.
6. Concurrency Control & Rate Limiting
Philippine carriers enforce rate limiting on high-concurrency calls. Exceeding thresholds causes rapid ASR degradation and potential number blocking:
| Carrier | Per-Number CPS Limit | Per-Number Concurrent Cap | Route-Level CPS Cap | Over-Limit Consequence |
|---|---|---|---|---|
| PLDT | 3-5/sec | 15-30 channels | 50-100/sec | Temporary block or 487 Busy |
| Globe | 2-4/sec | 10-25 channels | 40-80/sec | 486 Busy or 503 Service Unavailable |
| DITO | 1-3/sec | 8-15 channels | 20-50/sec | New calls rejected; established calls unaffected |
Best Practices:
- Use progressive dialing — start CPS at 60% of the limit and adjust dynamically based on real-time ASR
- Set PDD timeout to 8-12 seconds to avoid tying up channels with unresponsive numbers
- Monitor SIP 4xx/5xx response code distribution in real time — reduce dialing rate when 486 (Busy) and 487 (Canceled) ratios are high
- Rotate outbound numbers to distribute per-number load and avoid triggering carrier anti-spam mechanisms
7. Number Hygiene & DNC Compliance
Invalid numbers are among the biggest factors dragging down ASR. In the Philippine market, pay special attention to:
- Number validity verification: Run HLR (Home Location Register) lookups before calling to filter deactivated numbers — can improve ASR by 8%-15%
- DNC (Do Not Call) list filtering: The Philippine NTC maintains a national DNC registry. Calling DNC-registered numbers is a regulatory violation, and these numbers have extremely low answer rates
- Blacklist management: Maintain your own blacklist of numbers with explicit refusals, complaints, or 3+ unanswered attempts — exclude them from future campaigns
- Deduplication: Deduplicate number lists before bulk campaigns to avoid wasting channel resources on repeated calls to the same number
- Powered-off / no-signal detection: When mobile numbers are powered off or out of coverage, carriers return specific SIP response codes (e.g., 480 Temporarily Unavailable). Set a 24-48 hour cooldown for these numbers
8. Real-Time Monitoring & Smart Routing
Continuous monitoring and dynamic adjustment are key to maintaining high ASR:
| Monitoring Metric | Healthy Threshold | Alert Threshold | Optimization Action |
|---|---|---|---|
| ASR (Overall) | >50% | <35% | Switch to backup route, reduce CPS |
| ASR (Per Carrier) | >45% | <30% | Degrade that carrier route, shift traffic |
| PDD (Post-Dial Delay) | <5 sec | >8 sec | Check routing hops, switch to lower-latency route |
| ACD (Avg Call Duration) | >90 sec | <30 sec | Possible poor voice quality or false answers |
| SIP 4xx Response Ratio | <20% | >40% | Analyze 4xx cause codes, adjust dialing strategy |
| SIP 5xx Response Ratio | <3% | >8% | Upstream route failure — emergency switchover |
Recommended Smart Routing Approaches:
- Carrier-based auto-routing: Automatically identify carrier from target number prefix and select on-net direct routes
- ASR-based dynamic route switching: Auto-failover to backup routes when primary route ASR drops below threshold — no manual intervention needed
- Time-based traffic scheduling: Enable multi-route load balancing during peak hours; use cost-effective economy routes during low-traffic periods
- PDD-based early hang-up optimization: Auto-cancel calls with PDD exceeding 10 seconds, freeing channels for the next number
