1. What a SIP trunk in Myanmar actually is
A SIP trunk is the IP delivery pipe between a carrier and your PBX, AI voice agent, or call-control platform; signaling over SIP, audio over RTP. A Myanmar SIP trunk is the same thing carrying +95 Myanmar DIDs allocated under PTD.
DIDHub provides the trunk authentication and SIP transport; PTD-compliant number allocation is coordinated through our in-region carrier partners. Your PBX or platform sees a standard SIP trunk; we handle the regulator-side paperwork.
2. Myanmar regulation: PTD, KYC, compliance
PTD requires KYC documentation before any Myanmar DID can be allocated. Activation typically takes 15-30 business days. DIDHub handles the document submission and regulator coordination on your behalf.
What people typically use a Myanmar SIP trunk for:
- Myanmar market presence (sanctions and operational considerations apply), Yangon for limited B2B presence.
- Tourism inbound, Bagan, Inle Lake (subject to current travel realities).
- Toll-free, free for Myanmar callers.
Myanmar's regulator PTD requires strict KYC for foreign customers. Activation 15-30 business days. Sanctions screening applies.
For the broader picture across countries, see our guide to international DID compliance & KYC bundles. For the SIP-trunk concept end-to-end, see the DID Number Provider guide.
3. Number types you can route over the trunk
DIDHub supports the standard Myanmar number types over the SIP trunk:
| Code | Type | National dialing | International dialing | Mobile | From |
|---|---|---|---|---|---|
1, 2, 67 | Geographic | 1 XXXX XXXX | +95 1 XXXX XXXX | Yes | $16.00/mo + usage |
Toll-free | Toll-free | Toll-free XXXX XXXX | +95 Toll-free XXXX XXXX | Yes | $50.00/mo + usage |
For a deeper look at how number types differ globally, see DID number types explained.
4. How DIDHub's SIP trunk works in Myanmar
The technical surface of the trunk is standardised; the Myanmar-specific choices are the POP, the codec list, and the failover topology.
Ingress POPs
- Singapore (primary), lowest in-region latency to Myanmar endpoints.
- Tokyo (failover), secondary route used if the primary path degrades.
Transport & security
- TLS:5061 recommended for any production trunk; UDP allowed for legacy.
- SRTP for media via DTLS-SRTP or SDES.
- SIP authentication: digest registration (PBX behind NAT) or IP-ACL (static peering). See SIP authentication.
Codecs
- G.711 a-law (PCMA), the APAC default.
- G.722, wideband HD voice on capable endpoints.
- Opus, for AI voice agents and IP-native softphones.
- G.729, available on request.
For the codec deep-dive, see voice codecs explained.
DTMF
- RFC 4733 (telephone-events over RTP) is the default. SIP INFO and in-band DTMF available for legacy interop on request.
Channel concurrency
- Trunks start at 5 concurrent channels and scale to 200 per trunk off the shelf. Larger requires a custom arrangement.
- Channels are independent of DID count; you can carry 200 numbers on a 10-channel trunk if your concurrent-call peak is 10. See multiple concurrent calls on one DID.
STIR/SHAKEN
- Not applicable. STIR/SHAKEN is a US/Canada construct that doesn't exist in APAC. Trust signals come through national regulator registration and operator-side caller-ID validation.
5. Outbound calling from your Myanmar trunk
Outbound from a Myanmar-allocated DID to Myanmar destinations is allowed within approved use cases. The per-minute economics:
| Destination | Per-minute | Billing increment | Notes |
|---|---|---|---|
| Myanmar landline (geographic) | $0.05/min | 1+1 second | Standard use cases |
| Myanmar mobile | $0.10/min | 1+1 second | Standard use cases |
| International from Myanmar DID | Per destination rate | 1+1 second | See global rates |
Outbound caller-ID rules
- Your outbound CLI must match a DID you've allocated through the trunk. Setting an arbitrary caller ID is rejected at the SBC.
- Origin-based rating (OBR) applies on cross-border outbound, the regulated EEA tier may apply depending on the source carrier.
- For multi-region operators, see origin-based rating savings.
6. Setup in 6 steps
Sign up & submit details
Create a DIDHub account, supply your business details and the intended use case for Myanmar numbers.
PTD compliance review
We coordinate with PTD and our in-region carrier; typical timeline 15-30 business days.
Allocate DIDs & channel capacity
You pick the Myanmar number types you need and how many. Channel capacity allocated at the same time.
Receive trunk credentials
SIP URI (defaults to sip.didhub.io, terminating to Singapore), digest username/password or IP-ACL details, TLS cert verification fingerprint, and your assigned DIDs.
Wire up your PBX or platform
Standard SIP trunk configuration on Asterisk, FreePBX, 3CX, Kamailio, OpenSIPS, or any modern stack. For Teams Direct Routing, Vapi, Retell, or other BYOC platforms, paste credentials into their BYOC config.
Test inbound + outbound
Place a test call to one of your DIDs from a Myanmar mobile or landline; place a test outbound back. Confirm caller-ID resolves correctly, codec negotiates as expected, and audio quality is acceptable.

8. Pricing
Four line items: per-DID monthly rental, per-minute inbound usage on every Myanmar DID (even landline geographic numbers carry an inbound MOU charge in Myanmar), channel capacity, and per-minute outbound. Setup is $0 once PTD paperwork is approved.
Per-DID monthly
| Type | From | Notes |
|---|---|---|
| Geographic (Myanmar city codes) | $16.00/mo + usage | Inbound per-minute applies; standard use cases |
| Non-geographic / national | $70.00/mo + usage | Subject to regulator allocation |
| Toll-free | $50.00/mo + usage | Free for callers; you pay inbound per-minute |
Channel capacity
| Channels | Monthly | Suited for |
|---|---|---|
| 5 | Included with first DID | SMB / single office |
| 25 | $95/mo | Small contact centre, AI agent low concurrency |
| 50 | $180/mo | Mid-size contact centre, AI agent medium concurrency |
| 100 | $330/mo | Large contact centre, multi-tenant SaaS |
| 200 | $580/mo | Enterprise; larger by arrangement |

9. Porting an existing Myanmar number
Existing Myanmar number? Porting timeline is Limited.
- Typical port time: Limited
- Required documents: phone bill + LOA + ID + proof of address (PTD requirements)
- Cost: port-in fee per number; carrier-side fees may apply
For the full porting playbook (US/UK/EU + the global gotchas), see number porting explained.
10. FAQ
Which POP should I connect to for a Myanmar SIP trunk?
Singapore is the recommended primary; Tokyo is the standard failover. Both terminate to Myanmar via in-region carriers.
How long does activation take for a Myanmar SIP trunk?
15-30 business days after KYC documents are accepted (or instantly where KYC isn't required). Provisioning the SIP side itself is hours, not days; the variability is on the PTD/carrier side.
What codecs should I configure for a Myanmar SIP trunk?
G.711a / G.722 / Opus as the negotiation list, in that order. G.711a is the regional default for Myanmar interop.
Can I use my Myanmar SIP trunk with Microsoft Teams?
Yes, via Microsoft Teams Direct Routing through DIDHub's managed SBC. See Teams Direct Routing.
Can I use my Myanmar SIP trunk with AI voice agents (Vapi, Retell, ElevenLabs)?
Yes, BYOC SIP trunk works with every major AI voice platform. Bind specific Myanmar DIDs to specific agents; outbound CLI must match an allocated DID.
How many concurrent calls can one Myanmar DID handle?
The DID is an address; concurrent-call capacity is set by the channel count on the trunk. A 50-channel trunk with 1 DID can carry 50 concurrent calls to that one number; the same trunk with 200 DIDs can carry 50 concurrent calls across any combination of those numbers.
Does STIR/SHAKEN apply in Myanmar?
N/A (regional construct). Trust signals come instead through national regulator registration and operator-side caller-ID validation.
Can I port my existing Myanmar number to a DIDHub SIP trunk?
Yes. Typical Myanmar port timeline is Limited. Required documents vary by number type; contact us for the specific checklist. See number porting explained for the global picture.
What use cases get approved most easily?
Customer service inbound, opted-in callbacks, transactional 2FA, inbound AI voice agents, and Microsoft Teams Direct Routing for registered entities. Cold outbound, unsolicited SMS campaigns, and anonymous-relay setups are routinely rejected.
