AI calling, SMS, and fax embedded inside Microsoft Teams
Microsoft Teams Phone delivers a functional dial tone. DialPhone layers the AI features Teams Phone doesn’t include — AI-drafted SMS, a 24/7 AI Receptionist, Proactive Workflow Automation to log calls into your CRM, 100 percent interaction analytics for contact center, and online fax — all inside the Teams client users already live in. Provisions in hours via Operator Connect, or weeks via Direct Routing for complex enterprise requirements.
Two connection options
Operator Connect (recommended for 85% of deployments)
DialPhone is a Microsoft-certified Operator Connect partner. Provisioning runs inside the Teams admin center — you don’t run SBCs, carriers, or any of the PSTN infrastructure. Microsoft handles the Teams side; DialPhone handles the PSTN side; together they operate as one voice platform.
- Fast — deploy in hours for small rollouts, days for enterprise
- No SBC required — all PSTN connectivity managed by DialPhone on cert Azure
- Predictable per-user pricing — no per-country Calling Plan gotchas
- Global reach — numbers available in 46+ countries
- Microsoft-managed — provisioning and lifecycle inside Teams admin center
Direct Routing (for complex enterprise)
Direct Routing fits customers who:
- Already run an SBC (AudioCodes, Ribbon, Oracle SBC, etc.)
- Have multi-region requirements spanning Operator Connect availability and non-OC regions
- Need specialized call routing (survivable branch appliance, emergency services integration, complex recording)
- Are in a phased migration from a legacy on-premises PBX
DialPhone SBC configuration and support are included in enterprise engagements.
Mixed deployments
Nothing forces a single integration model. A global enterprise can run Operator Connect in the US and UK, Direct Routing in a country without Operator Connect availability, and Calling Plans in a country where DialPhone doesn’t operate — all within one Microsoft 365 tenant. See how this works for global enterprises.

Microsoft Copilot adds AI features inside Teams but they require additional per-user licenses and cover Teams meetings rather than PSTN calls. DialPhone covers the phone system with AI included in the base Advanced plan.
Deployment timeline
- Small team (5–50 users): Operator Connect provisioning in 1 day, numbers ported in 2–5 business days, users trained in 1 hour
- Mid-market (50–500 users): full rollout in 1–2 weeks including Teams admin center configuration, user provisioning via SCIM, and call-flow recreation
- Enterprise (500–10,000+ users): 7-day national rollout with a dedicated Customer Success Manager covering change management, training, parallel-running, and cutover
Supported regions
DialPhone operates in 46+ countries with local regulatory compliance (emergency services, number format, recording requirements). Data residency elections are per-workload: voice recordings can be pinned to EU, call signaling can use global routing, SMS can live in the US — all in the same tenant.
Enterprise compliance
SOC 2 Type II audited. HIPAA BAA available. GDPR, FINRA, PCI-DSS compliant. Microsoft Teams’ BAA covers Teams chat, meetings, and file workloads. DialPhone’s BAA covers voice, SMS, and fax. Together they cover the full unified communications stack for regulated industries.

Pricing
DialPhone pricing applies the same way whether you use the Teams integration or the native DialPhone apps:

Additional Microsoft costs: your existing Microsoft 365 licenses plus Teams Phone Standard (or E5, which includes Phone). DialPhone does not resell Microsoft licenses; purchase those from Microsoft directly.
