Why you might choose ESI’s eCloud + eTeams approach instead

Here are the reasons why using ESI (with its eCloud PBX + eTeams connector) can make sense instead of going “pure Teams”:

1. More advanced telephony features
   ESI’s product page says you get a robust set of enterprise-call-control features: dedicated personal DID numbers per user, global inbound/outbound calling, custom domestic/international dialing based on role, voicemail with visual voicemail, call queues with music-on-hold, click-to-call from docs/emails/websites, flexible call handling (forwarding, transfers, parking). ESI Estech+1
   If your organization has more advanced telephony needs (lots of inbound/outbound, international dialing rules, complex call routing, call-queueing, etc) then this gives you more “PBX-style” richness than maybe the out-of-the-box Teams Phone solution.

2. Flexibility, hybrid deployment, and device support
   ESI mentions that you can keep your existing phone numbers, you don’t need extra hardware, and you can integrate ESI phones, softphones, Teams clients. HubSpot+1
   If your business uses a mix of desk phones, mobile, softphones, remote users, branches — this flexibility may help. Also if you want to preserve your telephony investment (numbers, extensions, maybe some hardware) while still moving to a modern cloud model, ESI may offer smoother transition.

3. Avoid vendor lock-in / migration risk / “all-Microsoft” footprint
   While Microsoft is powerful, some businesses worry about being fully locked into Microsoft’s voice ecosystem (hardware, licensing, carriers, routing). A specialized provider like ESI may give more telco/voice-centric capabilities, more options for routing, carriers, global numbering, etc. For instance one blog says PBX alternatives (with Teams or otherwise) may have less vendor-lock-in risk. Velox Networks+2Spiceworks Community+2

4. Preservation of existing telephony investments
   If you already have a somewhat modern PBX or cloud-PBX (not Teams) with lots of users, numbers, custom dial plans, etc — it may be less disruptive to overlay ESI + Teams than rip everything out and re-build entirely with Microsoft. ESI explicitly says “Deploying eTeams does not require any additional hardware or changes to existing phone numbers”. HubSpot+1

5. Enhanced international / global calling and specialty routing
   ESI markets global inbound/outbound calling, custom dialing based on roles, etc. If your business has more complex geography or call-routing demands, this might be a differentiator

Decision Criteria: What to ask / evaluate

Here are questions to run through to determine which path is right:

1. What are your current telephony features and workflows?

   • Do you use many auto-attendants, call queues, advanced routing, international DID’s?

   • Are you still heavily using desk phones, or mostly softphones/mobile?

   • How many branches/locations, remote/hybrid users, mobile users?

2. What is the state of your legacy phone system?

   • Is it near end-of-life, high maintenance, lacking features?

   • Do you want to remove on-prem hardware entirely, or desire a gradual transition?

3. What are your calling patterns and volumes?

   • How many users place inbound/outbound calls? Is international calling heavy?

   • What are your current telecom costs (monthly PSTN/long-distance/maintenance)?

   • Could a solution reduce costs significantly (e.g., eliminating hardware, moving to cloud, using bundling)?

4. What is your endpoint/device environment?

   • Are users primarily on desktop/mobile? Do they still use desk IP phones?

   • Do you want to maintain desk phones now or move fully to Teams clients?

5. What is your migration appetite/risk tolerance?

   • Would you prefer a “rip-and-replace” approach (full Teams) or a phased/hybrid approach (ESI overlay)?

   • How disruptive can your cutover be? What’s your timeline?

6. What do you want from future growth?

   • Growth into new locations, global expansion, more remote users — which solution scales best for your roadmap?

   • Do you anticipate needing more advanced telephony features (contact center, advanced analytics, complex routing)?

My Recommendation

• If your company is still running a legacy/in-house phone system and you use Teams for collaboration, ESI eCloud PBX + eTeams is likely a very strong fit: it gives you the advanced telephony features you may expect (since you help install systems) and lets you transition to modern cloud while keeping your Teams environment.

  If, on the other hand, you have minimal telephony complexity, mostly internal calls, very few desk phones, and your cost model is simple, then using Teams Phone directly may be more straightforward.

  “Here’s what native Teams gives you — and here’s what ESI overlay gives you if you need more telephony muscle.”

Option 1 — Microsoft Teams Phone (Native Microsoft Solution)

• Overview:
  Turns Microsoft Teams into your phone system. Users make and receive calls directly inside Teams with a Microsoft calling plan or certified carrier connection.

  • Simplified user experience (chat, meetings, calls all in one app)

  • Ideal for businesses already standardized on Microsoft 365

  • Centralized administration through Microsoft 365 portal

  Considerations:

  • Limited PBX-style control (custom routing, multi-site dial plans)

  • Advanced features (queues, call recording, analytics) often require add-ons or third-party apps

  • Porting numbers and retraining staff can add migration cost

  • Dependent on Microsoft for support and carrier management

Option 2 — ESI eCloud PBX + eTeams™ Integration (Powered by Martin Communications)
