SV1.5 Has Reached End of Life
If your business or school is still running SelectVoice SV1.5, it is time to plan your upgrade. SV1.5 is now end of life, which means no further feature updates, security patches or long-term support. Staying on an unsupported platform exposes you to compliance risk, downtime and missed productivity gains.
The good news: the move to SV2 is straightforward, and the new feature set is genuinely worth the upgrade - especially if your team lives in Microsoft 365 and Teams.
Why Upgrade Now
-
No more security patches on SV1.5, leaving your phone system increasingly exposed.
-
HD voice is now standard, so every call sounds noticeably clearer.
-
Resilience and high availability features protect you from outages.
-
Modern admin tools drastically reduce day-to-day management overhead.
The Most Compelling SV2 Features
1. Deep Microsoft 365 and Teams Integration
This is the headline upgrade for most customers. SV2 stops treating Microsoft as a separate world and pulls it into your phone system.
-
See Teams presence from your phone - check whether a colleague is free, busy or in a meeting before you call them, directly from your handset or softphone.
-
Single sign-on with Microsoft 365 - staff log in with the same credentials they already use, removing yet another password to manage.
-
Auto-sync of users and groups from Microsoft 365 - new starters and leavers flow automatically into the phone system, so directories stay accurate without admin effort.
-
Launch Teams calls from SV Manager - one click to start a Teams call without bouncing between apps.
The outcome: less context switching, fewer missed calls, and an admin workload that drops noticeably from day one.
2. HD Voice on Every Call
SV2 enables HD voice across all platforms by default. For customer-facing teams that means clearer conversations, fewer "sorry, can you repeat that" moments, and a more professional impression on every call.
3. A Modern Softphone and Admin Experience
-
All-in-one softphone brings calls, contacts, presence and call control into a single screen.
-
Refreshed admin dashboard makes everyday changes - users, groups, call routing - far quicker.
-
Mobile-friendly contact and call-forward management, so your people can adjust how they are reached from anywhere.
4. Smarter Call Handling
-
One-click in/out of hours toggle for fast switching at end of day or unexpected closures.
-
User-controlled call group log in and log out, giving your team genuine control of their availability.
-
Reach busy or DND users with messages, so urgent information still gets through.
-
Play recorded messages mid-call - perfect for terms and conditions, disclaimers or compliance prompts.
5. Better Voicemail Visibility and Reporting
-
See exactly when voicemail was triggered and whether a message was actually left.
-
Validate voicemail email delivery so messages never quietly disappear.
-
New Vision3 reporting and wallboard tiles including total forwarded calls, trunk calls by company, cross-midnight reporting and clearer voicemail differentiation.
6. Resilience and Security Built In
-
High availability with a second failover server - no single point of failure for your phone system.
-
Instant SIP trunk control for testing or emergency lockdown.
-
Restrict contact directory access when privacy or safeguarding requires it.
7. Yealink and Device Upgrades (SV2.1)
If you use Yealink handsets, SV2.1 unlocks multi-level BLF, call steal, department call pickup, mid-call WAV injection, contact folders and personal contact lists. Plus support for AX8x WiFi phones, T7 and T8 deskphones, and W75 ruggedised DECT for warehouse, retail and education environments.
8. SelectVoice Purpose-Built for Schools
For schools running SelectVoice, SV2 introduces safeguarding features that simply did not exist on SV1.5:
-
Lockdown Paging plays live or recorded announcements over Yealink speakers, overriding DND and active calls so critical messages always cut through.
-
Emergency OutDial reaches every member of the leadership team with a single number, even if they are off-site.
-
Internal calling continues during internet outages on hybrid and on-prem deployments, keeping staff coordinated when it matters most.
What Happens If You Stay on SV1.5
-
No new features and no security patches.
-
Increasing risk of incompatibility with Microsoft 365 changes.
-
Greater downtime risk with no failover and no path to high availability.
