The Complete Setup Guide: Phone System Features for Remote and Hybrid Teams
Set up phone systems for remote and hybrid teams with mobile apps, presence management, and security. Learn setup steps, security practices, and troubleshooting for distributed workforces.
The shift to remote and hybrid work has fundamentally changed what phone systems need to accomplish. A system that works brilliantly for a centralised office of 50 people in the same building is inadequate if those people are distributed across the UK, or globally, working some days in the office and others from home. Understanding how these capabilities fit into broader communications is essential—see The Complete Guide to Modern Office Phone System Features: Everything You Need to Know in 2025 for context on the full feature landscape.
Phone system features for remote work teams have evolved from afterthoughts to core functionality. Modern systems assume employees will work from anywhere and build that assumption into core design. This article explores how to set up these features effectively, from initial installation through ongoing optimisation and troubleshooting.
Essential Phone System Features for Supporting Distributed Workforces
Mobile Apps and Softphone Clients
The foundation of remote work phone system support is the ability to make and receive business calls from anywhere, using business phone numbers rather than personal mobile devices.
Mobile Apps
Every major phone system provider offers mobile apps that turn smartphones into business phone extensions. These apps:
- Use Business Phone Numbers: Incoming calls display the business phone number, not the employee's personal mobile. Customers see the business number in caller ID.
- Provide Full Feature Access: All phone system features available from a desk phone are available in the app—call transfer, hold, recording, conference calling, voicemail access.
- Enable Seamless Call Handoff: An employee can start a call on their mobile app, then hand off to a desk phone or vice versa without disconnecting.
- Support Offline Features: Even without internet connectivity, some apps allow access to recent call history, voicemail transcripts, and contacts.
- Include Notifications: Missed call notifications, voicemail alerts, and presence updates keep employees informed.
Desktop Softphone Clients
In addition to or instead of physical desk phones, employees can use software-based clients on computers. These clients function like desk phones but on-screen:
- Call Controls: On-screen buttons for answering, ending calls, transferring, and accessing features.
- Contact Integration: Frequently called contacts display on-screen, allowing click-to-call.
- Call History: Recent calls, missed calls, and call recordings display in the client.
- Presence Status: Shows colleagues' availability status, enabling efficient internal communication.
Presence Management and Availability Indicators
Presence is metadata indicating whether someone is available for communication. Rather than just showing whether a phone is ringing, presence indicates:
Presence Status Options:
- Available: Ready to take calls or messages
- On a Call: Currently unavailable
- In a Meeting: Shouldn't be disturbed unless urgent
- Away: Not at their desk or not currently working
- Do Not Disturb: Explicitly don't want to be interrupted
Benefits of Presence:
- Prevents Wasted Attempts: Rather than calling someone and learning they're unavailable, colleagues see presence and know to call back later or message instead.
- Reduces Interruptions: Colleagues respect "in a meeting" and don't interrupt.
- Enables Asynchronous Communication: Teams can coordinate without real-time connection, important in distributed teams.
Automatic Status Management
Modern systems can update presence automatically based on calendar (if someone has a meeting on their calendar, presence shows "in a meeting"), location, or activity.
Integration with Calendar: When presence syncs with calendar systems (Microsoft Outlook, Google Calendar), presence status updates automatically. When someone has a meeting scheduled, presence becomes "in a meeting". When a meeting ends, presence returns to "available". No manual status management needed; it's automatic.
This integration is surprisingly powerful. Rather than colleagues guessing whether someone is available, accurate presence information enables efficient team communication.
Step-by-Step Setup Process for Remote Employees
Phase 1: Account Provisioning
Before a new remote employee makes their first call, their account must be provisioned:
- Create User Account in Phone System: Add them to the system with their extension, phone number, and feature permissions.
- Assign Phone Number: Either assign them a new direct line or share a main company number with routing to their extension.
- Configure Basic Settings:
- Voicemail greeting (either auto-generated or custom recorded)
- Call forwarding preferences
- Feature permissions (can they record calls? Transfer to external? etc.)
- Integration with CRM or other business systems
- Generate Credentials: Create authentication credentials for app login (username, temporary password) or set up multi-factor authentication if required.
Phase 2: Device and App Installation
Once accounts are provisioned:
- Determine Device Types: What devices will this employee use? Desktop computers, mobile phones, desk phones? Provide guidance on supported devices and OS versions.
- App Installation:
- For mobile: Download from App Store or Google Play
- For desktop: Download from provider's website or use provided installer
- For desk phones: Physical phone delivery or software configuration for IP phones
- First Login: Employee logs in using their credentials. System typically requires MFA (multi-factor authentication), confirming it's the right person.
- Notification Permissions: Grant the app permission to send notifications for incoming calls, voicemail, and messages.
Phase 3: Configuration and Testing
Before the employee takes their first customer call:
- Configure Call Routing:
- Which devices ring when calls arrive? (e.g., mobile app and desk phone simultaneously)
- Which devices ring at which times? (office phone during work hours, mobile anytime)
- Voicemail settings (go to voicemail after X rings)
- Test Call Connectivity:
- Make test calls to ensure audio quality
- Test from different network conditions (office WiFi, home broadband, mobile LTE)
- Verify video functionality works if needed
- Feature Testing:
- Test call transfer, hold, and recording
- Verify contact integration with CRM
- Test any integrations with business software
- Presence Setup:
- Connect to calendar system so presence updates automatically
- Set availability status appropriately
- Explain manual status changes for situations where automatic detection fails
Phase 4: Training and Documentation
Feature Training
- How to make and receive calls from various devices
- How to transfer calls, conference, put on hold
- How to check voicemail and configure voicemail greetings
- How to access call history and recordings (if permitted)
Best Practices
- When to use different devices (mobile for in-transit, desktop when at computer)
- How to maintain professional presence in video calls
- Security practices (secure password, don't share credentials)
Support Resources
- Provide documentation, video tutorials, or quick reference guides
- Establish who they contact for technical issues
- Provide escalation path if basic support can't resolve issues
Follow-Me and Simultaneous Ringing Features: Ensuring Employees Stay Reachable
Follow-Me Functionality
Follow-Me is a feature where calls automatically route to whichever device an employee is currently using.
How it works:
Schedule Configuration: Employee sets up when each device is active:
- 9 AM - 12 PM: Route to office phone
- 12 PM - 1 PM: Route to mobile (lunch break away from desk)
- 1 PM - 5 PM: Route to office phone
Automatic Routing: Calls automatically route to the active device at any time.
Manual Overrides: Employee can manually change which device is active if plans change.
Benefits: Employees can move around and remain reachable. Calls follow the person, not the desk. No need to manually change settings or miss calls.
Limitations: Requires accurate schedule updates if plans change. Doesn't account for unscheduled changes (working from café, travelling).
Simultaneous Ringing
Simultaneous ringing is more aggressive than follow-me. When a call arrives, multiple devices ring simultaneously—office phone, mobile, laptop softphone.
How it works:
Configuration: Employee specifies multiple devices that should ring for incoming calls.
Call Arrival: When a call arrives, all configured devices ring at the same time.
Answer: Whichever device the employee answers on handles the call. Other devices stop ringing.
Pickup Rights: If configured, other colleagues can pick up the call from their devices if it rings too long unanswered.
Benefits: Calls are answered quickly regardless of which device is available. No calls are missed because the "active" device wasn't active.
Potential Issues: Confusion if multiple devices ring in different locations (office and home ringing simultaneously). Battery drain on mobile from constant ringing. Potential customer confusion if call quality varies between devices.
Combining Approaches
Most organisations use a hybrid approach: During work hours, simultaneous ringing between office phone and mobile app ensures calls ring both simultaneously. After hours, mobile-only or voicemail prevents the office phone from ringing. During meeting times, presence integration mutes notifications, but calls still route. Critical calls might use special codes (e.g., pressing * to signal emergency).
Internet Requirements and Bandwidth Planning for VoIP
Remote work phone system quality depends entirely on internet connectivity. Poor connectivity causes call quality problems, dropped calls, and frustration.
Minimum Bandwidth Requirements
| Scenario |
Bandwidth Required |
Notes |
| Per Call (Standard) |
100 kbps (each direction) |
Minimum for voice calls |
| Per Call (HD Voice) |
150 kbps (each direction) |
Higher quality audio |
| Single Remote Employee |
250-500 kbps |
Comfortable target with buffer |
| 5 Remote Employees |
1.25-2.5 Mbps |
Most broadband handles this |
| 10+ Remote Employees |
2.5+ Mbps |
May need business-grade broadband |
Connection Quality Beyond Bandwidth
Bandwidth is just one factor. Connection quality also depends on:
- Latency (Delay): How long does data take to travel to the provider and back? Latency under 150 ms is ideal. High latency (200+ ms) causes annoying echo and delays in conversation timing.
- Jitter (Variation): Latency should be consistent. If latency varies wildly (one packet takes 80 ms, next takes 180 ms), this causes audio artefacts.
- Packet Loss: If some data packets are lost during transmission, voice quality degrades. Professional internet plans typically guarantee less than 0.5% packet loss; consumer broadband might be worse.
Monitoring Tools: Modern phone systems include network quality monitoring. The system alerts IT if connection quality falls below acceptable levels, allowing proactive intervention before customers notice problems.
Home Internet Considerations
Consumer vs. Professional Broadband
| Feature |
Consumer (Residential) |
Professional (Business) |
| Quality |
Variable |
Guaranteed speeds |
| SLA |
None |
Service level agreements |
| Bandwidth |
Shared speeds |
Dedicated bandwidth |
| Support |
Standard |
Priority support |
Recommendation: Professional (Business) Broadband is recommended for critical remote work. Consumer broadband is often adequate for one or two remote workers but unreliable for larger workforces.
Backup Connectivity
For employees doing critical work, backup connectivity is valuable:
- Primary connection on fixed broadband
- Backup connection on mobile hotspot from phone
- If primary fails, calls automatically route to backup
- Prevents work disruption from internet outages
WiFi Optimisation
- Position employee workspaces away from sources of interference (microwave, other WiFi networks)
- Use 5 GHz WiFi when available (less interference than 2.4 GHz)
- Wired Ethernet connection (via cable rather than WiFi) provides most reliable connectivity
Balancing Security with Accessibility: VPNs, Encryption, and Secure Remote Access
Remote work creates security challenges. Employees connect from various locations on various networks, requiring careful security controls.
VPN (Virtual Private Network) Use
VPNs create encrypted tunnels through which all remote employee traffic flows, protecting data from interception.
When to use VPN:
- Healthcare/Financial/Regulated Industries: VPN use is often required by compliance regulations.
- Sensitive Customer Data: If calls or conversations might include sensitive information, VPN provides protection.
- Untrusted Networks: Employees working from cafés on public WiFi benefit from VPN protection.
VPN Trade-Offs:
Security Benefit: Encrypts all traffic, preventing interception on public networks
Performance Impact: Encryption and routing through VPN server adds latency and uses bandwidth
Complexity: VPN setup requires additional configuration and troubleshooting
VPN + Phone System Encryption: Many phone systems offer end-to-end encryption for calls—the call is encrypted directly between parties, separate from VPN. This provides phone-specific security without needing to VPN all traffic.
Access Controls and Authentication
| Security Measure |
Description |
| Multi-Factor Authentication (MFA) |
Employees must authenticate with two factors (password + one-time code from app or email). Prevents unauthorised access even if password is compromised. |
| Location-Based Restrictions |
Phone system only allows logins from known locations (employee's home, office). Attempts to login from unexpected locations trigger additional verification. |
| Device Management |
Track which devices access the phone system. Require employee devices to have password protection and encryption. Allow IT to remotely wipe devices if employee leaves. |
| Session Timeouts |
Sessions automatically expire after inactivity (e.g., 30 minutes). Prevents unattended devices from remaining accessible. |
Secure Call Handling of Sensitive Data
Even with all security measures, remote employees might handle sensitive data in calls. Best practices:
- Do Not Say Numbers: Rather than reciting credit card or account numbers over the phone (which could be recorded or overheard), use secure transfer methods.
- Screen Privacy: Employees should position screens away from others who might see sensitive information.
- Background Noise Control: Private spaces for calls containing sensitive information prevent nearby people from overhearing.
- Call Masking: Some systems support features that prevent call recording or allow customers to confirm sensitive data without recording those segments.
Troubleshooting Common Remote Work Phone System Issues
Call Quality Problems
Symptom: Calls sound robotic, delayed, or unintelligible.
Causes & Solutions:
Insufficient Bandwidth:
- Check available bandwidth
- Pause other internet usage (video streaming, downloads) during calls
