The Overview
Estate agencies rely heavily on phone communication for enquiries, valuations, and sales coordination. Any disruption to voice connectivity directly impacts staff productivity, customer experience, and revenue. This project improved VoIP reliability for a multi-office estate agency, addressing communication requirements with DrayTek hardware and enhancing call quality, network stability, and daily operations.
The Requirement
The agency required a dependable networking solution capable of supporting their voice-driven operations across multiple locations.
Key priorities included:
- Highly reliable VoIP connectivity to avoid dropped or poor-quality calls
- Prioritisation of voice traffic during busy network periods
- A stable internet gateway to support cloud-based property platforms and CRM systems
- A cost-effective alternative to more complex or expensive networking solutions
Given the central role of phone communication in estate agency workflows, maintaining consistent call quality and uptime was essential to ensuring smooth day-to-day operations.
“DrayTek has made our day-to-day work much easier, especially with so many devices and online systems running at once. We’d happily recommend DrayTek and 5G Communications to any business that needs a reliable, no-fuss networking setup”Ben Mitchell, Parkers Berkshire, Owner/Director
The Solution
To address these requirements, 5G Communications deployed the DrayTek Vigor 2862, part of the DrayTek Vigor 28xx Series of business-class routers.This offered a robust networking foundation with features designed to support reliable VoIP communications.
Key capabilities include:
- Quality of Service (QoS) to prioritise voice traffic over other network activity
- SIP optimisation controls, including the ability to disable SIP ALG
- Improved RTP handling for smoother voice traffic management
- Enhanced handling of fragmented packets, which can impact VoIP stability
Following best-practice VoIP configuration guidance, adjustments were made to SIP behaviour, RTP port handling, and QoS prioritisation to ensure optimal performance for the agency’s calling systems. Deployment across each office location was straightforward, allowing the network to be configured quickly with minimal disruption to daily operations.
The Conclusion
Following the implementation, the estate agency experienced a significant improvement in call reliability and overall network stability.
Clearer calls and consistent connectivity helped staff manage enquiries, book valuations, and progress property sales more efficiently throughout the day. Reduced downtime also improved the customer experience, ensuring clients could reach the team whenever needed.
For 5G Communications, the deployment also reduced ongoing support requirements as VoIPrelated issues declined. The success of the project strengthened confidence in standardising on DrayTek solutions for similar small and medium-sized businesses that rely heavily on voice communications.

Deployment
“The Vigor 2862 was straightforward to deploy.”
Simple and documented deployment for VoIP‑specific configuration, such as disabling SIP ALG, adjusting fragmented packet handling, and applying QoS.
“We have worked with DrayTek products for many years, deploying Vigor routers, Vigor access points, and switches across numerous SMB and multisite environments.
DrayTek has been a consistent choice where reliability, VoIP optimisation, and cost‑effective connectivity are key requirement.”Andre Mellet, 5G Communications, Technical Director
Challanges
Initial issues were linked to SIP ALG behaviour and fragmented packet handling, which are common VoIP hurdles. Following DrayTek’s VoIP guidance, disabling SIP ALG, adjusting RTP port ranges, and altering handling of fragmented packets all initial issues were resolved these problems fully.
