G2V Group transforms their global telecoms with NSL

The Customer

G2V Group is a multi-brand, high-growth recruitment business operating across the UK, EU and US, specialising in technology, engineering, life sciences and government sectors. As they are a people business, telephony is vital to their day-to-day operations and remains their core communication channel across their 25 offices and over 650 consultants.

The Challenge

As G2V grew internationally, its telephony environment grew organically. At its peak, there were three different platforms in operation, this was consolidated into a single 8×8 system. Reducing complexity for not only Support Services but also for Finance too. The challenge was to consolidate everything into a single platform regardless of geographical location. 

Key pain points included :

• Fragmented networks – with three providers serving overlapping countries and brands, there were multiple support cases across multiple networks.
• An expansive team required to manage the different providers.
• Call-quality and number-presentation issues, especially when calling into different European markets under tightening anti-fraud rules.
• No single overview of the network, resulting in surplus devices, unused licences and no clear link between users, sites and cost centres.
• Billing that ran up to two months in arrears, making it hard to see where costs sat or to challenge legacy spend in a high-churn recruitment environment.

When Kevin McDonald, Support Services Delivery Manager, took ownership of telephony cost centres, he described inheriting “an absolute mess,” with the team “fumbling around in the dark” trying to work out where assets and costs lived.

Global migration with zero downtime

G2V asked NSL to take full ownership of its 8×8 estate, moving from a direct 8×8 relationship to an NSL-managed wholesale platform. The brief was simple to state, but complex to deliver:

• Migrate from one 8×8 instance to an NSL-managed 8×8 platform.
• Cover 25 locations and roughly 650 users across the UK, EU and US.
• Deliver the migration country by country, site by site.
• Achieve it all with zero downtime for the end user recruiters.

Alongside this, G2V wanted to:

• Clean up the legacy estate, removing redundant kit and unused licences.
• Tighten cost-centre billing and give finance real-time visibility.
• Maintain the familiar 8×8 user experience so frontline staff could “just come in and pick up the phone” with no retraining.

The Solution

NSL and G2V built the project around a clear and very practical migration playbook. Initial scoping work between Kevin’s team and NSL mapped every office, user and device, and agreed on a repeatable, per-site migration process that had already been tried and tested in earlier work.

NSL’s deliverables included:

• Consolidating three network providers into a single, integrated platform, while maintaining compliance with local number-presentation and anti-fraud rules across Europe.
• Rebuilding the entire 8×8 tenant from scratch within NSL’s managed environment, then porting numbers across without impact to users.
• Executing country-by-country changeovers, often out of hours, coordinating with G2V’s network partner for switch reboots and on-site support where needed.
• In many smaller European and US sites, running migrations remotely with local assistance once the process had been proven.

From the end user perspective,  nothing changed. Recruiters left on Monday using the “old” system and arrived on Tuesday to find the same handset, the same softphone and the same way of working – only now sitting on NSL’s managed instance.

Operationally, the active migration work was delivered in around six weeks.

The Results

The outcome for G2V has been a more manageable and more cost-effective global telephony system.

Benefits include:

• A “much cleaner environment,” with surplus devices and unused licences removed and a far neater 8×8 account structure.
• Detailed and accurate cost centres within an NSL billing platform , giving finance live visibility of where licences and call costs sit across brands, sites and countries.
• Tighter billing, with far less leakage from legacy licences for leavers and the ability for budget owners to spot misallocated costs immediately rather than months later.
• A standardised onboarding/offboarding process, supported by NSL, which has allowed Kevin’s team to improve the efficiencies of licence management and cost-centre alignment.
• Continued compliance with complex number-presentation requirements, ensuring calls originate and “pop out” in-country to satisfy anti-fraud rules while preserving the local presence recruiters need.

Commercially, G2V also achieved savings through the move to NSL’s wholesale model, helping it keep a mission-critical telephony platform competitive in a cost-conscious environment.

Perhaps most importantly, G2V now has a telephony partner that can both navigate the world that is 8×8 and continuously surface new capabilities – from advanced analytics to AI-driven tools – as the business evolves.
