Modernize your global voice communications with reliable IP connectivity
Older phone systems and multiple regional carriers can generate unwanted administrative overhead while driving up operational costs. When your business depends on clear and consistent communication, you simply cannot afford dropped calls or rigid infrastructure.
SIP Trunking consolidates your global voice traffic onto a single, highly available Tier 1 IP network. By leveraging our industry leading global Tier 1 backbone, we provide a secure and predictable path for your voice communications. No matter if you leverage your own Private Branch Exchanges (PBX) or a cloud phone system like Microsoft Teams, GTT simplifies the administration of your voice services underpinned by a secure, reliable, global IP backbone.
When legacy voice imposes limits
Old phone systems linger everywhere, often being expensive and slow to flex with business needs. This leaves you with too many fees and a user experience that’s difficult to defend.
- Multiple PSTN connections stack up costs for every branch you support
- Call clarity swings wildly, eroding trust with customers and staff alike
- Wrangling regional contracts fills your finance department’s days with paperwork and vendor noise
- Rolling out service to a new location lags behind your actual business pace
With GTT SIP Trunking, your phone network moves to the cloud era. Everything gets simpler as you can route calls and consolidate oversight, scaling as you see fit.
Choose SIP Trunking to:
- Cut spend immediately by dropping outdated PRI lines
- Management of all your sites from one place, not ten
- Add or reduce calling capacity on demand with no guesswork
- Shield every conversation with private, protected IP connectivity
The GTT difference
Global reach with centralized configuration
Managing a patchwork of regional telecom providers leads to unpredictable costs and inconsistent
service levels. GTT replaces this fragmented approach with a unified managed global solution.
Without GTT
- You manage separate contracts and support teams for every region
- Capacity is locked at each physical location
- Troubleshooting voice quality issues takes days due to fragmented responsibilities
With GTT
- You get a single global provider for all your SIP trunking needs
- You can pool SIP sessions across your entire organization to maximize resource efficiency
- Voice traffic rides an industry leading, global, private Tier 1 IP backbone for superior clarity and low latency
Results
Clear and reliable communication. Your IT team regains hours previously spent managing vendor relationships and disputing local invoices.
Built for business continuity
A reliable voice network is critical for keeping your teams connected and your operations
running smoothly.
Without GTT
- A local circuit failure completely isolates a branch office
- Disaster recovery requires manual intervention and complex call forwarding
- Security policies vary wildly from one regional carrier to the next
With GTT
- Automatic failover routing keeps calls connected during localized outages
- Disaster recovery is built into the network architecture
- Session Border Controllers deployed globally provides consistent security protocols to protect your voice traffic
Results
Significantly less downtime so your employees stay focused on strategic business initiatives instead of inconsistent voice quality solutions.
