Voice & connectivity
business internet
The reliable foundation for being reachable.
We design complete voice architectures: telephony platform, PSTN connectivity, carriers, number management and security, both locally and internationally.
Our role
We analyse your current telephony, design the architecture and select platforms and carriers. We assess SIP and SBC integrations and prepare migration, number porting and redundancy. We manage the project and also guide you through installation and technical management.
Everything for reliable calling, from device to carrier.
Users & devices
Softphones, IP phones, mobile, DECT and wireless telephony.
UC & telephony
Microsoft Teams Phone, Zoom Phone and cloud, hybrid or on-premises PBX.
PSTN connectivity
Calling Plans, Operator Connect, Direct Routing, Teams Phone Mobile or Zoom BYOC.
Voice infrastructure
SBCs, SIP Trunking, gateways, SIP routing and interconnects.
Carriers & numbers
Carrier selection, porting, (inter)national number ranges and service numbers.
Continuity & security
Redundancy, failover, monitoring and encryption where supported.
Keep what works
Existing providers, numbers and infrastructure stay in use wherever possible.
Business internet
Advice on fibre, corporate networks, redundancy and QoS for clear voice quality.
Frequently asked questions about voice and connectivity
What is SIP trunking and do we need it?
A SIP trunk connects your telephony platform to the public phone network over the internet. It replaces old ISDN or analogue lines. Whether you need one depends on your platform: with Teams via Direct Routing or with your own phone system usually yes, with Calling Plans or Operator Connect no.
What does a Session Border Controller (SBC) do?
An SBC is the secure link between your telephony platform and the provider. It handles call routing, translates between systems and protects against abuse. An SBC can run in the cloud or on site, depending on your architecture.
Can we keep our current provider and numbers?
Often, yes. With Direct Routing or Bring Your Own Carrier, you can keep using your own provider with Teams and Zoom. Numbers can also be ported to a new provider. We compare the options technically and commercially.
How does telephony keep working during an outage?
Through redundancy in the design: dual connections, multiple SBCs or data centres, and forwarding to mobile or another location if something fails. Which measures make sense depends on how critical reachability is for you.
What does good voice quality require from our network?
A call needs little bandwidth, but it does need a stable connection with low latency and packet loss. Priority for voice traffic (QoS), a good Wi-Fi design and a reliable internet connection make the difference. We advise you on this.
What does Cloud Avenue do for us?
We analyse your current telephony, design the voice architecture, select platform and carriers, and manage the migration and number porting. We also guide you through installation and technical management. You have one point of contact.
