Voice infrastructure that performs under pressure
Poor call quality is one of those IT problems that everyone notices immediately. It's also one of the most avoidable, provided the underlying network and VoIP configuration are done correctly. Mistla treats the voice layer and the network layer as a single system.
Hosted VoIP
Cloud-hosted 3CX running on MC2, Mistla's proprietary IaaS platform. UK-sovereign hosting, 99.99% uptime SLA, 24/7 monitoring through Netminder. No hardware to manage.
SIP Trunk Provisioning
We source, configure and manage SIP trunks from UK carriers. Number porting, DDI allocation, geographic and non-geographic numbers.
Leased Line Procurement
Quality VoIP requires a quality connection. Mistla procures leased lines, FTTP and dedicated ethernet and configures QoS to prioritise voice traffic correctly.
Network Infrastructure
We assess your existing network as part of every VoIP deployment and resolve issues before they affect call quality — not after.
Teams Direct Routing
Connect Microsoft Teams to the PSTN through Mistla's SIP trunks, enabling Teams users to make and receive external calls without a separate phone system.
Contact Centre
Queue management, call recording, real-time reporting, wallboard and AI analytics through 3CX. Included in the licence — no add-ons required.
For NHS and Public Sector
VoIP deployments in NHS and public sector environments require careful attention to data governance, call recording retention policies and network security. Mistla has experience deploying VoIP in these environments and configures systems in line with NHS data security standards.
