Argyll & Holler
Cloud Voice Solutions
Argyll have partnered with Holler Technology, the leading provider of cloud voice solutions to the flexible space industry, to deliver a feature-rich and competitively priced solution to your business, whichever Argyll building you’re based at.


Post-pandemic the requirements of businesses for voice has changed dramatically.
Flexible working has become standard for most businesses and embracing the adage “work is a thing you do, not necessarily a place you go to” has never been more relevant. We all now work on multiple devices across multiple locations and on multiple platforms (apps). You’re probably already using a mixture of mobile, Microsoft Teams, email, WhatsApp, FaceTime, iMessage, SMS etc. Now you can unify your comms for all your staff with one platform.
CallSwitch One, from Holler Technology, offers a simple, scalable, design with all features included as standard. For a fixed monthly fee of £19.95 + VAT per month per user you get the following benefits:
- Gigabit Colour IP handset with WiFi/Bluetooth with your company logo
- Free UK calls and heavily discounted international calls
- Smartphone app (iOS/Android) and desktop app (Windows/Mac)
- Microsoft Teams integration
- CRM integration (such as Xoho, HubSpot, Dynamics etc.)
- Transcribed voicemails to your Inbox
- Voice recording (FCA and PCI compliance optional)
- One invoice each month from Argyll (flex up or down, no commitment)
- Supported by Argyll (on-site) and Holler (remotely)


Each month Argyll will invoice you for the service and you can flex up or down monthly with no minimum contract term or installation costs. If you require additional licenses for remote staff (ie. no handset, just the apps) these are only £16.95 + vat per month. For additional services such as geographic numbers for other locations, number porting, FCA or PCI-compliant voice recording etc. please call or email us on the details below.
