    Colt aims to help as many customers as possible to migrate swiftly to futureproof solutions – a change which is largely transparent and requires little to no physical adaptation at customer sites, apart from the installation of the Colt Voice Gateway next to the PBX. Customers can retain their access to the ‘PSTN’ with their traditional PBX while Colt ensures the network is future proof across all operators. The service is offered in the following European countries: Austria, Belgium, Switzerland, Germany, Denmark, Spain, France, Ireland, Italy, The Netherlands, Portugal, Sweden and the UK.
