See what our partners have to say about our quality and commitment
“DIDWW played a pivotal role in overcoming several telephony challenges we faced in the APAC region. Their exceptional support throughout—and following—our accelerated rip-and-replace initiative has been unmatched. Furthermore, their user interface streamlines the purchasing and provisioning of new numbers, making the process virtually seamless. As a result, we plan to continue expanding our international contact centers with DIDWW as our primary carrier.”
"For a CCaaS platform provider, like us, quality of communications is so important. We are very happy with DIDWW's DID and voice services, as they are helping make the customer experience in our VCC 360 solution seamless. Making our services more widely accessible from browsers can never compromise voice quality, and DIDWW is a great partner in ensuring this."
“Considering the growth rate of the Teltonika company group, it is important to ensure that the newly appointed employees can easily and efficiently reach our partners around the world. This has been achieved with the help of the DIDWW team by deploying their communications solution across all Teltonika offices in 22 countries.”
“An important part of our customer portfolio is active outside of Belgium, hence we were looking for a unified communications solution to implement across multiple geographies. With customers present in 30+ countries, this partnership has opened doors and possibilities for Cloud Group by expanding our target markets outside of our local presence.”
“Through our strong partnership with DIDWW, we are able to offer reliable and innovative VoIP communication services to our valued customers. With our extended global reach, secure cloud-based solutions, and dedication to customer satisfaction, we can meet unique business requirements, promoting their success and facilitating international growth.”
“Always with the best disposition to serve us, DIDWW has helped us in fulfilling our customer’s needs, when it comes to provide them with the numbering solutions, when most of the time the requests get to us as urgent ones. Apart from everything else, it’s also fun and easy to work with DIDWW.”
“We had a very fast integration with our IP voice system and their accessible and open procedures helped us reach our goals. During our contact center transition from an in-house solution to outsource solution, there weren’t any outages. The onboarding process was simple, fast and with substantial assistance.”
“Virtual numbers and Phone Systems are essential parts of our offering, therefore DIDWW is one of the key components in our infrastructure. They have great support and high quality service. We became a client of DIDWW when we were very small, but still were treated in a proper way and were able to discuss business conditions, which helped our growth.”
“DIDWW has helped to facilitate our migration to the INVADE ‘Dialler as a Service’ model by making it simple and cost effective for us to manage all of our client’s SIP requirements in-house. They share our vision and we value their partnership.”
