Von Beginn an verlief die Zusammenarbeit mit MIXvoip sehr strukturiert und lösungsorientiert. Das Team hat sich Zeit genommen, unsere Anforderungen genau zu verstehen, und daraufhin eine maßgeschneiderte Telefonanlage für uns implementiert. Besonders beeindruckt hat uns die Transparenz während des gesamten Projekts, sei es in der Planung, Umsetzung oder Nachbetreuung. Die Installation erfolgte termingerecht und ohne technische Komplikationen. Unsere Mitarbeiter erhielten eine klare Einführung, wodurch das System sofort problemlos genutzt werden konnte. Seit der Einführung profitieren wir von einer deutlich besseren Erreichbarkeit, stabiler Sprachqualität und modernen Funktionen wie Konferenzschaltungen und Weiterleitungen. Auch die Integration von Homeoffice-Arbeitsplätzen wurde problemlos umgesetzt. Insgesamt hat das Projekt unsere Erwartungen übertroffen und wir würden MIXvoip jederzeit weiterempfehlen.

Mixvoip was easily able to offer a better product than the competitors and installation went super smooth. All involved teams kept me up to date about the progress and delivered within expected timeline. Now costs are down by ~25% with even more bandwidth than before.
