Flexibel und zuverlässig mit kleinen Hürden bei der Einrichtung
5
eine Erfahrung mit SIP Trunk Flexx ist insgesamt positiv. Es bietet eine gute Mischung aus Flexibilität, Skalierbarkeit und Zuverlässigkeit. Die Einrichtung war zwar etwas komplex, aber nach der Implementierung läuft alles stabil und die Sprachqualität ist hervorragend. Für moderne Kommunikationsanforderungen ist es eine solide Lösung.
