"Pluscloud recently joined CM.com. What we noticed were the short and fast communication lines. Together with the efficient dashboard and the simplicity of the concept, CM.com offers us a SIP Trunking solution that is much more efficient and economical than the solutions of the competition."

Martijn Snels, Founder Pluscloud

"The quality of CM's SIP Trunk is good and certainly comparable to traditional ISDN-based telephony connections. The switch to CM's Voice platform was also easily and quickly implemented."

Sander Kole, Technical Director Takeaway.com

"The price is not only what matters. CM is also a specialist when it comes to smart routing of calls via the best telecom suppliers. The price is OK but the quality of the routing is very high."
