CLASSOUND: Make First-Class International Calls, Securely in the Cloud
CLASSOUND - International calling

International businesses need an international unified communications solution. Even when you’re only placing national calls, it’s essential that your communication service is flexible and reliable enough to support all your operations.

For multi-site companies, unified communications as a service on its own can’t sufficiently enable business processes. On top of VoIP calling services and UCaaS, these businesses need to reliably access international telephone lines and global call forwarding. Many phone, SIP trunk and VoIP services attempt to address this issue, but most of them end up creating issues instead.
Using most SIP trunking services, your business is stuck with:
On top of all these problems, most SIP trunks do not provide effective failover or fax support on a global level. Furthermore, these VoIP SIP trunks do not offer any support for HD audio.

Stop wasting time on ineffective calling apps and solutions!

Whether you’re calling locally or internationally, you need a trunk built to handle your phone traffic. Learn about the benefits of an embedded VoIP Carrier:
