diagramAlvondo is an Internet-based realtime communication network based on SIP, the Session Initiation Protocol. By providing an infrastructure with a high degree of security, we can connect your SIP island or run a SIP network for you, what we call a SIP VPN. We operate a lot of services inside the network and can provide all kinds of services, from basic connectivity over secure connections to advanced IVR services.

In addition to SIP we can build XMPP and WebRTC services that works in cooperation with the rest of our realtime platform.
