Sip:Provider as a Cloud PBX Solution

A cloud PBX is a PBX serving an office or a company, not located inside them but somewhere out there. It’s delivered as a hosted service, typically by telephone companies. No hardware for end customers, only phones.

With the Sipwise’s Sip:Provider PRO, a VoIP ISP can easily provide such feature to his end customers, in particular offices and small companies.The Cloud PBX module is a commercial module you can add on top of your basic Sip:Provider PRO in order to host cloud PBXs with basic functionalities such as IVR, Announcements, Voiceboxes, Call Group, Queues, Phone Auto-Provisioning system, Chat (XMPP), Call Transfers, BLF and Shared Lines support, Call Pick-up.

The ISP just need to create a user the end customer can use to access the web interface and to manage his own cloud PBX directly. He will be able to create extensions, groups, chat buddy list, queue and provision his phones.

Let’s see briefly how it works.


Creating the PBX

The ISP has just to create one special subscriber called Pilot Subscriber, specifying some mandatory values such as the main number associated to the PBX (e.g 431555123, so each 3 digits extension will look like 431555123XXX), the maximum number of extensions can be created and the web credentials for the Pilot Subscriber. That’s all.


Managing the PBX

The office/company IT manager, or the person in charge to configure the PBX, needs to access the web interface ( with the Pilot Subscriber’s credentials and just start to create the extensions number and associates them to each phones:



We support a wide range of brands, such as Cisco/Linksys, Polycom, Yealink, Panasonic, and much more will come.

Once the association is finished, he just need to push and sync the configuration directly to the phone, specifying the phone’s IP address.
Then he can start to create Call Groups, IVR and office announcements and set the office sounds like music on hold or Queue messages. All the phones are now configured and ready to be used. Additionally, for all the PBX extensions, the system will automatically create the chat users, so every employees can see each other and talk together via an XMPP client.
