Basically, all the kind of services that are available on the market. We always observe and follow the current trends in technology, trying to react in good time to changing customer demands by enhancing our system and adding new features.
Services can be divided into retail and wholesale:
- PC to phone and PC to PC – using our own SIP based softphone with embedded voip tunnel client which enablesr communication (both receiving and making calls) from behind voip blockades/firewalls, for example from the UAE or other countries where voip ports are closed;
- device to phone i.e. making and receiving calls from SIP or h323 terminals (bidirectional NAT support), full compatibility with all popular brands of soho gateways and IP phones, support for 5 class services, voicemail, waiting message indicator feature, actual balance information on phone’s display and more.
- DIDs/Virtual phone number services – assigning phone numbers from various geographical regions to SIP or h323 devices or softphones. Customers can pick up a phone number directly from the web interface with immediate delivery. The system can work with leading DID providers through their API and/or using own DID numbers stored in a local database.
- Class 5 services – call waiting, call forwarding, follow me – possibility to set forwarding rules conditioned on various events (e.g. busy, no answer, not logged) with different forwarding destinations/phone numbers (possibility to set multiple numbers with different priorities), hold, hold with conversation
- Voicemail – checking voice messages by calling a predefined voicemail number from a softphone or SIP/h323 device or from PSTN through the IVR system (calling cards) or using the callback service. Detailed information about left messages on the web interface. Possibility to record own welcome prompt. Email notification about new voice messages
- Callback services – triggered by SMS, Web or a missed call. Works with DIDs as an access number. Authentication by callerID (ANI) or PIN. DID callback with unique DID associated with each customer and his/her phone number also supported. Manageable through the web interface, possibility to add multiple ANIs per user. Multilingual Interactive Voice Response system (IVR). More on the callback and its variants here
- Calling cards – phone to phone services in which a customer dials an access number first, and is then asked for a PIN (or authenticated by callerID/ANI) and then prompted for a destination phone number. The system comes with its own IP based IVR system that supports several languages (with the possibility to add new), balance announcement, max duration for the call announcement, and also allows you to recharge the account by PIN and register actual ANI during the call, and more. There are several scenarios which can be associated with particular access numbers. Moreover, new scenarios can be added or the existing ones modified by the VoipSwitch administrator as they are programmed in xml format. More on the IP IVR can be found here
- CallShops – a callshop is understood as a place like an internet café or a shop where there are cabins/booths with IP phones from which customers can make calls and then pay for them at a cash desk. The callshop is a windows based application which shows all the cabins and calls that take place. When a customer has finished, the cashier can see the calls made with their details and costs and can charge the customer. The application also allows printing bills. The advantage of this solution is that the callshop application does not require any special hardware as the calls are not sent through it, but instead go directly to VoipSwitch (through the internet connection) and the callshop program exchanges with VoipSwitch only a small amount of data needed for billing purposes. Additionally clients can use softphones installed on PCs or FXS gateways with analogue phones connected, not necessarily IP phones.
- Wholesale termination – bulk voice traffic termination; in this scenario VoipSwitch acts as the traffic controller which on one side collects calls from client gateways or other equipment, authenticates them, and then depending on the routing tables sends the traffic further to termination gateways/gatekeepers. The whole traffic is billed and controlled in real time, the billing supports both prepaid and post-paid accounts types. In addition the media (voice) flow can be set per destination and sent in full proxy mode where all packets go through the switch or in modes where only signalization is sent through the system while the media goes directly between endpoints. The system allows hiding the source and the destination, which is often important, especially if you work as a broker buying and selling traffic from various parties. Additionally, the system offers high flexibility in modifying calls setup, called numbers, and enables you to manipulate prefixes, caller IDs and all other important data before sending calls to the destination. There is also a web interface both for clients and terminators with CDRs (which can be exported to file) and other reports. More on the softswitch’s functionality here.
The H323 protocol is supported by VoipSwitch up to and including version 985.131. Later versions of VoipSwitch do not support this protocol as it is becoming increasingly obsolete.
