Frequently Asked Questions about VoIPSwitch - Part 2

What else do I need apart from voipswitch?

Windows based hosted server is the basic requirement to run VoipSwitch software. The package from does not offer any Hardware, Server or Operating system. So if you want to buy a SoftSwitch you need your own or rented server, all elements should arranged by yourself. The support team will only just install the software on your server and configure the whole system remotely.

Details about some recommended hardware and supported operating systems can be found on Setup can be done at your own place or at a rented server from hosting companies. Many hosting company give better support and high quality internet connection. These companies give service in monthly rent.

With regards to the required internet Bandwidth (B/W) it depends on the number of concurrent calls (CC), used proxy methods and Codec. It takes usually one or two working days to complete the whole process. After completion of installation just need the access permission and details to provide after sales service for one year.

PSTN gateway
In most cases you don’t need any PSTN gateways to run your own hosted VoipSwitch Software as the whole range of scenario can be deployed without having your own equipment. The calls collected from VOIP clients (using Mobile Dialer, PC Dialer, Call back Dialer, Calling card and other calling methods) can be terminated directly through VoIP (Voice over Internet Protocol) carriers and sent to them over Internet. And it does need any physical connected link.

But the only exception is if you want to offer call termination through local PSTN Telecoms and for this the only way to connect is through E1 / T1 connectivity interface (or sometimes GSM or analogue lines). For this kind of implementations you will need a gateway which will provide the required interface. Its role will be limited and it will only convert PSTN to VOIP or VOIP to PSTN. VoipSwitch will control the rest of the process.

The VoipSwitch Softswitch is compatible with all SIP and H323 compliant gateways like Quintum, Cisco and others. Similarly is in origination services like Calling Cards.

The system can work with DIDs, like Virtual phone numbers delivered through internet directly from provider to VoipSwitch. For example if you want to establish a local access number in USA than you need to first rent a local phone number in your desired geographical location (toll free or national number) and have required number of channels associated with the number. When your customers dial the number their calls will be forwarded through Internet to your VoipSwitch which in turn will carry out the programmed IVR scenario.

This IP (Internet Protocol) based approach in the IVR module allows for easy use of multiple access numbers in various geographical locations without high capital expenditures in equipment.

If still for some reasons you have to connect to local Telecom companies in order to setup an access number than the requirement is: you need a gateway with proper physical interface like E1/T1, Analogue, GSM etc.

The gateway does not have to support IVR systems, it should be configured in the way that all incoming calls through PSTN are converted to voip and then forwarded them to VoipSwitch. Then it is VoipSwitch which plays voice prompts, asks for PIN (or authorize by ANI) and carry out the whole procedure.

More about the IP IVR system can be found HERE.

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, voicemail, support for 5 class services, actual balance information on phone's display, waiting message indicator feature and more.

PC to phone and PC to PC - using our own sip based softphone with embedded voip tunnel client which allows for communication (both receiving and making calls) from behind voip blockades/firewalls, for example from UAE, or other countries where voip ports are closed.

Class 5 services - call forwarding, call waiting, follow me - possibility to set forwarding rules conditioned on various events like no answer, busy, not logged with different forwarding phone numbers / destinations (possibility to set multiple numbers with different priorities), hold, hold with conversation.

DIDs / Virtual phone numbers 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 DIDs provider thru their API or/and using own DIDs numbers stored in the local database.

Callback services - triggered by SMS, Web or a missed call. Works with DIDs as an access numbers. Authentication by callerID (ANI) or PIN. Also supported DID callback with unique DID associated with each customer and his/her phone number. Manageable thru the web interface, possibility to add multiple ANIs per user. Multilingual Interactive Voice Response System (IVR). More on the callback and its variants here

Voicemail - checking voice messages by calling predefined voicemail number from 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.

Call Shops - by callshop is understood a place like internet café or a shop where 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 the calls that are taking place. When a customer has finished, the cashier can see the made calls 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 thru it, instead they go directly to VoipSwitch (thru the internet connection) and the callshop program exchanges with VoipSwitch only little data needed for billing purposes. Also as the clients can be used softphones installed on PCs or FXS gateways with analogue phones connected, not necessarily IP phones.

Calling cards - phone to phone services in which a customer dials an access number first and he / she is asked about PIN (or authenticated by callerID/ANI) and then prompted for a destination phone number. The system comes with own IP based IVR system that supports several languages (possibility to add new), balance announcement, max duration for the call announcement, also it allows to recharge 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 be modified by voipswitch's administrator as they are programmed in xml format. More on the IP IVR can be found here


Wholesale services:
Wholesale Call Termination - bulk voice traffic termination, in this scenario VoipSwitch acts as the traffic controller which on one side collects calls from clients gateways or other equipment, authenticate them, and then depending on the routing tables send 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. Also the media (voice) flow can be set per destination and be sent in full proxy mode where all packets are going through the switch or in the modes where only signalization is sent through the system while the media goes directly between endpoints. The system allows to hide the source and the destination what 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, enables you to manipulate prefixes, caller IDs and all other significant 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.
