The rapid development of Voice-over-IP technology in the early 2000s has lead to fast innovation in the telecom sector. New telecom providers have introduced many innovative services utilizing VoIP technology, such as class 4 service, callshops, broadband VoIP, IP Centrex and others. Because such services are delivered over broadband lines, countries with well established last mile Internet infrastructure tend to adopt faster VoIP services where end-users install VoIP equipment at their premises (e.g. IP Phones), such as broadband VoIP or IP Centrex. Alternatively, countries with limited or expensive last mile Internet infrastructure tend to adopt VoIP services that do not require end-users to install equipment, such as class 4 service and callshops.
The Callshop business model appeals to providers in countries with limited bandwidth or expensive access to the Internet. Callshop services also offer lucrative opportunity in countries with limited number of telecom providers and heavy telecom regulation. Consumers, in such countries, typically do not have access to low cost long distance and international telephony services. Finally, Callshops tend to flourish in areas which attract international tourism. In any of the above cases, Callshop operators can capitalize on VoIP technology and offer competitively priced calling services to any part of the world.
SysMaster offers end-to-end, cost-effective and scalable Callshop solution. The solution features powerful billing, flexible routing, and proven interoperability with VoIP equipment from other leading vendors. Because SysMaster has developed all solution components, callshop owners benefit from reduced integration costs and improved return on investment.
How does the solution work?
- A customer visits the Callshop
- The customer chooses a vacant telephony booth, enters it and places a call by dialing a destination number.
- The call gets connected.
- Upon call completion, the callshop operator presents the customer with an invoice for accumulated call charges.
- Customer pays the callshop operator.
Service provider experience
- When the user picks up the phone and dials a destination number, SM7000 VoIP Gateway sends an authorization request to VoiceMaster® VoIP Billing.
- VoiceMaster® verifies whether a call can be placed from that particular booth and authorizes the call.
- SM7000 passes the destination number to uniSwitch Softswitch and requests routing information.*
- uniSwitch returns to SM7000 the IP address of the remote (termination) gateway and SM7000 connects to it. The remote gateway terminates the call to the destination party.*
- Upon call completion, VoiceMaster® records complete CDR information for the call and makes it available to the operator for billing, reporting and monitoring purposes.
Solution components and requirements
Core elements of SysMaster's Callshop Solution include:

- SM7000 VoIP Gateway, a carrier grade gateway that provides universal IP-PSTN switching, high flexibility and remote feature upgradeability.
- uniSwitch Softswitch**, a flexible VoIP Softswitch that offers routing and reliable peering between VoIP networks.
* In deployments without uniSwitch, VoiceMaster® provides call routing information.
** uniSwitch is required for high volume callshop implementations.
