Resilient Sip Box - a gateway hardware and software system - VOIP Application Layer Gateway – the device for providing remote objects with telephone communication at accidents on data transmission channels in infrastructures using the IP PBX of different producers.
Properties (as of December 12, 2016)
- fault tolerance and routing
- setup of the local number plan (is not required during the work as a part of Broadworks)
- quality control of communication channels
- support of basic network services
- instruments of diagnostics
- ensuring connection with PSTN
- formation of CDR
RSB provides a basic set of telephone services (CALL, TRANSFER, HOLD, N-WAY CONFERENCE, MOH) and also connection with PSTN. Routing allows to configure access to MG/MN to the directions in case of unavailability of IP PBX, generation of CDR will help to make out bills for the made calls correctly. The device provides up to 200 simultaneous calls at the moment of unavailability of IP PBX.
Routing of calls
Mechanisms of quality control of communication channels allow to redirect in the automatic mode SIP traffic on alternative SIP Proxy or Voice Gateway. The administrator can configure up to 255 different directions, managing timers and thresholds of switching between routes. Setup of subscriber devices is not required, switching happens without interruption of a communication session, is transparent for the subscriber.
Analysis and fault finding
The device is equipped with means of network diagnostics of connections, allows to collect traffic by the tcpdump tool and to save it on the local flash drive for the further analysis. There is a necessary access to statistical information on operation of SIP devices with which RSB, and to system magazines interacts.
Additional functions
RSB helps to localize mechanisms of providing subscriber devices for economy of bandwidth on WAN channels. For these purposes the local flash drive is used and support FTP of protocols/TFTP is provided. Also the device provides DHCP, DNS and NTP services. These opportunities help to localize all IP telephony services, necessary for work, for RSB, exempting network equipment from functions unusual for it.
Fault tolerance
The telephone gateway of fault tolerance of RSB is intended for ensuring communication on remote objects at accidents on data transmission channels in corporate networks of telephony using IP PBX of different producers. Application of a number of engineering solutions allows to provide 99% of availability of service of telephony during the work in a cluster, is transparent for the subscriber to redirect traffic along a better route at emergence of failures in a data network. The device is equipped with effective and convenient remedies for search and fault recovery and also economy of bandwidth that is especially important when using data transmission channels of low capacity. Due to application of a single platform for all line of a lineup the device is cheaper and simpler in expansion.
Development History
2017
The 5-port RSB model is announced
On October 31, 2017 RCNTEC announced 5-port model of the gateway of fault tolerance Resilient Sip Box (RSB) which presentation is planned for November 8, 2017.
The gateway of fault tolerance of RSB allows to render communication services during the periods when contact with servers of cloud automatic telephone exchange is absent because of accidents on data transmission channels. Level of reliability of service increases up to 99.999%.
In addition to increase in number of ports the model of the device supports VPN connections and protocols of TLS/SRTP.
Specification of the device
RSB provides a basic set of telephone services (CALL, TRANSFER, HOLD, N-WAY CONFERENCE, MOH), connection with PSTN. Flexible configuration of routing allows to configure access to MG/MN to the directions in case of unavailability of IP PBX, and generation of CDR will allow to make out bills for the made calls correctly. The device provides up to 200 simultaneous calls at the moment of unavailability of IP PBX.
Mechanisms of quality control of communication channels allow to redirect in the automatic mode SIP traffic on alternative SIP Proxy or Voice Gateway.
The administrator can configure up to 255 different directions, managing timers and thresholds of switching between routes. At the same time any setup of subscriber devices is not required, and switching happens without interruption communications is transparent for the subscriber.
RSB is equipped with means of network diagnostics of connections, allows to collect traffic by the tcpdump tool and to save it on the local flash-carrier for the further analysis. There is a necessary access to statistical information on operation of SIP devices with which RSB, and to system logs interacts.
RSB allows to localize mechanisms of a provisioning of subscriber devices for economy of bandwidth on WAN channels. The local flash-carrier is for this purpose used and support FTP of protocols/TFTP is provided. Also RSB provides DHCP, DNS and NTP services. The present possibilities allow to localize all IP telephony services, necessary for work, for RSB, exempting network equipment from functions unusual for it.
RSB ensures functioning in a cluster configuration, at the same time switching between nodes of a cluster is executed without interruption of the operating connections. Without interruption communications in the mode of a cluster replacement of the system software RSB is possible.
Resilient Sip Box is checked for technology compliance
On May 23, 2017 the RCNTEC company confirmed compatibility of the gateway Resilient Sip Box (RSB) with software environment of BroadWorks.
 | Cooperation of BroadSoft and RCNTEC will help to solve the problems of customers connected with transition from traditional automatic telephone exchanges to cloud. The gateway of fault tolerance of RSB will help providers and their clients to reach higher level of service. Mark Baker, director of business development of BroadSoft |  |
| | Our development completely meets customers needs in reliability and fault tolerance of communication on remote objects. Official confirmation of compatibility from Broadsoft – the recommendation for the Russian and foreign customers who are already using solutions of this company in the business. RSB completely responds a general course of our state to import substitution, and thanks to high competitiveness in the world market can apply also for an export share in the field of IT. Evgeny Novikov, vice president for telecommunications and communication of RCNTEC | |
