- µSBC – Call routing between IP networks
- µSBC Connect – VoIP call routing and data connection via LTE network
The µSBC Line is the right choice for small and medium-sized businesses that use SIP technology in their telephony. Its two models enable rotary calls between VoIP networks, solving issues of transcoding and survival, in addition to fallback and security.
Main benefits of the µSBC
Routing and fidelization
Control of telephony charges through configuration of routing by prefixes and/or by fidelization with carriers. It also allows for the ranking of the use of routes by priority, as well as the modification of source and destination numbers, if necessary.
Transcoding: for conversion of codecs
The µSBC has the capacity for up to 28 simultaneous SIP calls, with all of its SBC resources active, using the G.711 codec. It is compatible with and performs transcoding for G.729 according to the table below:
Route failover and Survivability: telephony guaranteed
In case of failures, the µSBC is prepared to maintain continuity of communication. In the event of a failure with a VoIP carrier when the route failover resource is enabled, the unit ignores the route that the server is using and searches for another compatible route. When an IP PBX becomes unavailable, the enabled SAS feature allows the µSBC to assume the basic functions of the IP PBX, such as the completion of outgoing and incoming external calls, calls between extensions and call transferring.
SBC: Network security
The SBC isolates the client’s voice network from the VoIP carrier network or the Internet, thus providing the SIP network with security through data encryption. This way it protects the communication sessions from interception by third parties on all calls simultaneously.
Other important security features that are available include register authorization, call blocking by destination and source to protect against fraud, and masking of topology, among others.
In order to further innovate in the VoIP Telephony market, we designed µSBC Connect – the first SBC device with an LTE data interface. The model has an LTE modem (LTE WAN) embedded in the board, with an external antenna and input for two SIM cards. Only one SIM will be active at a time, the other is on standby and can be activated on demand by the user, or as defined in the business rules.

Application Model – µSBC
Connection of IP PBX with VoIP Internet Carrier
In this scenario, the µSBC connects to the local IP PBX server, with two VoIP Internet carriers, with all security resources.
