The role of Session Border Controllers to deliver secure and interoperable SIP network access and interconnection is increasing since the SIP is becoming increasingly critical for the delivery of innovative multimedia and RCS services.

DATATRONICS is offering the highest performance carrier grade SBCs in the market supporting IMS, VoLTE, IPX, WebRTC and SIP trunking, with advanced routing features that can route traffic based on any SIP header or SIP method.

The SBC can be configured as an Access SBC (A-SBC), Interconnect SBC (I-SBC), or both roles simultaneously depending on service requirements and it supports all commonly used IP signaling protocols including  SIP, SIP-I, SIP-T, Diameter, H.323, MGCP, H.248, MSRP and RTSP.

The SBC also offers full IMS functionality at access and interconnect borders to fully control the SIP, RTP, and MSRP traffic flows that comprise IMS sessions. It implements signaling and media-related IMS.

Summary of the main features:
• Signaling Protocols
o Session Initiation Protocol (SIP): user interface or back-to-back user agent (B2BUA)
o Message Session Relay Protocol (MSRP) B2BUA
o H.323: gatekeeper (GK), gateway (GW), back-to-back GK or GW
o MGCP/NCS: virtual gateway and call agent, back-to-back virtual gateway
o H.248: virtual call agent and virtual gateway
o DNS: application layer gateway (ALG)

• IMS/NGN support
o Proxy Call Session Control Function (P-CSCF)
o Serving Policy Decision Function (SPDF)
o Access/Core Border Gateway Function (A/C-BGF)
o Access Transfer Control Function (ATCF)
o Access Transfer Gateway (ATGW)
o Interconnect Border Control Function (I-BCF)
o Interworking Function (IWF)
o Interconnect Border Gateway Function (I-BGF)
o Emergency Access Transfer Function (EATF)
o Signaling interfaces: Gm, Mw, Ic, Iw
o Diameter interfaces: Rf, Rq, e2, Gq, Rx
o COPS interfaces: Rq, e2
o H.248 interfaces: Ia
• Interoperability
o SIP signaling protocol interworking and mediation
o SIP/SIP-I/SIP-T interworking
o SIP IPv6-IPv4 interworking
o NAT traversal and IP address mediation
o Signaling and dial plan normalization
o Dual Tone Multi-Frequency (DTMF) extraction
