Voice processing capability is the most important requirement and measurement for all trunking gateways. WSS100-TG configured with one to four T1/E1 interfaces can maximally process 120 simultaneous VoIP calls. WSS100-TG embeds powerful DSP technology which possesses 4800 MIPS processing power, for full load voice processing to support CODEC (G.711, G.729A, G.723,iLBC,GSM), echo cancellation (G.168), DTMF relay (RFC2833), and fax relay (T.30, T.38) etc.
WSS100-TG supports all kinds of features to satisfy various application requirements. Features include: Calling/Called Party Number Translation, Routing Selection, RADIUS Billing Interface, Second Stage Dialing and Ring-back Tone, DTMF Auto Dial, Tone Detection, RTP voice Proxy (for NAT traversal), T.38 Fax Relay. WSS100-TG supports ISDN PRI and SIP protocols and it is the ideal PSTN trunking gateway for IP phones, PC phones and PBX bridge to VoIP services.
The WSS100-TG supports use-wide ISDN PRI connections to class 4/5 switches such as those offered by Nortel, Lucent, Alcatcl, Siemens, Huawei, ZTE and others. It also supports network-side ISDN connections to ISDN PBXs and supports features such as Caller ID and Direct Inward Dialing.
The WSS100-TG supports wide array of the SIP inclustry standards that enable it to interoperate with SIP-based application servers, media servers and large variety of IADs.
Like other WSS series VoIP products, WSS100-TG has the Web GUI and text configuration interfaces to upgrade, maintain, download log files and collect statistics remotely.
