支持SIP协议
支持路由和桥接(NAT与NAPT)模型。
TCP / UDP / IP,ICMP,HTTP,DHCP客户端(WAN接口),DHCP服务器(LAN接口),DNS客户端,DNS中继,SNTP,PPPoE协议,FTP,TFTP。
语音编解码器:G. 711(A律/ U法),G。723.1,G 729A / B,G 726,ILBC
NAT穿透:STUN客户,AVS和柚子等,可以通过修改SIP注册端口,HTTP服务器端口,Telnet服务器端口和RTP端口。
支持标准语音功能,如数字来电显示,呼叫等待,保持,转移,不要打扰,前进,在带内和带外
DTMF,咨询热线(摘机自动拨号),禁止呼出。
支持标准的加密和身份验证(使用MD5,MD5-SESS DIGEST)。
支持静音抑制,VAD(语音激活检测),CNG(舒适噪音生成),线路回声消除(G. 168)和AGC(自动增益控制)。
通过TFTP或HTTP提供简便的配置通手动操作(Web界面和Telnet)或自动集中的配置文件。
通过TFTP / FTP和HTTP支持固件升级。
支持系统日志,可以发送网关的事件到系统日志服务器。
每个FXS端口有一个SIP帐号和一个PSTN电话号码。
它可以使用相同的SIP账户2FXS端口,但那个时候,只有一个端口的,可作为被叫,但是,这两个端口可以同时使用作为呼叫者。
但是,当他们使用的不同SIP账户,它可以用作主叫方或被叫方随时。
为生命线端口,默认是要用作PSTN电话关机时1FXS端口。
您可以选择任何FXS端口,通过端口命脉通过拨号不同的拨号前缀切换到PSTN的来电。

Performance and features
Support SIP protocol
Support Bridge and Router (NAT&NAPT) models.
TCP/ UDP/ IP, ICMP, HTTP, DHCP Client (WAN Interface) , DHCP Server (LAN Interface) , DNS Client, DNS Relay, SNTP, PPPoE, FTP, TFTP.
Voice Codecs: G. 711 (A-law/ U-law) , G. 723.1, G. 729A/ B, G. 726, ILBC
NAT penetration: STUN client, AVS and Citron etc. Can modify SIP register port, HTTP server port, Telnet server port and RTP port.
Support standard voice features such as numeric Caller ID Display, Call Waiting, Hold, Transfer, Do-Not-disturb, Forward, in-band and out-of-band
DTMF, Hotline (off hook autodial) , ban outgoing.
Support standard encryption and authentication (DIGEST using MD5, MD5- sess) .
Support Silence Suppression, VAD (Voice Activity Detection) , CNG (Comfort Noise Generation) , Line Echo Cancellation (G. 168) , and AGC (Automatic Gain Control) .
Provide easy configuration thru manual operation (Web interface and Telnet) or automated centralized configuration file via TFTP or HTTP.
Support firmware upgrade via TFTP/ FTP and HTTP.
Support syslog, can send event of gateway to syslog server.
Each FXS port have one SIP account and one PSTN phone number.
It can use the same SIP account for 2FXS port, but at that time, only one of the port can be used as callee, however, both port can be used as caller simultaneously.
But when they used the different SIP account, it can be used as caller or callee anytime.
For the lifeline port, the default is 1FXS port to be used as PSTN phone when power off.
You can select any FXS port to be switched to PSTN as caller through lifeline port by dial different dial prefix.
