安装好asterisk之后，开始进行配置，添加了一个sip_additional.conf配置文件
sip配置文件如下：
sip.conf
################################
[general]
bindport = 5060
bindaddr = 0.0.0.0
disallow = all
allow = ulaw
allow = alaw
context = from-sip-external
callerid = Unknow
tos = 0x68
#include sip_additional.conf //在sip.conf中包含了sip_additional.conf的配置
###############################
sip_additional.conf
###########################
[1001]
type = friend
secret = 1234
record_out = Adhoc
record_in = Adhoc
qualify = yes
port = 5060
nat = yes
mailbox = 1001@device
host = dynamic
dtmfmode = rfc2833
dial = SIP/1001
context = incoming
callerid = device<1001>
###########################
配置好了之后重新加载，然后配置SIP终端
通过asterisk发现已经注册上了
命令如下:
asterisk -c ；进入控制台
*CLI>sip show peers
Name/username Host Dyn Nat ACL Port Status
1001/1001 10.10.16.37 D N 5060 OK (102 ms)
