我正在尝试为给定号码的传入/传出创建拨号计划:
+xx XXX [xxxxxxxxx|xxxxxxxx]
我已经在sip.conf中配置了我的服务提供商信息
[sipprovider]
type=friend
secret=xxxxx
defaultusername=xxxxx
host=xxx.xx.xx.xxx
dtmfmode=rfc2833
canreinvite=no
disallow=all
allow=ulaw
allow=alaw
allow=gsm
insecure=port,invite
;fromdomain=xxx.xx.xx.xxx
context=default
nat=yes
现在，我想创建入局/出局中继，我的分机允许拨打国际电话和给定号码的入局电话。
+xx XXX [xxxxxxxxx|xxxxxxxx]
[default]
switch => Realtime
exten => 55,1,Verbose(1,Echo test application)
exten => 55,n,Dial(SIP/sipprovider/0091XXXXX99999@sipprovider); Here is the outbound call, the exact dialstring depends on outgoing provider and channeltype
exten => 55,n,Hangup()
显示:打电话…VM Play: Person you are calling is unavailable

基本上拨号字符串可以是'SIP/devicename/extension'或'SIP/username@host'格式。SIP/sipprovider/0091XXXXX99999@sipprovider错误
"Retransmission timeout reached"表示星号尝试向sipprovider发送INVITE，但是sipprovider的SIP端口(5060 UDP)不可访问。您可以在SIP调试中看到。
