我試了您介紹用Sipsorcery+ipkall+GV+voipdiscount的方法，其他都沒有問題，隻是不知用什麽GV call back number,我用了我家裏的電話號碼，結果每次家裏的電話響了並接通後才能再接通想要撥打的號碼，如果家裏的電話沒有人接，根本就打不出去。30秒後說無人接聽。
不知是什麽地方的設定出了問題？
下麵是我借用您的Dial Plan. 謝謝。
sys.Log("Log message from default dialplan.")
sys.Log("call from #{req.Header.From.FromURI.ToString()} to #{req.URI.User}.")
AREA_code = "206" # your area code for 7 digits dialling
GV_name = "myemail" # google voice account name
GV_pass = "mypassword" # google voice account password
GV_callback = "homephonenumber" # google voice call back number
SIP_provider = "default" # SIP provider name for international calling
num = req.URI.User.to_s
# re-format telephone number ###
num = num.sub(/^011/,'+') # 011 86 xxx to +86 xxx
num = num.sub(/^00/, '+') # 001 206 xxx to +1 206 xxx
case num
when /^[2-9]d{6}$/ # 7 digits number, add area code
num = "+1" + AREA_code + num
when /^[1]d{10}$/ # 1 206 555 1212, add +
num = "+" + num
when /^d{10}$/ # 206 555 1212, add +1
num = "+1" + num
end
# end of re-format ###
sys.Log ("Final Dial Number = " + num)
case num
# Use Voipdiscount for non US/Canadian numbers
when /^\+[^1]/,/^\+1684/,/^\+1264/,/^\+1268/,/^\+1242/,

sys.Dial(num + "@" + SIP_provider)
else
sys.GoogleVoiceCall(GV_name,GV_pass,GV_callback, num, ".*",1,30)
end
