Google Voice 能干什么用？自己动手，按网上抄的步骤做软体电话

我一直用的ATA-GIZMO5-SIPSCORCERY-GV今天停止使用了。早先看了各位专家在这里的讨论，也就准备着这一天的到来。我选择的是用IPKALL来取代GIZMO5。网上找的通用DIAL　PLAN，
Code:

####################################################
######## OUTBOUND CALL FROM GOOGLE VOICE  ##########
####################################################

#Logic for routing outgoing calls.
sys.Trace = false
case req.URI.User
when /^/
 sys.Log(" Dialing USA #{req.URI.User} through Google Voice servicet")
 sys.Log("*****************************************************n")
 sys.GoogleVoiceCall("[e-mail]","GV1_Pass","206XXXXX34","#{req.URI.User}","786XXXXX86")
end

[e-mail] = is your GV email account.
GV1_Pass = GV account Password
206XXXXX38 = IPKall Number with or without the "1", This Number Have
to be registered with Sipsorcery.com.
786XXXXX86
= This is your GV number you want to match in this call, and for this
set. make sure this number does not have a 1 in front or it won't work.
(your GV email account and Password are the ones used for this Number).
#{req.URI.User} = any number you will call using SS, leaved as it or
specified a particular number.

刚才试了一下，可以接收，打出。没有试有无三分钟的限制，我猜应该不会有。
我是门外汉，全盘照搬，希望能对还在调试的熊弟街妹们有所帮助。
