雯雯，问问在广州宽带（无线），手机 （不多）的费用是联通，移动，还是电信便宜。我看得有点晕。

如果用得不多， 不經常使用。那就用電信的。以時間計算，RMB￥0.05/分鐘。 唔用唔使比錢，但都幾慢。我經常搭火車來往深圳廣州，我會在火車上用。但經常3G會down grade去到CDMA2000, 比電話線快一D。碰到down grade, 就要人手斷左線，重新連過，通常都會上返去3G.

如果用得多一D， 當然用聯通啦，用iphone,  有software, 會將iphone變成無線wifi router, 供多個wifi設備上網。比如幾個friend坐埋開會，分別上網， 甘就最抵用了。

    A dirty solution would be achieved by modifying the callback module(http://blog.gramels.info/blog/ar ... erisk-callback.html)

Main idea is to call different number according to incoming caller ID. This call initiates the real callback at another asterisk server.

[checkNum]
exten => s,1,NoOp(Incoming call from # ${CALLERID(num)})

;landline,call ipteluser1
exten => s,2,GotoIf($["${CALLERID(num)}"!= "075512345678"]?6)   
exten => s,3,system(cp /var/spool/asterisk/skelett.call /var/spool/asterisk/skelett.tmp.call)
exten => s,4,system(echo 'Channel: SIP/ipteluser1@iptel' >> /var/spool/asterisk/skelett.tmp.call)
exten => s,5, Goto(sendNote,s,1)

;mobile, call ipteluser2
exten => s,6,GotoIf($["${CALLERID(num)}"!="1380013800"]?10)   
exten => s,7,system(cp /var/spool/asterisk/skelett.call /var/spool/asterisk/skelett.tmp.call)
exten => s,8,system(echo 'Channel: SIP/ipteluser2@iptel' >> /var/spool/asterisk/skelett.tmp.call)
exten => s,9, Goto(sendNote,s,1)

; could be modified after your need
exten => s,10,Dial(SIP/20000,,r)    ; otherwise dial 2000
exten => s,n,Hangup()

[sendNote]
exten => s,1,NoOp(Hangup then callback)
exten => s,2,Hangup()
exten => h,1,NoOp(copy skelett.tmp.call file to /var/spool/asterisk/outgoing)
exten => h,2,system(cp /var/spool/asterisk/skelett.tmp.call /var/spool/asterisk/outgoing)
exten => h,3,Hangup()

用得多都是電信3G便宜! 用聯通3G按KB計, 好易爆表!

When I have time, I shall consider the propsed way to implement it.

For simplicity, whenever I receive calls from your parents with proper caller IDs, your extension will be calls. Whenever you are at home, you may talk for a while and call them using whatever means that you want.

电信什么e家套餐？是有无线宽带，加手机的。现在用移动，广州到深圳的火车一定短线。武汉，天津连都连不上。

角色

是e9套餐。所以普通电话的PSTN电话access number是非常重要，在很多地方网络不太好的时候，而GSM信号是非常好，所以PSTN access number就显得非常重要。

    That's great!

Hangup and call me through iax trunk, possible with SetCallerID command so that I can identify the source of call.
   
What about wap-callback? I think it should work even with 2G phone. Maybe this is another option if PSTN number is not available. For my parent, who are not techo folk, it is mission impossible.

角色

For the ederly, the most convenient to call other relatives who live in other countries like you is to call a local access (telephone) number to reach you. If you are at home, you can pick up the call. If not, your parent will hang up. The call charge for making call is minimal but they can reach you in a very convenient way. For making long conversation, you may tell them to hangup first and you make a call to them directly via other means at more economic way.

From the technology point of view, we may spend some time to explore the real call-back feature using Asterisk.

Qnewbie

From the technology point of view, it might be the first time for caller id relay in Asterisk using a call trunk.

What I want to achieve is not only to let my parent to call me but also to call HK(more frequently). Current solution is my parent calls HK and hangs up after the ringtone, then my sister calls my parent. Sometimes it did not work with this approach and the phone bill is constantly over 200CNY and most of time 300CNY per month. That is why I want callback first and let my parent choose the call destination. The fee to call your number is 0.4CNY per minute from my parent's mobile as I can pay ET263 for 0.08CNY, which one would you consider?

终于在广州加了电信的E 套餐2290元12月4M+固话+手机。有点贵，还没加无线宽带。现在的问题是在哪里加什么稳定的VOIPserver？ SPA3102 还是IP01还有什么稳定的？Asterisk 的工具。ATOM？

Qnewbie

From the posts in this forum, it looks like that IP01 is not stable enough for your purpose. ATOM based asterisk server would be more suitable.

The following information would be very helpful for making automatic outbound calls.
