Is it possible to share inbound sip trunk and based on caller ID or pins to configure which asterisk server to forward and respond? Any one has dial plan or scripts to share?

This is a bit complicated but it works fine.  It is a combination of auto-attendant, personal hidden menu (not announced through the handset to the caller) designed by myself and PIN protected IVR.  See if it helps and you understand how to use.
  1. [auto-attendant]  
  2. exten => s,1,GotoIf($[${CALLERID(num)} = 91239123]?bubblestar)
  3. same => n,GotoIf($[${CALLERID(num)} = 92469246]?ckleea)
  4. same => n,GotoIf($[${CALLERID(num)} = 91359135]?yhfung)
  5. same => n,Goto(mainmenu,s,1)
  6. same => n(bubblestar),Goto(hi-bubblestar,s,1)
  7. same => n(ckleea),Goto(hi-ckleea,s,1)
  8. same => n(yhfung),Goto(hi-yhfung,s,1)

  10. [mainmenu]
  11. exten => s,1,Background(mainmenu)
  12. same => n,WaitExten()  
  13. same => n,Hangup()  

  15. exten => 1,1,Goto(viaPSTN,991239123,1)                        ; dial to bubblestar's Mobile via PSTN directly  
  16. exten => 2,1,Goto(viaPSTN,992469246,1)                           ; dial to ckleea's Mobile via PSTN directly
  17. exten => 3,1,Voicemail(3001@default)                                ; Go to voicemail box
  18. exten => 8,1,Goto(IVR,s,1)                                        ; hidden menu for personal dial to IVR
  19. exten => 9,1,Hangup()                                        ; let the caller dials 9 to exit
  20. exten => 0,1,Goto(mainmenu,s,1)                                ; let the caller dials 0 to repeat the menu

    Thanks. look interesting. I did have similar dialplan before but can't use "s" properly.

If "s" is not workable (I think telephony card can accommodate "s" more comfortably), you may explicitly indicate your destination phone number such as home or office number and the like in lieu.

Frankly, telephony card is much stronger in recognizing DTMF and "s" and can handle them in a flexible and proper manner.

For forwarding to the desired Asterisk Server, I don't know whether we should make use of the load balancing capability of DUNDi or not.  If someone knows, please share.

    Agreed. In using purely sip trunk, this are always some minor problems come in and go.

    I will properly use a SIP or IAX command to dial to an extension of other asterisk server.

You have showed a good example to study
作者: ckleea    時間: 2011-9-11 22:26

Still some problems in getting long DTMF keys to accept
作者: bubblestar    時間: 2011-9-11 22:50

Try fine tuning your ATA as well such as relaxdtmf=yes to avoid using strict DTMF option.  Echo cancellation adjust can also help to strengthen the recognition of DTMF signal.

Will try again
作者: ckleea    時間: 2011-9-17 10:14

I think I can base on the callerID to forward to any sip/iax machine to do other things. However, this is not a good idea.

I may need to create another IVR menu to do manual transfer based on DTMF keys and PINS.

Auto-attendant 及 IVR menu 可以寫得千篇萬化，最緊要是切合個人使用習慣和喜好及方便易用。但還需要配合實際網路電訊供應商的DTMF訊號是否能融合，才能達致理想的效果。

再者，例如有時候從北京打入可以食到DTMF Keys + PINS，但也不代表從四川、青島或歐美某地方打入來的電話也一樣食到DTMF Keys + PINS 的。 暫時來說，CallerID 算是比較可靠的辨識媒介了。而且DTMF 訊號技術可能因地區地域不同，有時會導致不同程度的不協調啊。

其實，只要設定幾個主要(重要家人/朋友/親屬) 號碼，轉駁至特定IVR/auto-attendant，提供由自己設定的專項服務，其他人的號碼也可以不需理會，直接接去某條專線或當正常來電看待處理就可以了，不需大費周章。

已試based on callerID forward to different asterisk machines.
