By placing OPENSIP in front of Asterisk, we can register multiple
accounts, and we can successfully make call for Outgoing only. But in
case of incoming it fails. 



If two users are registered with asterisk or OpenSIP then the user that
is registered latest is considered to be valid, and he is able to make
calls, other user with earlier registration can not make call.

My point here is in chain_sip.c what are variables or structure that
need to maintain so that we can consider all registered users as active
users.


Thanks!

how to implement CLONED LINE Feature in asterisk

Hey, I want to implement Clone Line feature in asterisk. I am using SPA-2100.
The feature should work in this way.

There are two ports in the SPA-2100 both are registered with asterisk with same 
username/password, and have the same (phone number)






        
        
        
        


        
                
                
                
                
                
                        
                                

                                
                        
                        
                                No
                                one on the phone 
                                
                        
                        
                                One
                                phone in use 
                                
                        
                        
                                Both
                                phones in use

                                Both
                                phones ring 
                                
                        
                        
                                Phone
                                in use receives call waiting notification, 
unused phone rings 
                                
                        
                        
                                Both
                                phones receive call waiting notification 
                                
                        
                
                
                        
                                Outgoing
                                Calls 
                                
                        
                        
                                Both
                                phones can call out 
                                
                        
                        
                                The
                                unused phone can call out 
                                
                        
                        
                                Neither
                                phone can call out 
                                
                        
                
        



 * Inbound:
      - Both ports will ring. Whichever port is picked up first, will field the 
call.
      - Any additional calls that come in would give call waiting notification 
to the first line, and ring the second line.

      - Once the second line is being utilized, all incoming calls will be 
notifications in the form of call waiting beeps.

 * Outbound:
      - You will have the ability to dial out from port one.
      - You will be able to dial a different party on port two.


*** Note ***
         - If you have an active call on port one, and pick up port two, you 
will NOT have the same call that is currently active on port one. The Cloned 
Line will share the same voice mail and will have the same telephone number as 
the original
 telephone line.

  -  The Cloned Line is NOT a second telephone number.  The telephone number 
that is assigned to the second phone port on the device is the same telephone 
number as the number assigned to phone port one. 


In sip.conf
[line1]
username=line1
secret=line1password
type=friend
host=dynamic
context=outboundcalls
mailbox=1...@default

[line2]
username=line2


secret=line2password

type=friend

host=dynamic

context=outboundcalls

mailbox=1...@default


In extensions.conf
[default]
exten => 1234,1,NoOp(About to dial both phones)
exten => 1234,n,Macro(stdexten,${EXTEN},SIP/line1&SIP/line2)
exten => 1234,n,Hangup()

or for trunk
[default]


exten => 1234,1,NoOp(About to dial both phones)

exten => 1234,n,Gosub(stdexten(${EXTEN},SIP/line1&SIP/line2))

exten => 1234,n,Hangup()


then stdexten would be default as comes in the sample configs...

That should be everything you want if you configure the SPA-2100 to register 
line 1 with username line1 and line 2 with username line2...
