[asterisk-users] Multiple user registration ...

Dear Mauro,

Your requirement seems Clone line feature for asterisk. The same question I've asked here in this group, a months later but could't get well. But actually implemented it now!
It is done using AMI. Here is its basic psudo code.

# ami-event.pl
Connect to AMI
Read the AMI Events 
Parse the events 
If it is registration Event then store the Username/IP/Ports/Technology in Database

# dial plan
run agi script to get all strings eg.
first Device:       SIP/User at 192.168.0.123:5061
second Device:  SIP/User at 10.0.0.150:6060

The complete script is attached.

Hello there!

We are planning to use Asterisk on our VoIP platform, and we are 
spending some brains on a way to provide the following facility: let 
some SIP user (extension) registrate with more than one client (ATA, 
SoftPhone, VoipCelular, etc) - what isn't a problem at all -, initiate 
calls from any of this devices that are registrated with the same user - 
no problems on tests too -, but also receive INVITE requests on "all" 
devices if someone calls this user - yeah... here the thing gets creepy.
The demand is quite simple: let a user registrate with multiple devices 
using the same SIP user on such way that if someone call him, all these 
registered devices will ring and the first to take the call will be "the 
lucky one".
The demand, as I've said, is quite simple and logical (translated to our 
living world), but the reality is a very different history.

On our tests, always is the last registered application/device that 
receives the call indication.
And only the last one.

We are making some tests trying to "kind of deceive" Asterisk on second, 
third, and additional, registrations so it receives from Realtime "fake" 
extensions numbers on such a way that we can use all these fake 
extensions to build a queue dinamicaly (through ARA) and provide the 
desired "ring on all" functionality.
I think this will lead us to lots of SIP sinalization and multi user 
registration problems, but that was the best shot we had here until now.

I would like to know if anyone had the same demand and, maybe, have 
found any viable solution to it.

Thanks and best regards,
