[asterisk-users] Multiple user registration ...

[Mauro Sergio Ferreira Brasil]

Hi Elliot, and thanks for the reply.

I'm not completely sure you've considered that the SIP users registered 
on all devices are the same.
Have you ?

I mean...
How will I use "Dial" command with a sequence of same devices, like: 
Dial(SIP/101&SIP/101&SIP/101), for example ?

That's why we are testing the possibility to create "virtual" devices on 
subsequent registrations, so we can at the end make something like: 
Dial(SIP/101&SIP/101-001&SIP/101-002) if someone dials to SIP/101.
Note: SIP/101-001 and SIP/101-002 don't really exist. They will be 
provided by our ARA driver to allow the multiple device ringing.

Thanks and best regards,
Mauro.
