[asterisk-users] 2 devices using same sip account

[Aaron Daniel]

We use this function regularly (you should see my phone's
dialstring...).  If one phone responds that it's unavailable, the rest
of the phones will still ring through.  In the event that none of the
other phones are answered, the extension is considered unanswered, so
depending on how you program your dialplan, the call will go to the
unavailable voicemail.  If you watch the CLI in this situation, you'll
see Asterisk try all the devices in the group at the same time, and
it'll just bypass any devices that are unavailable.

Also, the problem with multiple phones registering with Asterisk at the
same name is that Asterisk only stores the information about the device
once, and is overwritten with each subsequent register.  If you have a
softphone and a hardphone both registered, whichever one has a faster
re-register rate will win out over the slower one.  The only way around
this is through the call groups, as several people have stated.
