Summary:                    [patch] Add the immediate=yes option to chan_iax2
Description: 
IAX phones and devices (such as the IAXy) are cool.  When you pick up the
phone, a message is sent (even before you dial), and just like on the DAHDI
FSX devices, code gets executed.

DAHDI has "immediate=yes" so that when you pick up the phone, you get
connected directly to the "s" extension.  This is useful for lobby phones,
elevator phones, manual service (number please), etc.

It was nearly trivial to implement in chan_iax2.c.  I made a deliberate
decision to only implement it for users/friends who authenticate (as any
properly connected phone or ATA would).  Simply add "immediate=yes" in the
friend or user definition, and when you pick up the phone, instead of
dialtone, you go right to extension "s" in the appropriate context.

---------------------------------------------------------------------- 
The 1.4 code and 1.2 code in the area of this patch is essentially the
same, so any backporting is easy.

As for softphones... basically it works for any device which, when picked
up, initiates its IAX connection before sending digits.  Unlike SIP, IAX
has the ability to communicate a call initiation and then send digits one
at a time.  I think most softphones can't be "picked up" and present the
entire dialled number all at once.
