Quoting Nathan Littlepage <nathan at iwantka.com>:

> The majority of E911 trunking is CAS MF. I just went through the routine

> > 
> > 911 centers use special lines to connect to the public network either
> > analog/T1 CAMA trunks or digital PRIs
> > 
> > I took a quick look at the new chan_zap.c from the CVS.
> > The implementation seems to be of the analog CAMA trunk kind.
> > CAMA trunks transmit the ANI (more or less Caller ID) as a 
> > formatted MF tone
> > string to the 911 equipment.
