Just write a simple CGI script  (running from the Asterisk server)  which 
looks up the nearest phone from the remote IP address ( $ENV{REMOTE_ADDR} in 
Perl), and inject a suitably-modified call file into the 
folder /var/spool/asterisk.outgoing/ .  The file needs to look something like 
the below example:

-----8<-----
Channel: SIP/$SRC
Context: $CTXT
Extension: $DEST
Priority: 1
CallerId: $SRC
----->8-----

where $SRC = source number, $CTXT = context and $DEST = destination.

NB, create the file in /tmp/ first then mv it; this way you can be sure 
Asterisk will never try to parse an incomplete callfile.  If doing this in 
Perl, you *may* get away with keeping the callfile under 1 disk block as long 
as $| = 0 on the filehandle, but this is by no means portable.
