asterisk users - Nov 2006 - Ring locally when home or roadwarrior via IAX when away

Hi,

want to have calls directed to internal fixed phones, when my employees 
are home and automatically to their IAX connection when they are logged 
in remotely. How do I do this?

The picture is as follows:

--- HOME ---
- user logged in via IAX with local IP adress
- fixed line should ring
- IAX should not ring

--- ON THE ROAD ---
- user logged in via IAX with an EXTERNAL IP
- fixed line should not ring
- but IAX should be called.

I guess, in short my question reduces to: How do I find the IP adress of 
a specific iax client?

Thanks in advance for the help.

Regards,
Arik

I do not currently run IAX, but SIP clients only. Nevertheless, once
connected, a database entry "appears" containing login info. It seems
to
disappear once the client de-registers, so assuming that IAX does the
same, this could do the trick.


For SIP, the database entry would be "SIP/Registry/sip507" for my
Laptop
which has username sip507 in sip.conf section sip507 (I do not know
which of those two selects the name in the database).

The value in the database looks like 

80.136.xxx.xxx:5060:1800:sip507:sip:sip507@80.136.xxx.xxx;uniq=49XXXXXXXXXXXXXXXXXXXXXXXXXXXX

(with the IP address leading)

With a set of statements like

exten => _5XX,1,Set(IPADDR=${CUT(${DB(SIP/sip${EXTEN})},:,1)})
exten => _5XX,2,GotoIf($["10.0." = "${IPADDR:0:5}"]?100)
exten => _5XX,3,GotoIf($["" = "${IPADDR}"]?100)
exten => _5XX,4,NoOp(Stuff for calling the client via SIP)
exten => _5XX,100,NoOp(Stuff for calling via the phoneline, cause user
is local)

Note that line _5XX,3 is necessary to capture the case of "client not
logged in via SIP at all" - you might as well activate VoiceMail here or
whatever. In my opinion calling the client via SIP right then is not a
good idea :-), hence the GotoIf for calling via the phoneline.

I would try to achieve this with my SIPclient this way, you will have to
find out wether IAX works similarly.
This is untested though, but I hope to give you a useful hint here.

BR,
Anselm

Thanks Anselm. Your solution does work for iax as well, except for some 
typos. I have it working with following set of commands now, in case 
anybody is wondering:

exten => s,1,Set(IPADDR=${CUT(DB(IAX/Registry/arik)|:|1)})
exten => s,2,GotoIf($["192.168.0." =
"${IPADDR:0:10}"]?100)
exten => s,3,GotoIf($["" = "${IPADDR}"]?100)
exten => s,4,Dial(${ARIK_WEB},,t)
exten => s,100,Dial(${ARIK},,t)

Note ${ARIK} contains the fixed line channel, ${ARIK_WEB} the IAX 
channel. arik is the iax login username.
