CallerID name lookup in OpenERP for Asterisk IPBX
When executed from the dialplan on an incoming phone call, it will lookup in
OpenERP's partners, and, if it finds the phone number, it will get the
corresponding name of the person and use this name as CallerID name for the incoming call.
Requires the "asterisk_click2dial" module
available from https://code.launchpad.net/openerp-asterisk-connector
for OpenERP version >= 5.0
This script is designed to be used as an AGI on an Asterisk IPBX...
BUT I advise you to use a wrapper around this script to control the
execution time. Why ? Because if the script takes too much time to
execute or get stucks (in the XML-RPC request for example), then the
incoming phone call will also get stucks and you will miss a call !
The simplest solution I found is to use the "timeout" shell command to
call this script, for example :
# timeout 1s get_cid_name.py <OPTIONS>
See my sample wrapper "get_cid_name_timeout.sh"
Asterisk dialplan example :
[from-extern]
exten => _0141981242,1,AGI(/usr/local/bin/get_cid_name_timeout.sh)
exten => _0141981242,n,Dial(SIP/10, 30)
exten => _0141981242,n,Answer()
exten => _0141981242,n,Voicemail(10@default,u)
exten => _0141981242,n,Hangup()
It's probably a good idea to create a user in OpenERP dedicated to this task.
This user only needs to be part of the group "Asterisk CallerID", which has
read access on the 'res.partner' object, nothing more.
Note that this script can be used without OpenERP, with just the geolocalisation
feature : for that, don't use option --server ; only use --geoloc
