CallerID name lookup in OpenERP for Asterisk IPBX
|
|
|
|
When executed from the dialplan on an incoming phone call, it will lookup in
|
|
OpenERP's partner addresses, 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.address' 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
