Name lookup in Odoo for incoming and outgoing calls with an
Asterisk IPBX
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 2s get_name_agi.py <OPTIONS>
See my 2 sample wrappers "set_name_incoming_timeout.sh" and
"set_name_outgoing_timeout.sh"
It's probably a good idea to create a user in Odoo dedicated to this task.
This user only needs to be part of the group "Phone CallerID", which has
read access on the 'res.partner' and other objects with phone numbers and
names.
Note that this script can be used without Odoo, with just the
geolocalisation feature : for that, don't use option --server ;
only use --geoloc
This script can be used both on incoming and outgoing calls :
1) INCOMING CALLS
When executed from the dialplan on an incoming phone call, it will
lookup in Odoo's partners and other objects with phone numbers
(leads, employees, etc...), 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 "base_phone" module
available from https://github.com/OCA/connector-telephony
Asterisk dialplan example :
[from-extern]
exten = _0141981242,1,AGI(/usr/local/bin/set_name_incoming_timeout.sh)
same = n,Dial(SIP/10, 30)
same = n,Answer
same = n,Voicemail(10@default,u)
same = n,Hangup
2) OUTGOING CALLS
When executed from the dialplan on an outgoing call, it will
lookup in Odoo the name corresponding to the phone number
that is called by the user and it will update the name of the
callee on the screen of the phone of the caller.
For that, it uses the CONNECTEDLINE dialplan function of Asterisk
See the following page for more info:
https://wiki.asterisk.org/wiki/display/AST/Manipulating+Party+ID+Information
It is not possible to set the CONNECTEDLINE directly from an AGI script,
(at least not with Asterisk 11) so the AGI script sets a variable
"connectedlinename" that can then be read from the dialplan and passed
as parameter to the CONNECTEDLINE function.
Here is the code that I used on the pre-process subroutine
"odoo-out-call" of the Outgoing Call of my Xivo server :
[odoo-out-call]
exten = s,1,AGI(/var/lib/asterisk/agi-bin/set_name_outgoing_timeout.sh)
same = n,Set(CONNECTEDLINE(name,i)=${connectedlinename})
same = n,Set(CONNECTEDLINE(name-pres,i)=allowed)
same = n,Set(CONNECTEDLINE(num,i)=${XIVO_DSTNUM})
same = n,Set(CONNECTEDLINE(num-pres)=allowed)
same = n,Return()
Of course, you should adapt this example to the Asterisk server you are using.
