This script tests telephone lines using the following algorithm:

He dials the number for verification and makes extension dialing of the extension number
waits for a response in the form of a dtmf signal - 0

Schema works

Shoulder A:

| A pbx (call number,send dtmf) |
| B pbx (ivr speak,ext_number) |
| C pbx (send dtmf 0) |

Shoulder B:

| A pbx (get_dtmf 0) |
| B pbx (relay_dtmf 0) |
| C pbx (send dtmf 0) |

Files projects:

core.py - executable script
autodial.py - module for calling number B
cfg.py - config file
esl.py - esl freeswitsh connector
logger.py - logging module
exten.lua - dialplan
sip.tmp, rtp.tmp - result file

Install

Esl must be configured on freeswitch
a) Install python dependencies - python-ESL, datetime, regex
b) Create a folder for example /etc/zabbix/scripts/test_line
c) Copy the files to test_line and set the patch variable in the cfg.conf
d) If you need monitoring from zabbix
   Create a file /etc/zabbix/zabbix_agentd.d/userparameter_test.conf
    UserParameter = host.line-sip-test, cat /etc/zabbix/scripts/test_line/sip.tmp
    UserParameter = host.line-rtp-test, cat /etc/zabbix/scripts/test_line/rtp.tmp
   Create and configure triggers on zabbix
    name - host.line-rtp-test
    value:
     {host.domain.com:host.line-rtp-test.last()><1
     {host.domain.com:host.line-sip-test.last()><1
e) Dialplan pbx C might look like this:
   exten => ext_number,1,Answer()
   exten => ext_number,n,Wait(5)
   exten => ext_number,n,SendDTMF(0)
   exten => ext_number,n,HangUp()

Configure

a) The cfg.conf file:
   Esl:
    host - ip address pbx
    port - port pbx
    password - password esl
   Sip:
    caller_name - display user agent
    caller_from_uri - caller_from_uri (sip: [email protected])
    caller_contact_user - caller_contact_user (gw + user)
    auth_username - user
    auth_password - password
    location - name context pbx
    module - sofia
    called_number - called A
    gw - gw operator (host.domain.com)
    error_try_sip - number of dial iterations
    error_try_dtmf - number of dtmf iterations
    stageSip - sip monitoring file name for zabbix
    stageRtp - the name of the rtp monitoring file for zabbix
b) The exten.conf file:
   loop - number of dtmf in one dialog
   number_dtmf - extension dialing number
