mod_skinny

About​

SCCP (or Skinny), is a ToIP protocol used in Cisco products like Cisco IP Phones 79xx.

For more info, see Skinny Call Control Protocol on Wikipedia.

If you use SCCP please test the Patterns Dialplan Configuration halfway down this page and provide feedback at the bottom of this page on how it works. Specifically, will FreeSWITCH recognize variable length dial strings and will it timeout properly as specified by the data provided to the skinny-wait dialplan application. Thanks.

Features​

Implemented​

  • Incoming and outgoing calls (early media supported)
  • Shared lines and multiple calls per lines
  • CallInfo set as early as possible
  • New call made from: OffHook, Softkeys (Redial, NewCall), Stimulus (LastNumberRedial, VoiceMail, SpeedDial)
  • Answering calls via: OffHook, Softkeys (Answer)
  • Holding/Retrieving calls via Softkeys (Hold, Resume) or Stimulus (Hold), with MOH (music on hold)
  • Transfer via Softkeys (Transfer) or Stimulus (Transfer). Blind transfer (with OnHook)
  • Ending call via: OnHook, Softkeys (EndCall)
  • Misc: SoftKeys (Backspace)
  • Handle firmware version request (VersionReqMessage) per device type or per device
  • Patterns for dialed numbers to process (patterns-dialplan and patterns-context)
  • Custom applications can be made using the API and events: See Custom applications
  • Custom Events: See Custom Events
  • API Commands: See API Commands
  • Message Waiting indicator (MWI) on the first line of each device
  • Working on x86 (32-bit) and x86_64 (64-bit)

Footnotes:

  1. The six buttons (msgs, conf, forward, speed 1, speed 2 and redial) have button positions 5 to 10 respectively.
  2. Also tested with Cisco Unified IP Phone Expansion Module 7914: adds 14 definable buttons with working lights. Button number starts with 3 for the 7940 and 7 for the 7960.
  3. Mobile Business Solutions From Cisco and Nokia Downloads

"DeviceTypeId" can be found by issuing the following command on fs_cli:

skinny status profile internal device <your_device>

Building​

There is no additional dependency needed to build mod_skinny. You just need to edit modules.conf (uncomment endpoints/mod_skinny) and run:

make mod_skinny

Also uncomment <load module="mod_skinny"/> in ~/freeswitch/conf/auto_configs/modules.conf.xml so that FreeSWITCH actually loads the module at start time.

Configuration​

  • 192.168.0.2 is the IP of the TFTP server
  • 192.168.0.3 is the IP of the FreeSWITCH server (with mod_skinny)
  • SEP001120AABBCC is the phone id (based on the MAC address)
  • Voicemail/Messages is hardwired in code to dial extension "vmain".

DHCP and TFTP Configuration​

This is widely discussed at voip-info.org (http://www.voip-info.org/wiki/view/Asterisk+phone+cisco+79xx), here is a quick overview.

DHCP​

First, the phone gets its IP address and other network configs through DHCP.

The important setting is the tftp server option

using udhcp (the most lightweight) , this is set in /etc/udhcpd.conf:

opt tftp 192.168.0.2

using ISC DHCP (widely used), this is set in /etc/dhcp3/dhcpd.conf:

option tftp-server-name 192.168.0.2;

TFTP​

There are plenty of TFTP server implementations. In the root of the tftp directory (usually /srv/tftp), put the following files:

FreeSWITCH Configuration​

The configuration is loaded from autolad_configs as usual. The default is:

    <X-PRE-PROCESS cmd="include" data="../skinny_profiles/*.xml"/>

Each profile is put in conf/skinny_profiles. The default configuration should work without modifications.

</profile>

  • If ip="", mod_skinny will listen on all IP addresses. If you want to force IPv6, use ip="::"

  • If ext-autodial is set, the phone will do a ringdown/automatically dial that number when taken off-hook. This is useful for customer service and emergency phones.

  • mod_skinny logs a lot under [DEBUG], every skinny message received or sent. keepAlive and keepAliveAck messages are only logged if profile's debug is >=10.

  • When issuing a reloadxml command, those values are not reloaded. Use skinny profile <profile_name> set <name> <value> instead.

  • You typically don't have to bother about the firmware-version unless your phone asks for it through skinny (most Cisco phones use XML files from tftp). If you have missed one, mod_skinny will complain in the log with the following message:

    [DEBUG] skinny_server.c:1501 Device SEP001120AABBCC:0 is requesting for firmware version, but none is set.

  • The auto-restart param is used when a network interface ip changes. If set to true, the socket will be closed (including all connected listeners) and reopened on the new IP.

Device Configuration​

Devices are set up as users in conf/directory. The critical parameter here is id, which corresponds to the MAC address.

Patterns Dialplan configuration​

This dialplan is used when calling from a skinny phone. The default configuration will allow you to call SIP phones and some tests like the variable info dump to fs_cli (9192).

As all the call process is made on the server, we need a way to know how many digits are necessary to route the call. Executing the dialplan each time a digit is pressed is not correct. An other dialplan context is used to say simply what mod_skinny should do:

Please test on your SCPP/Skinny system and tell us how to improve this module at FS-477 -Authenticate to see issue details

conf/dialplan/skinny-patterns.xml

<?xml version="1.0" encoding="utf-8"?>
<!--
    NOTICE:

    This context is used for skinny to match dialed number

    The special applications:
    - skinny-process tells skinny to process the call (route, set call forwarding, ...)
    - skinny-drop tells skinny to drop the call
    - skinny-wait tells skinny to wait for more digits, falls back to setting in profile if data not provided, and then system default of 10 seconds  
-->
<!-- http://wiki.freeswitch.org/wiki/Mod_skinny -->
<include>
  <context name="skinny-patterns">
    <!--
    Wait for another digit by default
    -->
    <extension name="Default" continue="true">
      <condition field="destination_number" expression="^(.*)$" >
        <action application="skinny-wait" data="10" />
      </condition>
    </extension>

    <!--
	You can place files in the skinny-patterns directory to get included.
    -->
    <X-PRE-PROCESS cmd="include" data="skinny-patterns/*.xml"/>
    
  </context>
</include>

You can select the diaplan context by setting patterns-dialplan and patterns-context in the skinny profile configuration.

Dialplan configuration​

This dialplan snippet is necessary when you need to send a call to a skinny phone. Without this, you will not be able to call your skinny phones!

Add something like this to (Example with 11xx):

conf/dialplan/default.xml

<extension name="Local_Extension_Skinny">
  <condition field="destination_number" expression="^(11[01][0-9])$">
    <action application="bridge" data="skinny/internal/${destination_number}"/>
  </condition>
</extension>

Outgoing Channel Syntax​

Basic form:

skinny/<profile>/<number>

API Commands​

Note: most of the command arguments can be auto completed on CLI by using tab (for example <ring_type>).

USAGE:​

skinny help skinny status profile <profile_name> skinny status profile <profile_name> device <device_name> skinny profile <profile_name> device <device_name> send ResetMessage [DeviceReset|DeviceRestart] skinny profile <profile_name> device <device_name> send SetRingerMessage <ring_type> <ring_mode> skinny profile <profile_name> device <device_name> send SetLampMessage <stimulus> <instance> <lamp_mode> skinny profile <profile_name> device <device_name> send SetSpeakerModeMessage <speaker_mode> skinny profile <profile_name> device <device_name> send CallStateMessage <call_state> <line_instance> <call_id> skinny profile <profile_name> device <device_name> send <UserToDeviceDataMessage|UserToDeviceDataVersion1Message> [ <param>=<value>;... ] <data> skinny profile <profile_name> set <name> <value>​

More​

If you want one more, file a JIRA ticket or, better yet, submit a patch to add the features. The FreeSWITCH developer team has no Skinny systems against which to test.

Custom Applications​

If you want to write a custom application, you can control the phone by using the API. For example:

skinny profile internal device SEP001120AABBCC send UserToDeviceDataVersion1Message sequence-flag=2 '<CiscoIPPhoneText><Title>Hello</Title><Prompt>Amazing</Prompt><Text>This is some text</Text></CiscoIPPhoneText>'

You can also register to event skinny::device_to_user (and others).
