Freeswitch in an existing phone network
Hi All, The company I work for currently has quite an extensive phone network which gets carried between old analogue PABXes which also has an interface to IP based phones. All the phones in our office are connected via CAT5 cable using IP, however literally hundreds of phones out in the field (we operate railway infrastructure) are on standard voice analogue phones carried through fibreoptics. Anyway, I would like to use Freeswitch purely for its IVR and TTS abilities and nothing else. So basically I just need it to act like a slave to whatever IP phone network is already out there. I'm a bit worried if I fire up freeswitch it will hijack the phone network! All our phones are accessible via a 5 digit extension. I would like Freeswitch to be behind one of those ... say 12345. If anyone within our phone network dials 12345 then Freeswitch should answer. I guess my question is...how should I go about disabling most of FreeSwitch except it's ability to pick up the phone and speak IVR/TTS and make an outgoing call via the existing phone network? Any general pointers appreciated. Thanks, Oliver Schenk
Hi Oliver, FreeSwitch will do whatever you tell it to do and no more. Here's a few suggestions though - Empty out the default dialplan directory. Don't throw those away, as you may want to reference them as examples, but move them somewhere else. Edit modules.conf.xml and comment or remove any modules that you don't need. This will also save memory and other resources. You can also disable all the SIP profiles except one. Pick one that makes sense (either Internal or External, it doesn't really matter that much), and edit it so that it makes sense with respect to your network. What is your topology? Will you just be setting freeswitch up with a static IP address and having calls sent to it by the main PBX? If that's the case, you can disable a lot of the STUN and uPNP functionality. Tell this profile to bind to the IP and port that the PBX will send the calls to. Then all you have to do, is create a very simple dialplan that will answer an incoming call and perform whatever task you want. You would essentially be starting with a blank sheet, adding just the functions that you want. Hope that makes sense. -Tim Oliver Schenk wrote:

Tim and Joseph make good points. You start with the default configuration and then remove what you do not need. Frankly, the default configuration is just fine for you. FS won't "hijack" your VoIP infrastructure so don't sweat that. It's simply a server sitting on your network waiting for calls. My recommendation would be to do a basic install (see the wiki) and then make one addition to the public.xml dialplan file. Add this simple extension before the closing </context> tag: <extension name="Four-digit extensions"> <condition field="destination_number" expression="^(\d\d\d\d)$"> <action application="transfer" data="$1 XML default"/> </condition> </extension> Press F6 or type "reloadxml" at the FreeSWITCH command line. Now if you throw anonymous calls at this server it will handle four-digit extensions. For example, if you call sip:9999@x.x.x.x:5060 then you should hear music on hold. Call sip:5000@x.x.x.x:5060 and you should hear the demo IVR. (x.x.x.x = FS server IP address) This will let you test a lot of FS features without having to register phones to your FS server, although you are certainly free to do that. Be sure to read the newbie article that I wrote for Linux-Pro magazine last year: http://bit.ly/EpVrv It will help you get up and running quickly. (Note: we switched to git from svn, so we recommend you use git to download the source...) Have fun! -MC On Wed, Jun 9, 2010 at 7:43 AM, Tim St. Pierre < fs-list@communicatefreely.net> wrote:

Whilst on Git, is possible to only 'checkout' certain components of FreeSWITCH as submodules using Git? Thanks Aza On Thu, Jun 10, 2010 at 1:40 AM, Michael Collins <msc@freeswitch.org> wrote:

Hi, Thanks for everyone's reply. Great help. I have a basic IVR going when I dial a given extension. I have managed to clean out most of FreeSWITCH config and I've even written a little javascript file to which my call gets redirected to and it just says a small phrase using flite. I'm looking at buying more professional TTS voices such as Cebstral or Ivona. I'm hosting my freeswitch server in a Virtual Box instance running on Ubuntu Server 10.04. I do my testing from X-Lite running on the host computer. Anyway, that said, I think we will have to stick with Windows because: 1) Our existing railway SCADA server will be windows based. 2) The SCADA libraries are .NET based. 3) I don't want to have separate hardware just to run linux. 4) Our company isn't too good at supporting linux. My problem now is to try to somehow trigger freeswitch to make an outgoing call on demand... The flow of my logic is: 1) A critical alarm occurs on our SCADA system. 2) FreeSWITCH should be triggered to make an outgoing call. 3) Use a pre-recorded WAV or use TTS to tell the callee what the alarm is. The problem: I don't know how to "tell" freeswitch that it needs to make a call and maybe even pass some parameters. Given I have C# and SQL at my disposal, what should I use? A freeswitch javascript program that runs in an infinite loop and constantly scans for new alarms in a database? In the registry? In a folder using files? Using a http request? command line? In other words, how do I trigger a freeswitch javascript program externally? (By the way I tried to use the "managed" module that comes with freeswitch, but it just throws exceptions left right and center TypeInitializationException)... Anyone have some experience?

Just some more info regarding managed C# and ESL. This is what I did: Put the following line in modules.conf.xml: <load module="mod_managed"/> I also checked that the module is in the mod folder. I then started Freeswitch from cmd in windows using "Freeswitch.exe -nonat". There are no errors while it boots. I do however get all sorts of strange IP addresses. My own LAN is a 10.1.1.* network, but I also get IP addresses like: 2010-06-10 21:00:05.530374 [NOTICE] switch_utils.c:195 Adding 172.16.0.0/12 (deny) [] to list wan.auto 2010-06-10 21:00:05.530374 [NOTICE] switch_utils.c:195 Adding 192.168.0.0/16 (deny) [] to list wan.auto 2010-06-10 21:00:05.530374 [NOTICE] switch_core.c:970 Created ip list nat.auto default (deny) 2010-06-10 21:00:05.530374 [NOTICE] switch_core.c:972 Adding 10.1.1.4/255.255.255.0 (deny) to list nat.auto 2010-06-10 21:00:05.530374 [NOTICE] switch_utils.c:195 Adding 10.0.0.0/8 (allow) [] to list nat.auto 2010-06-10 21:00:05.530374 [NOTICE] switch_utils.c:195 Adding 172.16.0.0/12 (allow) [] to list nat.auto 2010-06-10 21:00:05.531374 [NOTICE] switch_utils.c:195 Adding 192.168.0.0/16 (allow) [] to list nat.auto 2010-06-10 21:00:05.531374 [NOTICE] switch_core.c:981 Created ip list loopback.auto default (deny) 2010-06-10 21:00:05.531374 [NOTICE] switch_utils.c:195 Adding 127.0.0.0/8 (allow) [] to list loopback.auto 2010-06-10 21:00:05.531374 [NOTICE] switch_core.c:987 Created ip list localnet.auto default (deny) 2010-06-10 21:00:05.531374 [NOTICE] switch_core.c:990 Adding 10.1.1.4/255.255.255.0 (allow) to list localnet.auto 2010-06-10 21:00:05.531374 [NOTICE] switch_utils.c:195 Adding 192.168.42.0/24 (deny) [] to list lan 2010-06-10 21:00:05.531374 [NOTICE] switch_core.c:1086 Adding 192.168.42.0/24 (deny) to list lan 2010-06-10 21:00:05.531374 [NOTICE] switch_utils.c:195 Adding 192.168.42.42/32 (allow) [] to list lan 2010-06-10 21:00:05.531374 [NOTICE] switch_core.c:1086 Adding 192.168.42.42/32 (allow) to list lan 2010-06-10 21:00:05.531374 [NOTICE] switch_utils.c:195 Adding 192.0.2.0/24 (allow) [brian@templar.ath.cx] to list domains Where do all those IP addresses come from? Why are they there? Ok, next thing I did was open up VS2008 and opened up freeswitch-1.0.6/libs/esl/managed/managed_esl.2008.sln. No problems there. I then hit compile and it worked without any errors. I had the following uncommented: ThreadPool.QueueUserWorkItem(new WaitCallback(InboundMode)); //ThreadPool.QueueUserWorkItem(new WaitCallback(OutboundModeSync)); //ThreadPool.QueueUserWorkItem(new WaitCallback(OutboundModeAsync)); I then hit run and got the following error: An unhandled exception of type 'System.TypeInitializationException' occurred in ManagedEsl.dll Additional information: The type initializer for 'ESLPINVOKE' threw an exception. It breaks here: public ESLconnection(string host, string port, string password) : this(ESLPINVOKE.new_ESLconnection__SWIG_1(host, port, password), true) { } Output: A first chance exception of type 'System.BadImageFormatException' occurred in ManagedEsl.dll A first chance exception of type 'System.TypeInitializationException' occurred in ManagedEsl.dll A first chance exception of type 'System.TypeInitializationException' occurred in ManagedEsl.dll An unhandled exception of type 'System.TypeInitializationException' occurred in ManagedEsl.dll Additional information: The type initializer for 'ESLPINVOKE' threw an exception.

Where do all those IP addresses come from? Why are they there?
Ok, next thing I did was open up VS2008 and opened up freeswitch-1.0.6/libs/esl/managed/managed_esl.2008.sln. No problems there. I then hit compile and it worked without any errors. I had the following uncommented:
ThreadPool.QueueUserWorkItem(new WaitCallback(InboundMode)); //ThreadPool.QueueUserWorkItem(new WaitCallback(OutboundModeSync)); //ThreadPool.QueueUserWorkItem(new WaitCallback(OutboundModeAsync));
I then hit run and got the following error:
An unhandled exception of type 'System.TypeInitializationException' occurred in ManagedEsl.dll Additional information: The type initializer for 'ESLPINVOKE' threw an exception.
It breaks here:
public ESLconnection(string host, string port, string password) : this(ESLPINVOKE.new_ESLconnection__SWIG_1(host, port, password), true) { }
Output: A first chance exception of type 'System.BadImageFormatException' occurred in ManagedEsl.dll A first chance exception of type 'System.TypeInitializationException' occurred in ManagedEsl.dll A first chance exception of type 'System.TypeInitializationException' occurred in ManagedEsl.dll An unhandled exception of type 'System.TypeInitializationException' occurred in ManagedEsl.dll

Unfortunately I have no idea how to fix it!

Hi,
Thanks for everyone's reply. Great help. I have a basic IVR going when I dial a given extension.
I have managed to clean out most of FreeSWITCH config and I've even written a little javascript file to which my call gets redirected to and it just says a small phrase using flite. I'm looking at buying more professional TTS voices such as Cebstral or Ivona. I'm hosting my freeswitch server in a Virtual Box instance running on Ubuntu Server 10.04. I do my testing from X-Lite running on the host computer.
Anyway, that said, I think we will have to stick with Windows because: 1) Our existing railway SCADA server will be windows based. 2) The SCADA libraries are .NET based. 3) I don't want to have separate hardware just to run linux. 4) Our company isn't too good at supporting linux.
My problem now is to try to somehow trigger freeswitch to make an outgoing call on demand...
The flow of my logic is:
1) A critical alarm occurs on our SCADA system. 2) FreeSWITCH should be triggered to make an outgoing call. 3) Use a pre-recorded WAV or use TTS to tell the callee what the alarm is.
The problem:
I don't know how to "tell" freeswitch that it needs to make a call and maybe even pass some parameters. Given I have C# and SQL at my disposal, what should I use? A freeswitch javascript program that runs in an infinite loop and constantly scans for new alarms in a database? In the registry? In a folder using files? Using a http request? command line?
In other words, how do I trigger a freeswitch javascript program externally?
(By the way I tried to use the "managed" module that comes with freeswitch, but it just throws exceptions left right and center TypeInitializationException)...
Anyone have some experience?
Thanks,
Oliver Schenk

Hi Oliver,
FreeSwitch will do whatever you tell it to do and no more.
Here's a few suggestions though -
Empty out the default dialplan directory. Don't throw those away, as you may want to reference them as examples, but move them somewhere else.
Edit modules.conf.xml and comment or remove any modules that you don't need. This will also save memory and other resources.
You can also disable all the SIP profiles except one. Pick one that makes sense (either Internal or External, it doesn't really matter that much), and edit it so that it makes sense with respect to your network. What is your topology? Will you just be setting freeswitch up with a static IP address and having calls sent to it by the main PBX? If that's the case, you can disable a lot of the STUN and uPNP functionality. Tell this profile to bind to the IP and port that the PBX will send the calls to.
Then all you have to do, is create a very simple dialplan that will answer an incoming call and perform whatever task you want. You would essentially be starting with a blank sheet, adding just the functions that you want.
Hope that makes sense.

Hi All,
The company I work for currently has quite an extensive phone network which gets carried between old analogue PABXes which also has an interface to IP based phones. All the phones in our office are connected via CAT5 cable using IP, however literally hundreds of phones out in the field (we operate railway infrastructure) are on standard voice analogue phones carried through fibreoptics.
Anyway, I would like to use Freeswitch purely for its IVR and TTS abilities and nothing else. So basically I just need it to act like a slave to whatever IP phone network is already out there. I'm a bit worried if I fire up freeswitch it will hijack the phone network!
All our phones are accessible via a 5 digit extension. I would like Freeswitch to be behind one of those ... say 12345. If anyone within our phone network dials 12345 then Freeswitch should answer. I guess my question is...how should I go about disabling most of FreeSwitch except it's ability to pick up the phone and speak IVR/TTS and make an outgoing call via the existing phone network?
Any general pointers appreciated.
Thanks,
Oliver Schenk

Bastards lol I figured it out! In your C# projects it will only work if the Platform Target is set to x86. e.g. Go to project properties > Build tab > Platform Target: x86 You need to set this for ManagedEsl and ManagedEslTest if you are trying out the test program!

Just some more info regarding managed C# and ESL. This is what I did:
Put the following line in modules.conf.xml:
<load module="mod_managed"/>
I also checked that the module is in the mod folder.
