Tutorial: How to install the DEVSTATE-mod

Oct 30, 2008
Is there a need for a tutorial on how to install the DEVSTATE-mod?
I have been searching on this forum, and couldn't find any tutorial on this.

If anyone needs it, I could write it one of these days, as I have successfully installed it on our production server.


To install the DEVSTATE-mod, you need to recompile Asterisk, even though you are only going to use the DEVSTATE-module.

1) You need certain packages, install them with "yum install <package>", as far as they aren't yet installed:
--> make
--> gcc
--> subversion

2) Download the sources. There is only one version of the DEVSTATE-module, but many of Asterisk. Determine your Asterisk version (mine is 1.4.22) and download the sources with:
--> Asterisk: wget http://downloads.digium.com/pub/asteris ... .22.tar.gz //Change version number according to your version.
--> DEVSTATE: svn checkout http://svncommunity.digium.com/svn/russ ... state-1.4/

3) Extract files and put everything in place:
--> tar xvf asterisk-1.4.22.tar.gz
--> cp func_devstate-1.4/func_devstate.c asterisk-1.4.22/funcs/
--> cd asterisk-1.4.22

4) Compile the sources:
--> make clean
--> ./configure
--> make all

5) Have a break, have a coffee... B) Now you should be able to find a file called "func_devstate.so" in the funcs directory. If not, than you will have to repeat step 4 and the break, but this time run "make menuselect" before you run "make all". You should be able to find something called "func_devstate" under option 6, dialplan functions. As for me, it automatically compiled for me, so I don't think you'll run into problemns, but just in case.

6) Copy the module and restart Asterisk:
--> cp funcs/func_devstate.so /usr/lib/asterisk/modules/
--> service asterisk restart

7) Test it:
--> asterisk -r
--> core show function DEVSTATE

8) If you get an error saying that that function is not available, then add the line "USEDEVSTATE=true" to the end of /etc/amportal.conf and restart with:
--> amportal restart

I don't have anything to say about 1.4, but a howto I can write.
I'll post it in the OP.

Thanks for the great howto, seems a lot easier than I was expecting.

I was a little concerned about having to recompile asterisk, not having recompiled anything before... but it looks like you're actually compiling a copy of asterisk in a separate folder independant of the installed copy, and then just grabbing the func_devstate.so file out of it and putting it in to the 'installed' copy of asterisk... is that right?

If so, would that mean that once I do that, I could use that same func_devstate.so file on other exastix installs without having to download, recompile, etc. every time?

Assuming they're the the same version of asterisk of course.

Asterisk has to be compiled in a separate forlder. At least, it's common practice to compile something in a separate folder and, once compiled, move it. So there you are right.

You might want to be careful when copying the module between multiple boxes, especially when the distros are different. But as we are on the Elastix forum, i may assume that all your boxes are Elastix. Then, having the same version of the distro, it could be safe.
But if you could spare a few minutes, then you may be happier with recompiling. It isn't that much work and it gives you some satisfaction when you realize you know the procedure by heart. (As I did after compiling the atl1 driver a couple dozen times. ;) )

Any clearer instructions? like step by step? i know its quite an old thread but if stinger could provide with step by step guide it would be a of a great help.

also want to know few more things stating below:

in our old PBX (Nortel) when a user is already on a call and another one used to call him the phone's display used to show him that person is "on another call" does this DEVSTATE helps bring that feature to Elastix? or its only useful for Day/Night Toggle and DND Toggle? please help as i need this feature so badly.

Thank you.

<<< Moderator's -- I know this is a double posting from " Hardware / Endpoints / Aastra "Visual Message Waiting "
Just seemed to be buried there for a more general searching.
It also includes the Loading instructions for the Aastra XML scripts ... other hardware though may have a similar need for the DEVSTATE loading in elastix v 1.6 and lower. It is included within the Beta v. 2.x.x. >>>

ps. I've set this up in my own text file so I can just grab and go with it as I mess with my test machine << I've also another file for my webmin loading and mondorescue loading ... my fingers always get in the way of typing. :blush:

Hi All,

Added some more ... ¿ replace one of my lines below with the reference from dicko ???? maybe not ???? :blink:


Here's a load of the Aastra XML Script for Elastix , Version 2.2.1
PDF document Doc. No: PA-001009-05-00

This is to get DEVSTATE loaded on to my elastix machine as described on page 11 of the document.

These are the commands I used to enable it in Trixbox CE VMWare."

Still around, but no longer in the Asterisk Business for way over a year.
Therefore my knowledge about it has about completely drained, so unfortunately I can't be of any halp... :S
