I’m primarily using Asterisk for home use, I’ve played around with versions prior to SVN-branch-1.8-r324685 (the one I’m currently using) but never professionally or seriously. I’ve about 2 years of Linux use as well in a non-serious manner. The primary purpose for my use is for IAX2 trunking around the house and between a friend’s house over our commercial Internet connections. I wanted to start from scratch to really know how everything works and found the wonderful 3rd edition of Asterisk: The Definitive Guide at O’Reilly. I have mainly based my installation off of this. Relevant details below:
Machine: Old scrubtop, Dell Inspiron 6000 (successfully ran 1.6 in the past on this machine to do what I’m doing now)
Linux flavor: CentOS 5.6 32 bit i686
Kernel version: 2.6.18-238.12.1el5
Asterisk Version: SVN-branch-1.8-r324685
Also Important: I’m running as a non-root user. I have edited the group and name in asterisk.conf and chown’d the right directories (I believe). I have also installed visudo so I can execute things like ‘asterisk -r’ as root.
Here is my issue:
I worked my way up to a simple iax.conf and wanted to reload chan_iax2.conf and see if the peers and users were registered, I go to ‘sudo asterisk -r’.
Then, I issue a reload for the chan_iax2.so (*CLI> module reload chan_iax2.so) and it says:
No such module ’ chan_iax2.so’
So then I think to myself: “hmmm, maybe I didn’t include it in the modules conf file”. I go back to modules.conf and simply have only autoload=yes for [modules]. I try again to reload the IAX2 channel at the asterisk console. Nothing.
I reboot the box and start up asterisk again. Nothing. I think to myself “wtf here” and I hunt down where the modules are located. I head over to /usr/lib/asterisk/modules to verify that it contains chan_iax2.so It does. I get angry. Bourbon. Angrier. Sleep.
So, I thought I would pop over here and throw it out to the guys who are at the top where the air is crisp. Please let me know if I’ve left something out. I’ll answer your questions as promptly as I can. Oh, I’ve also checked out the errata section for the book on O’reilly site and searched Google for known issues but haven’t been successful yet. Thank you in advance for your help, or your pointing me to the right direction.
First thing should be to figure out more details about what exactly is happening when You try to load chan_iax2.so.
So just edit Your logger.conf to contain at least the line
Now You should start Your asterisk (assuming autoload=yes in modules.conf).
After the start You may just exit the asterisk process (probably after trying Your module reload chan_iax2.so again) and have a look at Your file /var/log/asterisk/full. You may grep it for iax2.
If You’re a lucky guy, these messages You’ll find there will lead You already to the solution. If not, feel free to post this log here and maybe we can assist You.
That’s actually some good advice and I should have thought logger.conf to begin with. Foolish of me not to. I suppose I was hoping that someone would have said ‘aha’ and knew right away. Don’t let me seem ungrateful, I will include below (it did find an error but I wasn’t able to correct it straight away because I’m unsure of what it means).
First, in the grep’d out section and then the full file in case someone needs to glean more from it. I really appreciate the help. I don’t frequent forums often and if this is too nooby a question I apologize.

Beside a lot of errors, there’s one of primary interest:
This missing module should IMHO be the reason for
causing chan_iax2.so to fail.
As You did compile manually You chould check, why this specific module is absent. Just make sure to have a fresh checkout of the asterisk-Sources (best is to use a official release as 1.8.5) and make a configure and make menuselect and look what happens.
It seems that the installation You actually run is somwhere corrupted …
Indeed, most of what I’ve Google’d to present have led me to some sort of errors at the time of compilation. I’ll have to do some checking into it (obvious statement). I’ll post what I come out with here.
I am using asterisk 1.8.5, I have got the same problem. My asterisk is working fine, the sip phones can call to asterisk but when i start asterisk, it opens successfully with the following errors

I visit these locations in /usr/lib/asterisk/modules/
The file i.e. res_crypto.so is not in this folder and chan_iax2.so is their in this folder.
abw1oim you said that installation is corrupted, So, can i download the above missing file and placing the file into the specified folder, does this help ?
Your response will be very grateful, waiting for your immediate response,
