He can't easily build asterisk because there is no compiler on SME.  If he tries then there is a fair chance that he will break SME if he assumes that it just a version of RHEL & CentOS.   However, as long as you don't mind a potential re-install and you've taken backups then there is no reason not to let him try. You never know he might get something running for you.

Despite what they (Digium) may say, you are not using a very old kernel. CentOS 4 is still supported (although Digium will try to get you to upgrade to CentOS 5 because they do have problems with some of their boards on EL4  & CentOS 4).  Just ask them to send you an email confirming that they no longer support EL4 - it makes them go very quiet and it will give you a chuckle if nothing else). 

Your dealer is correct, SARK is not common compared to FreePBX and trixbox, however it is still just Asterisk.  SARK does NOTHING different in the asterisk files to any of the other Asterisk GUI.  Your dealer can change anything he wants in the ZAP/DAHDI configs.  If it helps, you can yum update your SME box and install the latest DAHDI Asterisk and SAIL 2.3.  SAIL 2.3 uses EXACTLY the same Analogue card sniffer mechanics as Tbox/FreePBX/AsteriskNow.  They all use dahdi_genconf.   

If none of that works then you could always ask your dealer to install an Asterisk system of his choosing and demonstrate that EC works with that platform on the phone lines that are giving trouble. 
You never know, it just might be a CentOS 4/5 thing after all.

After speaking to Digium and emailing them the versions of the kernel, Asterisk and DAHDI I am using plus my reasons for them not trying to upgrade the kernel etc. this is what the said in the reply:

Del,
That version of DAHDI you're installing is insufficient.  We do not support third party builds (such as the one provided by SARK).  You need to download, compile, and install the latest DAHDI release candidate, currently DAHDI 2.2.1-rc2.  Let me know if you need any help doing this.

So does anyone know if DAHDI 2.2.1-rc2 will work with SARK and the current SME kernel? Thanks.

OK - first things first

We do not support third party builds (such as the one provided by SARK).

We don't provide Asterisk builds; the Asterisk rpms you are using are provided by ATrpms.   I don't know if Digium support ATrpms builds or not but from the blanket statement, it sounds like they don't (even tho' just about everyone who runs Asterisk on RedHat/CentOS uses them). 

You can install Dahdi-whatever-release-they-recommend on SME but you will need to install gcc, the kernel sources and various other stuff before you can compile it.    It isn't hard if you know what you are doing but it can be a bit daunting if you haven't done it before.  If you look at this thread...

... it shows you how to compile 1.6 Asterisk and dahdi-2.2.0.  The principle is the same for asterisk 1.4, you just need to download the 1.4 source instead of 1.6.  You can find all of the source files on Digium site at www.asterisk.org.

New page up on the wiki showing how you might install Asterisk & DAHDI from sources for anyone who wants to do it.
