RE: Asterisk Configuration

Well, thank you Mr. Polite.
 
Now having thought about it further, I thought the truth was that ZTDummy used to rely on UHCI or the RTC to get it's timing.  If you didn't have those, then you were scuppered.  Now that 2.6 has better timing in it, ZTDummy uses that and does not rely on hardware anymore, just the Kernel.
 
But you mentioned that it doesnt' use the Kernel clock on 2.6.13 or higher.  What does it it use as a timing source?

Sorry, but that's complete nonsense. If the system has no Digium hardware with its associated driver loaded, then ztdummy absolutely IS required in order to provide a timing source to the zaptel module. The Linux lernel on its own doesn't know anything about providing timing to zaptel.
 
To Vijay, the answer is that you compile it from source just like you do the rest of asterisk. Download the tarbal for zaptel-1.2.2 (recently released), unpack it into /usr/src/zaptel, then just do:
 
# make all
# make install
# make config
 
The edit /etc/rc.d/init.d/zaptel and change the MODULES and RMODULES lines just to include ztdummy, and none of the hardware drivers.
 
If Slackware doesn't put startup scripts in /etc/rc.d/init.d then you might have to set up the zaptel loading by hand.
 
There is no need to recompile the kernel, nor to change its clock rate, since ztdummy doesn't use the kernel clock on 2.6.13 or higher.
 
Cheers
Tony

Kernel 2.6 doesn't need ztdummy as it has a 1000 hz timer built in.  On debian it default to 250hz so you might need to recompile your kernel to make what ever interval is needed by Asterisk (I think the kernel config has options for 100, 250 and 1000 hz).  It has been a while for me, so I'm not certain about the requirement.  I think the newsgroup or the code or the make file refers to it.

Hi Guys,
 
Can anyone tell me how to install ztdummy on the slackware system with kernel 2.6.15, i am not using any digium hardware, i need to install ztdummy on my slackware system which is compiled with kernel 2.6.15.1.
Please suggest the best possible way...................
