[asterisk-users] OSLEC and zaptel-1.4.5.1

[Alan Lord]

Hi all,

After reading great things about the OSLEC Echo Canceller 
(http://www.rowetel.com/ucasterisk/oslec) and seeing the reactions of 
people who have tried it on a recent Trixbox thread 
(http://www.trixbox.org/forums/trixbox-forums/open-discussion/need-people-echo-problems), 
it sounds like it is the "bees knees" for sorting out echo problems with 
cards like the x100p.

Has anyone managed to get oslec to work with recent zaptel and kernel 
(I'm running 2.6.23)?

Lots of information below. Comments/suggestions welcome.

Having followed the instructions on the oslec site, and ensuring the 
patch for zaptel takes O.K (I manually installed the patch into the 
zaptel source tree just to make sure). I can build the oslec module, and 
build a patched zaptel-1.4.5.1-oslec without any compilation issues.

However when I reload the system during boot-up dmesg tells me:

Zapata Telephony Interface Registered on major 196
Zaptel Version: 1.4.5.1
Zaptel Echo Canceller: MG2
Zaptap registered 'sample' char driver on major 33 (This means the patch 
went in O.K.)
ACPI: PCI Interrupt 0000:00:08.0[A] -> GSI 17 (level, low) -> IRQ 22
wcfxo: DAA mode is 'FCC'
Found a Wildcard FXO: Wildcard X100P

Notice the choice of echo canceller....

If I look at what modules are installed:

# lsmod
Module                  Size  Used by
zttranscode             6280  0
ztdummy                 3432  0
wcfxo                   9760  0
zaptel                200120  7 zttranscode,ztdummy,wcfxo
crc_ccitt               1792  1 zaptel

No oslec :-(
