[Asterisk-Users] Zapping around

[Aldo Bergamini]

Dear list,

I am trying to learn how to use Zap-things in Asterisk.

While loading Asterisk verbosely I get this error:

[chan_zap.so]Warning, flexibel rate not heavily tested!
 => (Zapata Telephony w/PRI)

Now, modprobing zaptel is ok:

aaberga at epsilon-stargate:~> sudo /sbin/modprobe zaptel
aaberga at epsilon-stargate:~> 

Same with wcfxo, wcfxs

aaberga at epsilon-stargate:~> sudo /sbin/modprobe wcfxo
aaberga at epsilon-stargate:~> sudo /sbin/modprobe wcfxs
aaberga at epsilon-stargate:~> 

although here I do have a first question. The card I am using is a TDM400
with two FXS module, an empty slot and an FXO module.

The wiki mentions a wctdm module that I do not find (modprobing it just
fails). Am I missing something, or can I use the older set of kernel modules?

[info: I did get the 1.0.6 zaptel, libpri and asterisk archives from the
Digium site; I did compile everything under SUSE 9.2, thus with a stock
2.6.8-24-default kernel;
I did use the make linux26 command in the install process of zaptel.
]

Now the card seems to react to my fiddling: the three green leds
corresponding to the installed module positions do turn on as soon as I
type the wcfxo or wcfxs modprobe command.

The zaptel config file is as follows:

************** zaptel.conf **************
the stock file as generated by the compile process, with the addition of
these lines


# edited by aaberga % 12.3.05
loadzone = us
defaultzone = us

fxsks = 1-2
#fxoks = 4

************** zaptel.conf **************


The zapata.conf file is as follows:

************** zapata.conf **************
the stock file as generated by the compile process, with the addition of
these lines


; edited by aaberga % 12.3.05

;signalling = fxs_ks
;context = incoming
;channel => 4

signalling = fxo_ks
context=internal
channel => 1-2

************** zapata.conf **************

I am obviously missing and/or misdoingsomething; can anybody help?

Thanks in advance
Aldo
