[Asterisk-Users] Voicetronix OpenSwitch12 chan_vpb problem

[Jan Henkins]

Hello all,

I hope this is not off-topic, if it is please let me know.

I'm currently playing with an Asterisk at home, in order to get to know
it's ins and outs. Very very impressive indeed. I've got it hooked up to
my home phone line via a Wildcard clone board (Intel modem with Ambient
chipset), and it works like a charm. Zaptel picks up the card as a
generic clone, and works with it without any problems. The versions of
Asterisk I'm playing with ranges from stable 1.0.5 to the latest CVS
versions of asterisk, libpri and zaptel.

I've got a Voicetronix OpenSwitch12 card on loan, and I'm trying to get
it to work with Asterisk. No matter how I try, it seems that I've got a
bit of a lemon. Here's the problem so far, maybe somebody has stumbled
across something similar and knows of a workaround or fix:

The Voicetronix driver (version 2.4.0) compiles perfectly, and Asterisk
links against it nicely too, resulting in the chan_vpb.o being built.
All the test software that comes with the Voicetronix driver sees the
card properly, and I can even use the little test PBX program that comes
with it's troubleshooting toolbox (I forget the name, it's a tiny little
C++ program) to get the card working as a very primitive PBX. In other
words, the card works nicely. Btw, this works perfectly with my wildcard
in place and the zaptel/wcfxo modules loaded, only Asterisk has not been
started.

Over to Asterisk, when I try to initialise this card with chan_vpb, my
computer locks up solidly (with me ending up having to do a hardware
reset). Asterisk starts up beautifully until it reaches chan_vpb, and
then it simply hangs. Here is a short snip of what it looks like when I
start up Asterisk:

Weird... The last line is also present with you use vpbconf to look for
Voicetronix card configuration, the only difference being that the
computer doesn't lock up:

---start---
#/usr/sbin/vpbconf

---end---

Looking in /proc/interrupts shows up both my wildcard clone and the
V12PCI card on different IRQ's, so it seems that there are not any
clashing between the two. The only thing I can think of is that it's
quite an old card (see the date and revision above), which might be an
issue. Has anybody stumbled across something like this? If not, do you
know who I can contact for help? This particular Asterisk installation
is not a production machine at all, merely a "getting-to-know-you"
exercise. However, it would be nice to know wether Voicetronix products
are on the trusted list or not.

Thanks in advance!
