Hello people, this is my first mail to this list. I’m new to asterisk
and trying to set up an IVR. So far my dialplan works nice connecting
with softphones, but I’m having problems to detect hangups on the analog
Here are the details:

-Clone pc with Ubuntu server 10.04 64 bits
-Asterisk 1.6
-Openvox A400P, lspci -v says:
01:00.0 Network controller: Tiger Jet Network Inc. Tiger3XX Modem/ISDN
Subsystem: Device b100:0001
Flags: bus master, medium devsel, latency 32, IRQ 21
I/O ports at c800 [size=256]
Memory at ff0ff000 (32-bit, non-prefetchable) [size=4K]
Capabilities: [40] Power Management version 2
Kernel driver in use: wctdm
Kernel modules: wctdm, wcopenpci, hisax, netjet

And this is the scheme:

PSTN <-----> Analog Panasonic PBX <-----> Asterisk

The problem as you already may know, is the busy/hangup tone generated
by the Panasonic PBX, connecting the asterisk boc directly to the pstn
works fine.
The Panasonic model is KX-TA616, as far as I understand, the manual[0]
says that it can detect Polarity reversion, but not generate it.
I recorded the hangup sound (using Record()), converted and opened in
audacity: it’s 260ms tone, 250ms
So I configured:

But sill can’t detect the hangup.

The tone can be downloaded here
And the dahdi configuration is here:

Let me know if you need any other details on the setup.

Thank you very much in advance.


PS: please excuse my bad english.
