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 line. 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 interface 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: busydetect=yes busycount=3 busypattern=260,250 But sill can't detect the hangup. The tone can be downloaded here http://cringer.3kh.net/web/hangup-tone.wav And the dahdi configuration is here: http://cringer.3kh.net/web/chan_dahdi.conf http://cringer.3kh.net/web/dahdi-channels.conf Let me know if you need any other details on the setup. Thank you very much in advance. [0] http://smarthomeuae.com/new3/product.php?productid=218&pcategory=16001 PS: please excuse my bad english. -- Ariel Wainer Contenta Mobile
