Biasanya, kalau kita menginstall Elastix dengan card analog terpasang sejak awal, secara otomatis system akan mendeteksi keberadaan card dan sekaligus menginstall driver yang diperlukan. Tapi ada kalanya (entah kenapa) card analog tidak terdeteksi. Biasanya, ketika kita menjalankan perintah\u00a0dahdi_genconf -v<\/strong> akan menunjukkan seperti ini:<\/p>\n

[root@ippbx ~]# dahdi_genconf -v<\/em>
\nDefault parameters from \/etc\/dahdi\/genconf_parameters<\/em>
\nEmpty configuration — no spans<\/em>
\nGenerating \/etc\/dahdi\/assigned-spans.conf<\/em>

Problem di atas biasanya terjadi karena kita belum memiliki module\u00a0opvxa1200.ko<\/strong> (untuk card analog) atau\u00a0opvxg4xx.ko\u00a0<\/strong>(untuk card gsm). Untuk mengatasi problem tersebut, yang perlu dilakukan adalah sebagai berikut (pada contoh ini, saya mengalami problem loading driver untuk kartu OpenVox A400p 2 FXS & 2 FXO) :<\/p>\n

1. Jalankan perintah\u00a0lspci -v<\/strong> dan pastikan memiliki output seperti:<\/p>\n

03:00.0 Communication controller: Tiger Jet Network Inc. Tiger3XX Modem\/ISDN interface<\/em>
\n Subsystem: OpenVox Communication Co. Ltd. OpenVox A400P 4-port analog card<\/em>
\n Flags: bus master, medium devsel, latency 32, IRQ 58<\/em>
\n I\/O ports at d000 [size=256]<\/em>
\n Memory at e2100000 (32-bit, non-prefetchable) [size=4K]<\/em>
\n Capabilities: [40] Power Management version 2<\/em>
\n Kernel driver in use: wctdm<\/em>
\n Kernel modules: wctdm, wcopenpci, hisax<\/em><\/p><\/blockquote>\n

2. Jalankan perintah :\u00a0dahdi_hardware\u00a0<\/strong> yang harusnya memiliki output:<\/p>\n

pci:0000:03:00.0 wctdm+ e159:0001 Wildcard TDM400P REV E\/F<\/em><\/p><\/blockquote>\n

Jika setelah kata\u00a0wctdmi\u00a0<\/em>memiliki tanda minus (‘”-“) misal seperti:<\/p>\n

pci:0000:03:00.0 wctdm- e159:0001 Wildcard TDM400P REV E\/F<\/p><\/blockquote>\n

hal tersebut disebabkan mod\u00a0wctdm\u00a0<\/em>belum diload.<\/strong><\/em>\u00a0<\/strong>Jalankan perintah:\u00a0modprobe wctdm<\/strong> dan kembali lihat output\u00a0dahdi_hardware.\u00a0<\/strong><\/p>\n

3. Jalankan perintah modprobe opvxa1200 debug=1<\/b>, lalu generate config dengan perintah:\u00a0dahdi_genconf -v<\/strong>. Jika berhasil seharusnya akan muncul output seperti :<\/p>\n

[root@ippbx ~]# dahdi_cfg -v<\/em>
\nDAHDI Tools Version – 2.9.2<\/em><\/p>\n

DAHDI Version: 2.9.2<\/em>

\nSetting echocan for channel 2 to oslec<\/em>
\nSetting echocan for channel 3 to oslec<\/em>
\nSetting echocan for channel 4 to oslec<\/em><\/p><\/blockquote>\n
