Sangoma Wanpipe

Note: Since AstLinux 1.2.9 Sangoma Wanpipe card support is no longer supplied in the standard AstLinux images.
Use a custom build to enable 'wanpipe' support.

Starting with AstLinux 0.7.6 the utilities wancfg and wancfg_dahdi which configures Sangoma telephony cards for DAHDI, are supported. These utilities define files in the /mnt/kd/wanpipe (aka /etc/wanpipe) directory.

Previous to AstLinux 0.7.6 the utilities wancfg and wancfg_dahdi were not supported. The configuration files must therefore be created manually for older versions of AstLinux.

With AstLinux 1.0.2 the A500 and B700 BRI/Hybrid cards, which work now with DAHDI¹⁾, are supported too. The “wancfg” tool is only for cards used in “data mode” and does NOT work with the B700 card, “wancfg_dahdi” is needed for “voice mode” together with Asterisk.

Remember that AstLinux stores the majority of its configuration files in a different location to where vanilla Asterisk installations store theirs, so use the locations listed below.

/mnt/kd/wanpipe/wanpipe1.conf  (aka /etc/wanpipe/wanpipe1.conf)
  
/mnt/kd/dahdi/system.conf  (aka /etc/dahdi/system.conf)

/mnt/kd/asterisk/chan_dahdi.conf  (aka /etc/asterisk/chan_dahdi.conf)

Here are sample Wanpipe configuration files (for a Sangoma A101u in a Soekris net5501 connecting to a US T1). They will need to be customized to fit your own environment.

/mnt/kd/wanpipe/wanpipe1.conf:
