Hello,

hm, I still can't find a reproducable way for setting up FS with sangoma
A101. I comiled wanpipe with Compilation mode 3 (TDM Voice (Zaptel) +
WAN Protocol Support).

My last way leds to a seg fault (GD-Backtrace):

Program terminated with signal 11, Segmentation fault.

I use wanpipe-3.2.5, latest FS trunk and zaptel 1.4.5 (it seems FS need
zaptel for E1 access).

my openzap.conf is:
[span zt]
trunk_type => e1
b-channel => 1-15,17-31
d-channel=> 16

my /etc/wanpipe/wanpipe1.conf is:

strange here is that zap_zt tries to open a 31st channel ...

As soon as I call 0XXXX FS crashes with seg fault. Nevertheless I flying
blind around, hoping to find the right setup.
