Hi

I have an asterisk box with digium hardware connected to a Siemens EWSD
version 15 using a crossed E1 cable. The asterisk is serving as a h323
media gateway.

When i start asterisk, the Siemens gives me this alarm:

There are no warnings or errors on the asterisk side. The Siemens will
not route calls through this E1 while this alarm exist.

I have found a workaround: i place a call using asterisk through this
E1, the call succeeds and the Siemens clears the alarm.

Everything works wonders for a while. Then, the Siemens starts the same
alarm and i have to place a call manually once again, and again... you
get the picture :(

The Siemens guy tells me that this is a problem with the D channel. I
tried to change the timing for this cirtuit, in zaptel.conf. No positive
results.

Configuration files follows:

loadzone = us
defaultzone=us
span=1,0,0,ccs,hdb3,crc4
bchan=1-15
dchan=16
bchan=17-31
span=2,0,0,ccs,hdb3,crc4

Every idea is welcomed.
