I had the same problem. To fix this, I needed the following patch against
chan_visdn.c:
@@ -2155,6 +2155,7 @@
static const struct ast_channel_tech visdn_tech = {
.type = VISDN_CHAN_TYPE,
.description = VISDN_DESCRIPTION,
+ .capabilities = AST_FORMAT_ALAW,
.requester = visdn_request,
.call = visdn_call,
.hangup = visdn_hangup,
After this, asterisk didn't complain anymore about codecs, but just crashed.
gdb showed why (part of the original patch):

i.e. first *name and *number are set to NULL, then data is copied...
After (just for fun) changing these to strdup's I got the ISDN PBX to
ring the phones, but I didn't get a valid connenction, the PBX gave
up after a few seconds, and so did I, as I wouldn't know where to look
for this problem.
