[chan-capi-users] Problem with AVM C4

[Louis van Dompselaar]

We've been running an asterisk 1.0/chan_capi 0.3 with the AVM C4 since  
2005 and
it has been working fine.  However, we changed telco and the new telco
couldn't talk to that version for some reason.  We didn't get any ring  
or busy tones.

In an attempt to fix it (as the telco couldn't), we installed the  
latest asterisk and
chan_capi (1.4.26 and 1.1.3). That fixed the ring tone issue, but now  
we have lost
outgoing audio to mobile phones.

What we get is:

[Aug 11 08:27:26] ERROR[24554]: chan_capi_utils.c:473  
log_capi_error_message: CAPI error sending DATA_B3_REQ                 
ID=002 #0x0188 LEN=0022
   Controller/PLCI/NCCI            = 0x10102
   Data32                          = 0x84bd39c
   DataLength                      = 0xa0

   Data64                          = 0xd4e4d658940cbfae

on every audio packet.  I've already tried the latest version from  
svn, which doesn't
make a difference, and downgrading to earlier versions, which also  
doesn't
make a difference.

I've also tried the 320 byte packes size in chan_capi.h as was  
suggested elsewhere,
with no effect (and the problem seems to be that the packets are too  
small, anyway).

Anyone seen this before and any suggestion why it should be limited to  
mobile phones?
