asterisk users - Nov 2005 - Sipura doesn't get caller id and hangup with Siemens Combiset

Hi,

I'm trying to setup Sipura to work with  Siemens Combiset 1009 on PSTN line 
(GSM gateway - produced for germany)..

I have two problems:
- Sipura doesn't detect Caller ID
- Sipura doesn't detect hangup condition....

I have 3.1.7(GWg) firmware on Sipura and Asterisk 1.0.9...

Anyone has settings for German PSTN lines or any other similar that should 
work ? Any other advice or help ?

Thanks in advance,

regards,

Rob.
