Hi, List!
I got it! Now can I call mobile phones with Asterisk. If someone is interested, the problem was in the Asterisk-configuration (from HowTo).
To use in extensions.conf is:
[btsctrl] exten => _02X.,1,GotoIf($[${CALLERID(name)} != ""]?4) exten => _02X.,2,Set(CALLIDORIG=${CALLERID(num)}) exten => _02X.,3,Set(CALLERID(num)=02${CALLIDORIG}) exten => _02X.,4,Dial(LCR/GSM/${EXTEN:2},120)
So can I define a prefix (02) for mobiles and forward the calls to LCR.
Maybe help someone other having my problem. I suggest Andreas Everberg to update his HowTo...
And now the next problem: calling a VoIP-phone from mobile phone... :) I'll get it, too!
Bye
