 /* DESC: This script implements an audio voice dispatcher /* DESC: This script implements an audio voice dispatcher
- * The first audio Interface (line-in/out) is used for the GSM-Call audio. 
- * - Dialing os controlled via digital in 1 (in1) 
- *   If it is set high (1), the predefined nummer is called.  
- *   Must be set to high (1) to acknowledge incomming calls. 
- *   Any call will be terminated when it goes low (0). 
- * - Incomming calls are signaled at digital out 1 (out1).  
- *   It's set to high (1) when call is incomming and statys high during call. 
- *   It will go to low (0) when the call is ended.
