[Serusers] ser + Vegastream vega 50 BRI : Handling incoming calls

Hi, can anyone help me with this Problem: I am running a Vega 50BRI Gateway with ser 0.8.14. Outgoing Calls are handled correctly. But when I try to make a call from PSTN to the Gateway, I get this strange error: --------------------------------------------- SIP Messages: Vega50----INVITE---->SER: SER----INVITE---->UAC Vega50<----TRYING----SER Vega50----CANCEL---->SER ---------------------------------------------- The Vega 50 Event log show this: LOG: 01/01/1999 00:05:09.852 ISDN (I)R01C01 incoming call ref=[f1000020] srce=TEL:0031523338540,DISP:0031523338540 AMT,NAMEC:0031523338540 AMT [0] LOG: 01/01/1999 00:05:19.857 ROUTER (I)R0bC00 FINDROUTE profile:2(ISDN_TO_LAN) plan:1 call ref=[f1000020] <-- ISDN [1,1] dest=TEL:1004 --> SIP [1,1] dest=TEL:Oliver LOG: 01/01/1999 00:05:19.967 ISDN (I)R04C01 disconnect 81 call ref=[f1000020] LOG: 01/01/1999 00:05:19.972 SIP (I)R04C11 disconnect(disc req) 81 call ref=[f1000020] --------------------------------------------- My Vega 50 Dial Plan for incoming calls: [planner.profile.2] enable=1 name=ISDN_TO_LAN [planner.profile.2.plan.1] cost=0 dest=IF:99,TEL:Oliver group=0 name=From_ISDN srce=IF:01,TEL:<.*> ----------------------------------------------- The result is that, after the PSTN caller gets disconnected after ca. 8 seconds, the SIP-UAC starts ringing. What did I wrong ??????
