[cisco-voip] ETSI supplementary service problem

[Teodor Georgiev]

        Hi,

 I have the implemented the following scheme:


 Siemens HiComm PBX <--- E1 PRI --->  Cisco AS 5350 <--- E1 PRI ---> PSTN 
Telecom
  

 The ISDN "switch-type" is net5 (aka ETSI).

 The Telco is supposed to send us AOC charging units. That has to be sent to
 the Siemens PBX which takes care of charging / billing every call.
 
 The problem is that Cisco does *not* always forward the AOC message to the 
PBX.

Here is an example (debug isdn q931) message, where Telco sends to Cisco the 
AOC message, but it is not forwarded.

Feb 25 10:48:44.917: ISDN Se3/0:15 Q931: RX <- FACILITY pd = 8  callref = 
0x8E7E
        Facility i = 0x91A113020227B7020122300AA105300302010B820100

 
Any ideas / tricks ???
