currently I have a problem with my QSIG ECMA CUCM <-> siemens connection.
PSTN E1 PRI<->H323<->CUCM<->MGCP QSIG ECMA E1 PRI<->SIEMENS
the siemens is not delievering a disconnect code, instead it delivers a progress message with the following q931 debug:
Jun 16 15:38:46.460: ISDN Se0/1/1:15 Q931: RX <- PROGRESS pd = 8 callref = 0xBC34
Cause i = 0x8091 - User busy
disc-pi-off is for sure not the problem, because I tried all possible configurations. The CUCM service parameter does now state the following:
Convert Progress to Disconnect for User Side PRI EURO: This parameter determines whether to convert a Progress request that contains a Call Clearing cause value to a Disconnect message. Valid values specify True (convert the Progress request to a Disconnect message) or False (do not convert the Progress request). This parameter is only applicable to the USER side of a PRI EURO interface during the call establishment phase.
But this seems not to work, is this because I have a QISG. Does this paramter need a CUCM restart? I have alredy done a mgcp reset (no mgcp/mgcp). Has anyone a clue, what else could help? The problem is, that the caller hers ringback all the time. Would it be possible to play busy back instead of ringback in that case?
Currently I'm also not sure if the Siemens could be reconfigured so that it sends a disconnect.
any idea is very much appreciated
