Hello,
I am unable to leave voice mail for users. When I call a voice box I always get the message that I have to give the
number of the voice box first.
My scenario looks like this:
I have a Alcatel 4400 telephone System with four ISDN ports where a Ferrari OfficeMaster Gateway is connected.
The "protocol" at the ISDN Ports are "ISDN alle Länder". There is no QSIG defined. There is a four digits range defined for the UM functions.
At the Gateway there are inbound Rules defined with the Exchange System as the SIP-target.
At the Exchange Server "UM Dial Plan" there is "telephone Extension" as URI type defined.
When I call from external I see the external Number and the target Number like "6814", which is the Voice Extension for my mailbox, at the Gateway Monitor. I get routet to the Exchange Server and then i get asked for the number to call.
When I test the UM funtionality with the following command: "Test-ExchangeUMCallFlow -Mode Gateway -VoIPSecurity Unsecured -NextHop exch001 -Diversion 6814"
I get the message that the diagnostic test completed successfully and the note "If callers are unable to leave voice mail for the user, the issue may lie in the components (such as PBX/IP-PBX/SIP-PSTN gateways) and path preceeding the NextHop."
Where is the fault? Do i have to configure QSIG?
