Advanced Service Interworking
DPNSS Networks Containing PBXs from More than One Manufacturer
You can combine some options that are described in preceding sections. By selecting BOTH in the
Message Waiting NSI option , Ericsson, Mitel, Nortel, and Siemens (GPT) PBXs will get covered.
Contact Support for further advice.
ISDX Voice Messaging Systems
Siemens implemented proprietary extensions to DPNSS Diversion to achieve better integration with
their voice messaging servers (VMSs). You can configure the Cisco VG30D Voice Gateway to attempt
to interwork these extensions with the QSIG Call Forwarding service. However, in some cases,
interworking is partial.
In iSDX/Realitis networks where a single VMS, ensure the Cisco VG30D Voice Gateway is configured
with the SPIDG address (the Logical Extension Identifier for the VMS hunt group - sometimes called
the RFD address). This is unnecessary in multiple VMS networks, where the PBXs assert the required
number explicitly in their RFD signalling. ISDX VMS parameters get set up on the
DPNSS Advanced
page.
Cisco VG30D Voice Gateway units have further advanced configuration options. Your support
organisation may direct you to use these options to resolve specific VMS interworking problems. The
default configuration settings remain correct for most networks.
Name Mapping
Cisco VG30D Voice Gateway units support both the Q.931 display element to transfer name information
(in either direction) and the QSIG Name Identification service options.
The most prevalent use of the display element option is by media gateway (DE30+) cards that are
attached to the Cisco Unified Communications Manager, supporting Q.931 protocol (not QSIG).
