When a DPNSS feature is interworked between
a legacy DPNSS PBX network and Cisco CallManager
(and vice-versa), the feature mimics the
implementation as it functions in a DPNSS
network.
However, there may be some differences
between the implementation of DPNSS and
IP features. Check these documents so that
you can anticipate these feature differences. |
