72 OpenScape Cordless IP V2, Service Documentation
If the OpenScape Cordless IP V2 system has to be connected to a geo-separated
OSV it is recommended to include OpenBranch, which is described below.
OpenScape Cordless IP V2 is connected to OpenScape Voice via
OpenBranch:
In this setup scenario, OpenScape Cordless IP V2 is communicating with
OpenBranch-SIP-address only and OpenBranch-proxy is forwarding all SIP-
messages to OpenScape Voice. To avoid a single-point-of-failure at
OpenBranch-side it is strongly recommended to set up OpenBranch redundantly
(using VRRP).
In case of node-failure in a clustered-OSV OpenBranch will address OpenScape
Cordless IP V2-messages to the remaining OSV-node (doesn’t matter if co-
located or geo-separated OSV is used).
5.3.2 Base Configuration - OSV
OpenScape Cordless IP V2 endpoints have to be configured in the same way in
OSV-configuration as other SIP-users do. OSV does not know anything about the
OpenScape Cordless IP V2 DECT system. All OpenScape Cordless IP V2 users
will register at OSV with the same INT-DM address.
Usage with OpenScape Web client:
If OpenScape Cordless IP V2 users are used with OpenScape web client, the
OpenScape Cordless IP V2 users feature-profile should be set to CSTA =
Normal.
Only Limited feature-set using web client is supported.
