OpenScape Cordless IP V2, Service Documentation 75
Different OpenScape Cordless IP V2 users from one system may register on both
Geo-separated OSV-nodes or on OpenBranch. In standard customer-scenarios
only one gateway will be used.
For Geo-separated OpenScape Voice:
If the OpenScape Cordless IP V2 INT-DM is directly connected to a Geographi-
cally-node-separated OSV-cluster (Main-Office, no OpenBranch-Proxy involved)
it is necessary to enable Flag "Direct Signaling". Otherwise calls from phones
located on the 2nd node will not be accepted by OpenScape Cordless IP V2. If
this flag is disabled the INT-DM allows only calls from the IP-address where the
OpenScape Cordless IP V2 user is registered to. If this flag is enabled
OpenScape Cordless IP V2 allows calls from any IP-addresses.
So for security-reasons this flag should only be enabled if OpenScape Cordless
IP V2 is used in Geo-separated OSV.
Codec priority (G711a, G711u, G729a, G729b) and RTP framing (20 msec) is
recommended.
