OpenScape 4000 interworking with OS SBC and MS Teams supports two setups with:
- Three SIP trunks (Native SIP trunks located on the SoftGate/STMIX/STMIY) connected
to
SBC via Clustered Mode.
- Only one SIP trunk.
To configure the OpenScape 4000 routing, see
Section 14.3.2 for
the general configuration steps.
