1.2. STM Deployment Considerations
The STM has been made to protect the SIP based PBX/Gateway Servers against SIP based
network threats and anomalies. Thus it is recommended to deploy the STM along with the
PBX/Gateway deployment as given in the following scenarios based on what is applicable in
the user’s setup.
Deployment Scenario 1
Note:
Some of the PBX/Gateway devices may have an exclusive LAN/Mgmt Interface for device
management purpose other than the Data Interface (also referred as WAN/Public Interface).
In such cases LAN port of the STM should be connected to the Data Interface (WAN/Public
Interface).
Deployment Scenario 2
In the case of PBX deployed in the LAN Setup, the following setup is recommended as it
would help to protect against the threats from both Internal Network as well as the threats
from the Public Cloud penetrated the Non SIP aware Corporate Firewall.
