Configure Unified CM for Webex Calling
You may required an integration with Unified CM if Webex Calling-enabled locations are added to an existing deployment where Unified CM is the on-premises call control solution and if you require direct dialing between phones registered to Unified CM and phones in Webex Calling locations.
Configure SIP Trunk Security Profile for Trunk to Local Gateway
In cases where Local Gateway and PSTN gateway reside on the same device, Unified CM must be enabled to differentiate between
two different traffic types (calls from Webex and from the PSTN) that are originating from the same device and apply differentiated
class for service to these call types. This differentiated call treatment is achieved by provisioning two trunks between Unified
CM and the combined local gateway and PSTN gateway device which requires different SIP listening ports for the two trunks.
Create a dedicated SIP Trunk Security Profile for the Local Gateway trunk with the following settings:
Setting
Value
Name
Unique Name, such as Webex
Description
Meaningful description, such as Webex SIP Trunk Security Profile
Incoming Port
Needs to match port used in local gateway config for traffic to/from Webex: 5065

The last partition onNetRemote is only used in a multi-cluster environment where routing information is exchanged between
Unified CM clusters using Intercluster Lookup Service (ILS) or Global Dialplan Replication (GDPR).

What to do next
Make sure to add this partition to all calling search spaces that should have access to Webex destinations. You must add this
partition specifically to the calling search space that is used as the inbound calling search space on PSTN trunks, so that
calls from the PSTN to Webex can be routed.
