The configuration process of an SBC should always begin with running a wizard. However, the wizard only needs to be run for the very first configuration.
Lync Wizard Task
Media Configuration for TCP/RTP
Use the following diagram and the steps to configure the Media and TLS profile for the ISDN to TLS SIP Server call.
TLS Media Configuration Flow
Media Configuration Steps
1. Ensure there is a media profile for your preferred codec
2. Review the Crypto Profile
3. Verify the Media list for Media and Crypto Profiles
4. Verify the TLS Profile
In the SIP Server Table:
5. Add a SIP Server Host for the FE/SBA FQDN and set the TLS profile
6. Set the SIP Options and the (7) TLS Reuse Parameters
In the destination Signaling Group:
8. Set the Media List entry
9. Set the Federated FE/SBA FQDN and port:5067/protocol:TLS/TLS Profile

Use the diagram and steps to configure a call route from ISDN to the TLS SIP Server.
ISDN to Lync Call Routing Configuration Flow
Call Configuration Steps
1. Create a translation table/entry to perform any necessary number translations
2. Create a Call Route entry. Configure the translation table name and Egress SG configured from the previous page; (3) enable transcoding and set the appropriate media list entry .
In the Ingress SG:
4. Verify/Set the Call Route Table and (5) incoming ISDN port
