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

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
