Calls to or from non-SIP endpoints on Communication Manager over ISDN trunks are not routed by default through Session Manager and so do not have access to Avaya Breeze® platform Call Intercept services. However, you can administer Communication Manager to route Public Switched Telephone Network (PSTN) ISDN calls through Session Manager for Avaya Breeze® platform processing.

This procedure is necessary only when Call Intercept services are used on calls between stations and ISDN trunks on the same Communication Manager instance.

For detailed instructions for any of the procedures described in this section, see your Communication Manager documentation.
