Setting Up the SIP Route Pattern for Routing Calls Use this procedure to create SIP Route Pattern with the domain name and associate the same with the previously created SIP trunk. All emergency calls that are routed to the Emergency Provider must match a route pattern. The route pattern directs the call to a Route Group, Route List, and SIP Trunk or PRI gateway that can reach the RedSky server. PRI - RedSky provides the customer an account-specific access number. In this case, the number is the customer ID and the CALLING PARTY is the user reference. It follows traditional RP/RG/RL/GW redundancy. The calling party number must match the RedSky user’s ID. We recommend using SIP Trunks to connect with the RedSky server. For dedicated instances, this is the default method. For customers having an on-premises deployment of Unified Communications Manager on-premises, you must configure the SIP Trunk, Route Group and Route List before creating the route pattern that will be used to reach the RedSky server. If using a SIP trunk, the administrator must use a predefined LUA script to ensure proper customer identification. For Unified CM deployments, you must upload the script and apply it to the SIP Trunk. The LUA script allows for only one parameter, which is the RedskyOrgID. Procedure Step 1 From Cisco Unified CM Administration, choose Call Routing > SIP Route Pattern. Step 2 Click Add New to add the RedSky route pattern. Step 3 From the Pattern Usage drop-down, choose Domain Routing. Step 4 Enter the route string in the IPv4 Pattern or IPv6 Pattern field depending on whether you are deploying the IPv4 or IPv6 address. Step 5 Choose a RedSky SIP trunk in the SIP Trunk/Route List* drop-down. Step 6 (Optional) Click the Edit link to view or change the Trunk Configuration details.
