These routes include routes for private digit dial plans, routes to gateways, and telephony-style routing between SIP domains. Multiple lists can reuse the same routes in a route list.

•assign class of service (COS)

COS is basically used to block particular types of calls, such as international dialing or long-distance dialing. For example, telephones in an office lobby can be restricted to local and emergency calls only in a domain.

Figure 5, “Relationship between Telephony routing stages,” shows the relationship between the telephony routing stages provided by the SIP Application Module. If the COS value of the subscriber and subdomain route do not match, then the SIP Application Module checks the parent for routes with the same or higher COS value.
