• voice class uri patterns are case-sensitive and the pattern, user-id and hostname are limited to 32 characters. in context
• A voice class uri can contain at most 10 host ipv4/ipv6/dns entries in total and only one host hostname-pattern entry. in context
• A voice class uri can match on host (hostname pattern, IPv4, IPv6 or DNS), user-id, or pattern (the entire URI string). in context
• When several dial peers match by URI, the longest match wins, and a URI pattern match has no match length so it is the least preferred. in context
• Inbound dial-peer matching by URI works only for SIP (voip session protocol sipv2) and a dial peer can carry only one incoming uri match. in context
• incoming uri via matches against the topmost Via header, which identifies the last hop, and Cisco recommends it when the call traverses multiple SIP hops. in context
• A CUBE voice class uri pattern must be shorter than 32 characters, is case-sensitive, and each voice class uri allows only one pattern or host command. in context
• On CUBE, 'incoming uri via' matches the topmost Via header of an incoming SIP request, which identifies the last hop that forwarded it. in context
• CUBE can select an inbound dial peer by matching parts of the URI sent by the neighbouring SIP entity, for example matching the top Via host IP with a voice class uri and 'incoming uri via'. in context
