• A caller reaches a destination only if the destination's partition is in the caller's calling search space; otherwise the call is rejected, or a translation pattern is ignored. in context
• On an IP phone that has both a line CSS and a device CSS, the line CSS takes precedence over the device CSS. in context
• Any calling device can reach a dial plan entry left in the <None> partition, and Cisco recommends not leaving dial plan entries there. in context
• A route pattern, directory number or translation pattern is placed in a partition by choosing that partition when it is configured. in context
• For an IP phone on Unified CM 11.0, where both device and line carry a CSS, the line CSS takes precedence over the device CSS. in context
• Any device making a call can reach any Unified CM dial plan entry left in the <None> partition, regardless of its calling search space. in context
• Cisco recommends not leaving Unified CM dial plan entries in the <None> partition, to avoid unexpected results. in context
• If the called number matches a pattern in a partition within the caller's CSS, the call is placed or, if the match is a translation pattern, the translation pattern is executed. in context
• On an IP phone that has both a line CSS and a device CSS, Cisco states that the line CSS takes precedence over the device CSS. in context
• Directory numbers, route patterns and translation patterns can each belong to a partition, and a calling search space is an ordered list of partitions that a calling device searches when placing a call. in context
