I Have studied Line CSS has more precedence than Device CSS, Line CSS is for blocking pattern where as Device CSS can be used for Routing pattern.
Line CSS has blocked partitions
Device CSS has partition
If IP phone contain both device and Line CSS , it can not be able to call international and LD as line CSS is blocking those partitions.
Please correct me if I am wrong?
Yes, as per your example, the IP Phone won't be able to dial LD and International Numbers because both Line and Device CSS contains LD and International Partition. The Phone is able to dial Local Numbers only.
