Customer use "Dual SC Networking" solution. SMC2.0 version:V100R003C10SPC100,
all internal VC endpoints register in SC1, and public endpoints communicate with SC2, the topology is:
They created the "always on" conferense in SMC2.0 with the conference ID format: 8xxxx
when they create the search rule as "Any alias"from SC1 to SC2, they even can't call the "always on" conference 8xxxx
when they change the search rule as "Prefix match 1000" from SC1 to SC2, the call also unsuccessfully to public endpoints 1000xxxx@PublicIP
Modify the search rule as below, and call successed.
The Prefix match can be used for digits only, and Regular expression match can be used for any regular espression.
Prefix match: Enter a string of digits. The SMC2.0 searches for matching rules by starting from the first digit.
Regular expression match: Enter a string of regular expression. For example, to search for aliases that start with abc, enter abc(.*).
