No.

Describe the solution you'd like

At present, the generation of callee callid uses word64 (base64), and the final length depends on the upstream callid, usually the design of the upstream and downstream systems may have the length of the callid within 64 characters, but after base64 expansion, the downstream system may have to be modified due to risks.

For example, use hash at the end to make the final output of the same length, is this possible?
