182 Queued
The called party is temporarily unavailable but the server has decided to queue the call rather than reject it. The call will be attempted when the callee becomes available.
이 코드를 보게 되는 경우
In call center or queuing scenarios where the callee is busy but the system holds the call in a queue.
해결 방법
Wait for the call to be dequeued. If queuing is not desired, configure the server to reject calls instead of queuing them.
