spool 为 /tmp/media/spool/asterisk
录音存储在 /tmp/media/spool/asterisk/monitor
tmpfs 根据内存不一样大小不一样 - 小的可能只有 30MB 左右 free 内存

⚠️

wg 系列没有 app_stack
- 基于 Debian 8, Linux 4.19.81, asterisk 1.8.20

rtg - 路由分组
一个路由规则会基于目标生成 N 个 context - rtg-test-1
每个目标 include 一个
sounds - 只有部分 sounds 可用于测试
- agent-pass.gsm
- auth-incorrect.gsm
- auth-thankyou.gsm
- vm-goodbye.gsm
