This is more a legal requirement than technical discussion. You should never ever try to delay 911 call for your own good. Thats a huge liability. And what you experienced happened all the time. Here are some suggestions:

1) check your dial plan to make sure it follows best practices
2) educate end user on how to make 911 or 9911 calls
3) turn on CDR to check who made the call
4) inter digit timeout won't help here because 911 route pattern should have urgent priority checked, and as soon as it matches the first three digits - 911, it won't wait for further dialing and the call will go thru
5) in north america, there are strict rules about 911... you do not want to be sued when someone saying there is an intentional delay in establishing a 911 call

  • 工作学习 / 学科技术讨论 / Cisco Call Manager and 911 Call
    我们公司最近把电话升级到CISCO VOIP, 但是开始出现不少误拨的911电话. 我发现CISCO CALL MANAGER 有责任, 因为种种原因, CALL MANAGER 处理拔号非常快, 即时拔出,这样一来 误拔的911来不及HANG UP.

    各位大虾, 有无CALL MANAGER 经验? SOLUTIONS? How to加入拔号延迟?
    • 我不懂call manager,但是我知道,去cisco网站serch一下应该不是什么难事

      看了看,应该是你需要的,像这种问题,cisco网站上都能够查得到,那里绝对是一个资源宝库。
      • This timer is not related. 911 is an explicit match, no delay. If it missed up 9011, you can use 8011 instead.
        • if there is an extension like 911X or overlapping route pattern, and if 911 route pattern is without urgent priority checked, there will still be a T302 inter digit timeout
