Adding a delay of 3 or 4 seconds to 911 route pattern using an MGCP gateway

Unanswered Question
Jan 15th, 2010

Hello,

I am having several users calling 911 in the past few days...we have 2 patterns 911 and 9911, of course we have been getting several calls from 911 about hang ups!....so my thought is to somehow add a delay of 3 to 4 seconds before routing the call to the pstn, I have a ucm 7.1.3, cluster with an mgcp gateway to the pstn. Any help will be greatly appreciated thanks!

I have this problem too.

Hello,

What I end up doing was create a translation 911 to a cti route point to a unity call handler with a recording ....connecting to 911 please wait...then passing the call to 911 to the vg...(the recording its about 3 to 4 secs long) enought for the user to realized that he / she is about to make a 911 call and hopefully hang up....Thanks guys for your help!

Be careful with that. If Unity fails, then the call is going to fail and you have no 911 pattern.

Make sure you have a call foward rull for 911 to another pattern to translate to 911 and go outbound to PSTN.  (similar to how we setup CER)


You can also create a route pattern "911X"   Then adjust your interdigit timeout to say 5 seconds.   CallManager will wait for 5 seconds for the "X" digit.  No digit, it will send 911 to the PSTN.
