How to route 911 on remote site without CER

hi,


I would like to know, how does the CM knows that a 911 call comes from a specific remote site and forward the call to the appropriate gateway without using CER. If users on different sites dial 911, how can we redirect the call to the good PSTN ??


thank for you help

This can be accomplished through the use of route patterns, partitions and CSS. CER is not required to route the calls. Since each setup is unique there is no definitive answer to the question, but I will give an example:


PT: HQ-PSTN

PT: Phones

CSS: HQ-CSS (HQ-PSTN, Phones)


Device CSS: HQ-CSS

Line PT: Phones


Gateway CSS: HQ-CSS


Route Pattern: 911 AND 9.911

PT: HQ-PSTN


Using the method of allow on device restrict on the line for PT & CSS, any device with the HQ-CSS PT will route 911 calls out the gateway with the same CSS. This can be setup for each location as desired.


Keep in mind you have to address the gateway configuration ...


Thank you,

Jon
