Dialing 911 or 411 RRS feed

  • Question

  • Our telco supports our using 10 digit dialing for all numbers including local numbers and others in our local exchange. This has made our setup very simple for dialing. However one thing I have not figured out is how to setup dialing for numbers like 411 and 911 between OCS and our AudioCodes media gateway. Is there a document that outlines how to handle these 3 digit numbers that need to route to the PSTN? Our internal extensions are all 4 digits.


    Thank you in advance.

  • What specifically isn't working with 3-digit numbers in your environment? There really isn't much to getting it working so is it related to your OCS configuration or the gateway config?


    It's typically recommended to use separate Voice Policies and Phone Usage for 911 and all other three digit codes (211, through 811) so that you can include 911 in ALL usages but may block the other codes for certain users if you don't want everyone racking up 411 charges.


    With that in mind, and assuming you are using the prefix '9' to dial out, the normalization patterns and translations would look like:


    Local 911




    All 3-digit service codes
