911 from remote VoIP Office

[TimAbney]

We are using Intrado to manage our 911 services and they are having a hard time helping us get this remote office set up.

We will have a new clinic 100 miles away using VoIP phones registered back to our CS1K. We have a local number but for some reason we are unable to get to the correct PSAP when sending that number as our E911 information.

Anyone else out there with this situation?

Yes we did this with our remote site 45 miles away (that is all VOIP). You have to build an ERL zone table and then assign the new ERL in each phone build. I am not familiar with Intrado but it looks like they are a provider when you don't have any local trunks? Typically what you do is route out the remote site's local trunk first and if it is not usable you have a COT/1FB that you would route out as last resort (costs about $30/month). You should have at minimum a local trunk in case your trunks are ever down at the main site OR if you ever have a WAN issue and the site is on its own ...
911 can be a pain in this regard - making sure remote sites go out local trunk first/COT for failover. I think your issue is that you may have to define a different 'local' number and use that as your broadcast in your ERL table.

It could also be that your local trunk carrier has the wrong PSAP - our local carrier had the wrong county for our local trunk so when the remote site made a call it would still reach our main site even though our ERL table and CLID config was correct. You should probably call your lcoal provider first if you think all the configuration is correct on the PBX to have them verify what PSAP they have for remote site 'local' calls.
Final Note:
Example - our main default was ERL 0 of course which broadcasts a main number then we have ERL 1 which is also our main site for our DIDs then we have ERL 2 which is our remote site that broadcasts a different 'main' number. You also want to be sure your CLID assignment is correct for each phone build the 1 and the 4 below are the CLID tables that each key uses.

Example:

Main site
ERL 0

KEY 0 1000 1

Remote site
ERL 2

KEY 0 2000 4

Best of luck getting it setup properly.

Thanks Tman,

We do not have any equipment onsite other than the router and layer 2 switch and the telephones. So with no local trunk to route calls from we are limited to using ERLs or CLID entries to send a local number which we hoped would route to the local PSAP from our pbx.

We will have a local fax line they will be able to use for 911 calls but we do not want to limit them from using their VoIP phones.

This is the very reason they have Branch Office so you can route the 911 call out a local trunk
