911 on SIP
« on: June 11, 2020, 09:36:47 AM »
We currently have an issue with our current system and 911 and looking to see if SIP will help solve it.  Here is the setup.

We have a 3300 with 5 locations.  Most of our main numbers (we have a few) come into site 1 and some others go to other sites. The issue started when 911 was called from site one bldg 2 and the first responders  came to bldg 1.   Site 1 actually has two buildings with two addresses.  the entire org has two PRI's, one at site 1 and one at site 2.  We have no setup that will allow us to show 911 calls the different locations without a big cost.  There are some options that we can go down but the cost is ridiculous.  Will putting in SIP trucks make this any easier for us to tackle the 911 issue?  We are going to add them if this helps.  Any comments or suggestions are welcome.  Thanks guys!

Network Zones and location based numbers should take care of this for the most part. Might have some e911 issues where a single site might require multiple zone

Yes, here's why. The PRI's are on the regulated side of the house and carriers will not send a CESID from the system but rather the physical location of the copper trunk (PRI) when 911 is dialed. SIP Trunks have wider flexibility and can send CESID's for multiple building addresses.  You will need to register the E-911 with the carrier which should be a relatively simple process. You will need a properly configured SIP gateway as well.

I look at the OP as a call routing issue. Yes sip might help, some PRI carriers can handle multiple FX locations for this. Even with Sip, there is programming required
