Thank you Joshua. I will read both links you provided.
As mentioned in another response. If what our customer requires doesn’t fit well with Asterisk development, we believe we can do this work with Kamailio front ending the calls. Something customer is already requiring us to do for high availability requirements (911 call center). Asterisk would be far cleaner since there would be no timing issues of call information from 2 boxes. Dan From: asterisk-users <asterisk-users-boun...@lists.digium.com> On Behalf Of Joshua C.

What I have understand, E911 geo information is sent “out of band” when 911 is called. So the question is, is you operating a 911 call centre – then you should have this information at hand already how to access this information. Or are it the opposite, you want to send geocoded information about SIP handset location to a E911 service when 911 is called? (that you want to embed in the outgoing body when 911 is called)? I think gaining access to these types of E911 API’s requires you being a SIP operator – and if you are a SIP operator with a number plan already, you should already have access to these types of API from the beginning and how to use them. There are specifications for conveying location information dynamically in the SIP INVITE to an upstream provider, which uses pidf+xml alongside SDP in the INVITE. This allows you to provide the address, floor, room, longitude/latitude dynamically with the call. You can see what it looks like on the Bandwidth site[1]. It is a standard though, not specific to them. [1] https://support.bandwidth.com/hc/en-us/articles/360006080074-E911-Dynamic-Location-Routing-integration-and-testing-guide -- Joshua C.
