[cisco-voip] Hosted E911 over SIP

[Norton, Mike]

Yes, it is interesting that you bring that up. Do you have any info/links on that? A potential Lync pilot project on the horizon is actually part of the reason I'm looking for an E911 solution. I thought it just had to be to a SIP trunk, not necessarily to an off-premise provider. I.e., a SIP trunk to an on-premise CER-like product would still work... at least, that was my thinking.

Just for FYI, with Microsoft Lync, hosted E911 service is the only supported solution.  Thought that would be interesting to bring up.

Yeah, I guess it would be a little less "dirty" feeling in cases where the whole phone is already across the Internet anyway. Hadn't really thought of that scenario.

My inclination is to look for a product that does it like CER does, but all the vendors' material that I've looked at makes it seem like hosted is the way to go, even though most of them do offer something for both methods. Thanks for the feedback; helps to confirm my thinking isn't way out to lunch.

I'm there too......   But i Know 911 enable does have an on site appliance so we can do the same as CER.

But where I think the "dirty feeling SIP" does come into place is with lots of telecommuters.  I know of a very large company that has hundreds if not thousands of telecommuters that have soft and hard phones at home.  They (the company) feels that they should provide 911 service to there telecommuters.  Since each telecommuter does not have a VGW they use a E911 SIP provider to route the call to the correct PSAP.  Now if you don't have any VGWs in a city that a telecommuter might be in.... I can see it.

But for a normal environment...... I do understand the "dirty" feeling.

Very well said Mike and I for one totally agree with your "Dirty and  just wrong " of 911 traffic over the Net.
Most customer's I have met also say: it just sounds wrong no matter how much $$$ we save. these types of mission critical calls should be forced out over conventional media.

Does anyone use any of those "hosted" E911 services (e.g. 911 Enable, Red Sky, etc.) where you send them the 911 calls over the Internet using SIP?

In my mind, sending calls over the Internet feels dirty and wrong, and sending emergency calls that way feels just plain stupid. How do you deal with lack of QoS and having basically no control over availability or capacity? For regular calls, I could understand just living with it (in some applications) - but for 911? Seriously?

Is hosted E911 one of those services that looks pretty in a marketing PDF but nobody actually uses in real life?
