Re: [asterisk-biz] Simulating 911 ANI/ALI

Hi Dave

It's not that simple. All I need for now is to prove that the Asterisk manager interface can show the data messages that comes through the SIP trunk from the provider's end. Since the provider is not in the picture, for now I only need to somehow simulate this so that the customer could see it for themselves by perhaps sending those information from another say... asterisk to behave like a provider. As far as the provider is concerned, they will only sell their services and nothing more. Hope you can see what I mean.

Si,
if you can't make double the cost+ of the development on the application, drop it or pass it off to the provider and take a commission. 
you have to make the investment with the provider (or some deal where he/she will do the prototype for free based on you and him getting the final deal) to get the prototype done since you can not do it yourself.  in any case, you will, most likely, have to put the provider and the customer together for the project to be successful.
get a non-compete, non-circumvent, or agency contract between and with both you and the customer and the provider.  meaning a contract between;  a) you and the customer, and b) you and the provider....
specifically, that the customer is yours and the provider can not circumvent you on this or future deals.

Actually I am biding for the project and I am in between the provider and the customer. The customer wants me to do a demonstration first as a proof of concept but the data will be subject to the final confirmation by the provider. Until then I won't be able to talk to the provider directly as it is masked by the customer. Any suggestions?

... I plan to use Asterisk as the front end to  connect to a provider who will connect via SIP trunk and pass all 911 calling  informations like... 1. ANI (Automatic Numbering Information) 2. ALI (Automatic Location Information) a. Caller no b. Building name / caller name c. Address d. Latitude and Longitude of the caller address  3. Incident Information a. Incident code b. Incident Description. c. might have other information as well.  Then I wish to pass these through the manager interface where it can be  collected and processed into a database server to display it on a console...  perhaps like a crm pop-up.     

  You will need to contact the provider that will send these details via SIP  and ask of the standard they will be following.  I'm not aware of any  single standard that will address the information you are expecting.  You might want to review:  http://www.voip-info.org/wiki/view/Asterisk+-+documentation+of+application+commands#SIPcommands  http://www.voip-info.org/wiki/index.php?page=Asterisk+func+sip_header Synopsis - Gets the specified SIP header  http://www.voip-info.org/wiki/view/Asterisk+cmd+SIPGetHeader With this app, you can pick any header from an incoming invite and stuff it into a channel variable. It is a generic way of supporting any  header a vendor or service provider may add that you want to use in your  dialplan.  In the US, the PSAP (Public Safety Answering Provider/Point) is given the  ANI (an identification number, normally a billing phone number) with the  telephone call and they must then use a seperate communications circuit connecting them to a database provider to query for the information needed  to dispatch the call.  Please let me know what standard or spec they are using in their SIP  calls. As a CLEC and VoIP service provider myself, I'm always interested  in learning of new developments in this area.     -Eric Osterberg     Sound Choice Communications LLC      Minnesota, US  _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com--  asterisk-biz mailing list To UNSUBSCRIBE or update options visit:    http://lists.digium.com/mailman/listinfo/asterisk-biz
