On what basis would a proxy/B2BUA/ALG decide what location to add? I use the same proxy (in my office) from the same UA (on my laptop) from many different locations. > But besides all of this: we've got to get the PSAPs capable of > reliably using the location provided in the call.

I think that is easily refutable: compare of the number of PSAPs and implementations intended for use in them against the number of telephony providers, pbxs, user agents and implementations intended for such use. There are very very few of the former, and they are very highly motivated because they are providing the emergency services; it's the latter that will take the greater time and effort. -- Scott Lawrence tel:+1-781-938-5306;ext=162 or sip:[EMAIL PROTECTED] sipXecs project coordinator - SIPfoundry http://www.sipfoundry.org/sipXecs Chief Technology Officer - Pingtel Corp. http://www.pingtel.com/ _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
