RE: [Sipping-emergency] proposed charter, new wg on emergency calling and routing

While validation is important as described by both of you, this should in no way intefere with the processing of a call to an ERC. Feedback should be provided to the end user or IAP if the location information  is out of acceptable parameters (e.g. out of street range, wrong spelling etc.) and also provided to an ERC or ERC service provider as a method to ensure that the erroneous information is corrected BEFORE an emergency call is ever placed. However, the ability for that particular device to place an emergency call should not be restricted by this process (didn't see it anywhere in the proposal but I wanted to make sure that it is stated) - this mirrors the current process of validation here in North America for PSTN originated calls.

Agreed that you COULD change the way the system works now to have a
translation from postal address to dispatch address.  They don't do that
now, but they could.  In that regard, maybe a bad example.  If you were to
propose that the system have a translation, then some kind of spec would
have to be written that said that, which might be a new deliverable.

Misspellings, missing or extra directionals (North, Southwest, ..),
confusion between Main Street and Main Drive, etc. are better examples.
The point is to make sure that the call will be routed correctly,
and responders will be dispatched correctly BEFORE the location is needed to
do so, and the only way we know how to do that is to compare the address
against some kind of master list.
