Re: [Ecrit] emergency call termination

[Marc Linsner <mlinsner at cisco.com>]

Guy,

Would you please expand on 'today's situation'?

What I've gleaned out of Ted's assertion (which is also my understanding)
and NENA's request (from you) is that PSAPs can 'technically' control the
call on wireline service, but not wireless service.  I also believe that
even if the capability is technically feasible, some jurisdictions don't
have the desire to control the call.

I'm struggling when it's the case where the jurisdiction requires call
control, but it is not technically feasible.  Hence, how do you expect the
IETF to support the feature since your are asking to match today's
situation?   Which situation?  The one where it's not technically feasible?
