Re: [Ecrit] Charter & Milestones update - Comments sought

["Gellens, Randall" <[e-mail]>]

The current NENA document on policy-based routing only deals with legacy capabilities (that is, call diversion/exception handling).  The NENA group intends to produce a version two that covers NG9-1-1 (NENA i3) capabilities with the enhancements for call processing including media and other needs.

Hi Gunnar,

that's fine with me but where do you want to add this remark in the
charter text Roger proposed?

Also, do we have any specific document in progress that is impacted by
policy based routing?

Ciao
Hannes
