Re: [Ecrit] Additional Call Data: Info Package

I was asked in the room to send the pointer to the email that proposes an info-package addition to additional-data-subnot.  It was easier to just repost this message that Christer sent earlier this month reminding folks to comment on his text.

Hi,

I’d like to remind those interested about the Info Package text, for providing additional call data, that I sent on the list in November (as requested in Vancouver).

Regards,

Subject: [Ecrit] Additional Call Data: Info Package

Hi,

I put together the first version of an Info Package used to send Additional Call Data for an emergency call, using INFO requests.

At this point I have not written a draft, because I think it would fit in draft-rosen-ecrit-addldata-subnot, eventhough we may want to change/remove the “subnot” part in the draft name.

Regards,

Christer
