Subject: R1 Package

A couple of questions/comments to Tom and also Kushanava.

1. Given the request for last call on the R2 package and request to make the R1 package a work-group item: Is the intent for to cover CAS in general within the work group?

2. Is the R1 expected to be the basis for other North American CAS (MF wink start, immediate start, DTMF wink start, Immediate start, FGC, FGD) - or only ITU Q.3xx?

3. draft-hss-megaco-r1package-00.txt indicates that the MG adds and strips the KP and ST without the MGC having to worry about it. In the case of FGD MF - the MGC has to supply the KP and ST on sending (could be ST' or ST'' or ST''' - all of which have a different meaning) - similar on receipt - the MGC has to receive those (can't strip them and throw them away) - so if the intent is to use this R1 package as the basis for North American CAS, this is a problem. If a completely separate package (or packages) can be presented - then OK.

4. Using a digit map for MF CAS is unnecessary and inconvenient. Digit strings are already delimited by the ST. It's easier and more convenient to simply accumulate the digits and report the digit string when the ST arrives.
