sorry for not beeing specific enough. Of course RFC3326 allows to ignore all kind of flags.
My SPA302D is part of a call group, if I pick up a call on a different phone. The device shows a missed call. It would be nice to have a function to either completely disable the display of missed calls (for me it doesn't matter if it is recorded in it's internal database) or have it ignored by the example given in the RFC 3326 under to 3.1.
I found it when I analyzed why I can't dial '#' as last 'digit' of called number from DECT handset. Example in #21# supplemental service code.
But back to the core of problem. As I told, I'm out of my test lab, so I have no access to my SPA232/302D. I described how it works on SPA504G as we have it here and we use such feature on it. The SPA5xx and SPA232 behavior is very simmilar, so if such feature is implemented at all, then it is implemented the same way.
On the other side SPA232 is the same ATA as SPA122, just DECT interface added. There is no way to signal "answered elsewhere" on POTS lines, so the feature in question may not be implemented at all because it's not possible to relay the information to connected phone. It apply to DECT as well, unless extended by a proprietary cause code.
In my humble opinion, there is a little chance the feature you asked about is implemented. But you can hope, of course. Just try it.
By the way, You are true, there is no type=private/shared option on SPA232 so forged about such option. and try without it.
