I need to ring a group of 8 phones, but not if they are already on

I only ring the others?
I've done this in the past by disabling call waiting on the phones and put
all 8 phones into a "ringall" queue. Then, when you call that queue, the
phones already on calls return SIP BUSY,whilst the others ring as normal.
It's not perfect, but for most of our users the call waiting noise in the
earpiece is an annoyance anyway.
Hope that helps.

If you disable call waiting, then you don't need a queue.
With grandstream gxp-2000 phones, calling
Dial(SIP/phone1&SIP/phone2&SIP/phone3....)
rings only off-hook phones.
However, I have also SPA-941 phones.
Is it possible to disable the call waiting feature on Linksys SPA-941?
I haven't succeeded so far... and the multiple Dial() method or
the Queue are not working either.
I had to change my extensions.conf macro to do ChanIsAvail sequentially,
that is, for each phone I call ChanIsAvail and then check the results
to see if the phone is busy. If not, I add it to the dialstring to
pass to Dial() eventually.
Since there are 10 phones to check, and the process is not atomic,
it can (very rarely) occur that a phone is included in the dialstring
but has just become busy, and the user gets the annoying call waiting
tone.
Any clue?
