[asterisk-users] Call Presence for Offhook/Onhook Only

[Danny Nicholas]

You could do a simple PHP/Perl script to query hints and ring only the
not-in-use phones.  Or more simply that that do a ChanIsAvail() against the
list and ring the returned array. If I do
ChanIsAvail(line1/line2/line3/line4/line5) and 1 and 3 are in use, it
returns an array with 2/4/5 and I can Dial the array.

We have a customer with a dozen phones and they want nearly all of them to
ring.    Unfortunately this causes a firestorm of call presence
notifications that overwhelm something on their network.   Any existing
calls get gappy audio for a few milliseconds when a new call comes in and
when someone picks it up due to all the state changes between ringing and
not ringing.  They have a T-1 dedicated to voice so it isn't a bandwidth
issue per se.   We've been through a handful of routers and QOS settings but
nothing has worked.   Turning off the busy lamps fixes the problem but of
course that isn't really a long term solution.

Really I don't think anyone cares about the busy lamps for ringing.   They
just want to know when someone is on the phone.

Is there any way short of hacking code that we can make notifications ignore
changes involving ringing and just report inuse/notinuse?

We are using 1.8.x if that matters.
