I have a customer with a Partner ACS (R6 I believe). A couple times a week several people in the office call into the same conference bridge independently from their own offices/extensions. They only have 4 CO lines but often need more then that so they discovered that one person could initiate the call and the others could hop on the same active CO line to "join" the conference. They do not have automatic extension privacy active and are ok with that. They discovered that only 3 total people can get on the same CO line. Is there a system setting that I can change to increase that? If not then they can just use another CO line and call in.
I think your looking at system resources. Two co lines may have he same limitations . If you look at the conference feature it says you are limited to two inside party' s . that's pretty much what you are seeing .
Partner is a great little system but it doesn't do much more than the basics.
You're not using the conference feature, just a bunch of extensions picking up the same line to join the conversation, right? Line buttons flash red and green? I don't believe there is a limit, I've certainly seen many more than three on the same line. Is this happening with certain extensions or at random, any three then try to add a fourth? (Trying to find a pattern here.) I can't think of any setting that would have anything to do with this. How many extensions do you have and what phones?

Volume is also a problem as more users share a line. Volume drops quickly.
Maybe the next upgrade will fix that,
Oh wait, the best SMB system ever made has been end of life.
It's the limitation of JOINING a call (Barging in) vs. setting up a CONFERENCE call
A conference call connects up to five parties (including the conference
originator) in a single call. Users can connect both outside and inside parties in a conference call,
but the call cannot include more than two outside parties.
Joining is adding yourself to a call in progress, the same way you do on a home telephone by
picking up an extension. (This is different from conferencing, in which the originator “pulls you intoâ€
the call.) Up to three system extensions can join a call on an outside line (for a total of one outside
and four inside parties).
I never realized that! Just to answer this question, I went and took 4 extensions off hook (because the OP said 3) and they all worked. So I thought something must be wrong. Should have gone off-hook with one more and that would have answered the question.
