How to increase # of conference

[vicentell]

Hi Everyone.
I have a Meridian Option 11.
Currently all my phone set are able to get only 4 call at a time. Is there any option that I can change in order to have more than 4, like 7 calls at a time (in conference) in the same phone set.

My phone set models are. 3904,3903,3902 and 3901

for Aries/Taurus sets you need the conferrence key set as A06. This will allow for 6 parties

For analogue sets, set CLS = C6A

You only have two options with 3904’s key 18 can only be AO3 or AO6.
