I am unable to involve the third party in a conference call, all the parties are analog lines connected to a 3300 via a peripheral cabin, Berkshire 800 phones are used,
all the recommended settings in the system options and COS of the are set properly,
The phones flash well,
I can put the called party on hold and retrieve him back, i can transfer him to a local or remote number or even to a CO trunk,
But still unable making any conference call,
Any insight would be appreciated,
