If by conference you mean inside and outside parties connected together the answer is yes. You should have a CONF button on the set. You press CONF, dial your second call and press CONF again. You can press CONF again and do it all over again to add a 4th party. There are restrictions and the conference is not amplified.

Here's a User guide to Partner phones. pdf page 3 has CONFERENCE instructions.

Can the att mls 12d phone system take a T1 card so that i can use it for a VoIP solution?

It can, but why do you need a T1 solution for such a small phone system? VoIP can be delivered on T1, but analog trunks can be broken out to feed the system.

A T1 card can be added to an ACS system. Review the features with your Avaya installer. You'll lose CID if you have it now.
