Phone models features list

Hi All,

I am new to the forum. I have not worked much with yealinks and I am trying to familiarize myself with the phones. My new workplace uses the following models
T19P
T20P
T21P
T22P
T26P
T28P
T32G
T38G
T41P
T42G
T46G
T48G
W52P
T27P

I am trying to see if I can find a list of the features of each phone. My main concerns are if the phones support an SRV record template,Call Park.BLF.Directed Pickup,Multicast paging and Intercom.

Is there somewhere I could find this information on a product comparision sheet?

Thanks!
