Hi Paul,
If they were using Analog on the Nortel...then you may be able to
duplicate that on the VG224 using this feature/setting
cBarge and Privacy for Shared Lines
The cBarge feature allows any idle IP or analog phone on a shared line or connected to the same port to automatically join an already active call on the same shared line by simply going offhook. Through the Cisco Unified CM, the three parties are allowed to hold a conference call.
Note 
Only one analog phone is allowed to cBarge into an active call. When one phone has already been allowed to cBarge into an existing conversation, no other shared line analog phone can cBarge into it.
In analog switching systems, a single analog port can be connected to multiple analog phones such that when a phone is in an active conversation, any other phone that is connected to the same port can go offhook to join in the conversation.
In digital IP switching (or PBX) systems, a similar capability is supported and it is called a shared line. All the phones using the same directory number are called shared line phones. When there is an existing conversation on a shared line, going offhook enables another shared line phone to cBarge into the conversation.
Note When cBarge is configured, privacy might be an issue because any idle phone on the shared line that goes offhook can join an existing conversation regardless of the idle phone user's desire to join the call or not.
Privacy is a feature that blocks other phones on a shared line to cBarge into a conversation.
Configuring the port on a shared line on the Cisco Unified CM to Privacy prevents other phones on the shared line to barge into active calls.
