Cisco Systems OL-10984-01 Manuale Utente

The Merge button is active only when more than one conversation is in 
progress, and only in the conversation window of the active conversation. 

Video conversations become audio-only after merging. 

When you merge a conversation that includes web conferencing, make sure 
the conversation with web conferencing is NOT the active conversation when 
you merge the conversations. 

If you merge two conversations and subsequently hang up, the other 
participants can continue the conference call. 

Choose the conversation that you want to keep, and put it on hold. For example, 
if one conversation includes web conferencing or multiple participants, put that 
conversation on hold. 

Make the other conversation active. 

Merge the conversations using one of the following methods: 

In the active conversation window, click the Merge button. 

Choose Conversation > Merge. 

Choose the person with whose conversation you want to merge. 

The  conversation that was on hold becomes the active conversation; all 
participants are in it.
