Hi Simon, at this point, Jabber Voice does not support barge. I don't think the jabber clients can handle the 2 simultaneous media streams.
Per the Cisco Jabber Deployment guide, it is not supported:
"You can use silent monitoring and call recording functionality only. Cisco Jabber does not support other functionality such as barging or whisper coaching. "
are you referring to Jabber Voice client on iPhone and Android in your specific query? Or is it a question for all Jabber products?
Thanks a lot.
I am referring all the kinds of Jabber client: Jabber for Wind/Mac, Jabber for ipad, Jabber for iphone, Jabber for Android.
Neither of them support the "Barge", right?
