You got a lot further than I did on this implementation of Wowza. I have not been able to connect to the stream from Kaltura to Wowza. I have managed to connect to Wowza to Kaltura with no issue. I think my issue is related to proper configuration of the authentication process. So you are on a good start.
As for the token I thought thid value was the base URL you use to connect to your Wowza server from the web. Some people use IPs and other configure a TLD or Sub Domain to connect to the host.
