Got a noob question.
I have a group of offices in regional QLD, highest speed available ADSL2. I have installed 2 Yealink video phones in the main office and one branch office and setup a trixbox sip proxy in our datacentre at the aggregation point of the ADSL2 connections. Quality is great they say, works a treat.
Now the question they and I have is…
If they were to install 4 more phones in 4 other branch offices and the main office created a conference call, would the main office still only have 1 data stream to the sip proxy, still only using the same amount of bandwdith as one office to office call and then distribute off at the proxy? or will 5 individual streams need to come from the main office, probably consuming and running out of bandwidth?
Cheers for any help and advice.
