Title: MBG Media Anchoring Disable
Post by: pradeepgali on October 14, 2014, 04:08:51 PM

I am trying to disable media anchoring in Mitel Border Gateway. I tried setting Local Streaming to "True" in SIP Trunk settings and Local Streaming to True in "Configuration > Settings > SIP Options to True  and restarted MBG. These change did not change the call behavior.
Am i missing some thing? Please help me.

We have a customer requirement that MBG should not anchor media(Media Bypass enable in MBG). The RTP streams should not pass through the MBG. As per the document in MBG, i found a place to execute this. When we Local Streaming in SIP Trunk Settings to "True", MBG will bypass the media streaming. But this is not happening. irrespective of this setting, the media is passing through MBG.

Please find the attached image for reference.

I think you will find that this only applies to local MiNet devices (Mitel IP Phones). i.e. RTP will stream directly between devices.
This is to save bandwidth on remote phones in the same network as they won't stream RTP to the MBG and back again.

The purpose of MBG is to proxy voice traffic.

Not sure if it does what you are asking.

If you don't want the RTP stream to flow through the MBG then just remove the MBG from being a proxy under the SIP peer profile.

If you are using the proxy though, then that is exactly what MBG is for, and the media needs to stream through it.

Is there an actual reason for them not wanting it to be flowing through the MBG?

From what I gather, the local streaming would best apply to remote teleworkers behind the same nat address. If they dialed each other, the MBG would proxy the request to the controller, the call would be setup and the end result would be the RTP traffic would go between the 2 stations, as in private address to private address.

If a SIP trunk was proxied throught the MBG, it would still be involved.
