A Mediation Server pool must have a uniform view of the peer gateway with which it interacts. Media bypass also decreases the processing load on the pool. Acting as an intermediary for call flows that a gateway does not support, such as calls from remote workers on an Enterprise Voice clien.

Where a remote site without a Mediation Server is connected to a central site by one or more WAN links with constrained bandwidth, media bypass lowers the bandwidth requirement by enabling media from a client at a remote site to flow directly to its local gateway without first having to flow across the WAN link to a Mediation Server at the central site and back. If your environment cannot meet these requirements, then you must deploy a stand-alone Mediation Server pool.

Assume that Skype for Business users exist at both Sites 1 and 2. In this topology, media bypass is enabled globally to use site and region information, and the trunks to the PBX and PSTN gateway have media bypass enabled.


N trunks, media bypass, and call admission control. Media bypass and call admission control CAC are mutually exclusive.


If that is not possible for example, if the locality of the ultimate media endpoint on the gateway side is unknown for an outgoing call to the gateway peer , bandwidth is reserved when the call is placed. The assumption is that there are no links with constrained bandwidth involved in the call. Therefore, there is no way to segment the pool so that some Mediation Servers communicate with only certain gateway peers for outgoing calls.

Media bypass and bandwidth reservation are mutually exclusive. Furthermore, the service provider may charge extra for this capability. When a Mediation Server is collocated with a Front End pool, the pool size can be at most 12 the limit of the Registrar pool size.

Our new feedback system is built on GitHub Issues. However, if you can enable media bypass, doing so will reduce media path latency and improve the media quality because the media path is no longer required to follow the signaling path. To support this, the Mediation Server is responsible for bandwidth management for its two interactions on the Skype for Business Server side and on the gateway side.

N trunk in Skype for Business Server Media bypass and bandwidth reservation are mutually exclusive. Read about this change in our blog post.



The following figure shows the signaling and media protocols that are used by the Mediation Server when communicating with a basic PSTN gateway and the Enterprise Voice infrastructure. When a Mediation Server is collocated with a Front End pool, the pool size can be at most 12 the limit of the Registrar pool size. The assumption here is that there are no links with constrained bandwidth involved in the call.

A Mediation Server can have multiple trunks to the same gateway; a Mediation Server can have multiple trunks to different gateways; conversely a gateway can have multiple trunks to different Mediation Servers. This issue can be more severe if a Mediation Server at a central site is routing calls for an IP-PBX where the route terminates at a branch site, because more time is needed for signaling to complete.

По моему мнению Вы не правы. Могу отстоять свою позицию. Пишите мне в PM, обсудим.
