To inter-operate with virtualized desktop solutions such as a Citrix server hosting 1xC or an Ascom IPVM, the Endpoint Concentrator (endpt conc) connection policy provides for up to 4000 connections from a single IP address.

You can assign the Endpoint Concentrator connection policy to a SIP entity link. The Session Manager (ASSET) allows up to 4000 connections on that SIP entity link.

The Endpoint Concentrator policy is an untrusted policy based on the current Default (endpoint) policy. The requests arriving over the SIP entity link with the endpt conc connection policy are challenged similar to any other endpoint.

When the customer administers a SIP entity as an Endpoint Concentrator on the SIP entity page, all subsequently added SIP entity links towards that entity will have the endpt conc connection policy by default.

The endpt conc policy cannot be used for remote office (REMO) configurations. With a REMO configuration, the Session Border Controller servers use a single connection in the SIP entity link towards Session Manager to multiplex multiple calls. For such configurations, the connection policy must allocate large amounts of memory and buffers for a single connection.
