This type of line is used to create a SIP connection between an IP Office and an Avaya Aura® Session Manager. The other end of the SIP connection must be configured on the Session Manager as a SIP Entity Link.

An SM Line can only be added to IP Office system Standard Mode or Server Edition configurations. It is typically used in IP Office Standard mode in Enterprise Branch deployments connected to the Avaya Aura® network. For more details about IP Office Enterprise Branch deployments refer to Deploying Avaya IP Office™ Platform as an Enterprise Branch with Avaya Aura® Session Manager.

An SM Line can also be used in IP Office Server Edition to connect to an Avaya Aura® Session Manager. Through the SM Line, IP Office Server Edition supports interoperability with Avaya Aura® Session Manager. It also supports interoperability, via the Avaya Aura® Session Manager, with Avaya Aura® Communication Manager systems and with CS 1000 systems. Note that IP Office Server Edition is not used as an enterprise branch product and does not support some of the IP Office enterprise branch functionality, such as management by Avaya Aura® System Manager, WebLM licensing, Centralized Users or voicemail over the SM Line.

If the Avaya Aura® network has multiple Avaya Aura® Session Managers to provide redundancy, two SM lines can be added, one configured for each Avaya Aura® Session Manager.
