You can apply origination and termination application sequencing for SIP (explicit) users based on implicit user application sequencing definitions.

During origination, Session Manager sequences through explicit, then implicit origination applications.

During termination, Session Manager sequences through implicit, then explicit termination applications.

For backwards compatibility, implicit sequencing for SIP users is disabled by default.

Implicit sequencing for a SIP user is performed from the Session Manager associated with the user only. For non-SIP users, any Session Manager can perform implicit sequencing.

Implicit sequencing can route-through to an alternate Session Manager to reach an application. For a SIP user, route-through is limited to the Session Manager instances in the user’s community.
