Use the Session Initiation Protocol (SIP) application router to select the order in which SIP applications are triggered. When configuring a SIP application router, you can either use the default application router or create a custom application router.
The following information explains how to configure a custom application router to route to the commsvc system application. The examples show a custom application router configuration with and without the commsvc application.
INVITE: ("TestB2bua", "DAR:To", "NEUTRAL", "", "NO_ROUTE", "0")
The first element after the INVITE is the display name of the test application, and this one-line application router routes b2bua calls to the application successfully. With the preceding application router configured on the SIP container, however, CEA Web collaboration attempts fail.INVITE: ("TestB2bua", "DAR:To", "NEUTRAL", "", "NO_ROUTE", "0"),("commsvc", "DAR:To", "NEUTRAL", "", "NO_ROUTE", "0")
This action ensures that CEA messages are routed correctly.You can either use the DAR or a custom application router to perform application routing, as described in the procedure.
Use the following procedure to select the best method to implement the SIP application router for your configuration.
