SIP Profile - Reattempt Invite On Error
Â
Â
The SIP Reattempt Invite On Error configurable options adds ability to reattempt based on response code when using DNS to receive a list of routing options. When using DNS and receiving a list of endpoints to send the call to IMG 2020, there are configurable options that would allow reattempt when receiving various SIP responses.
The configuration can be performed from the SIP Profile (SGP). The options include Reattempt with next DNS entry on Response Code 4XX, 5XX, and 6XX. Each of these properties is associated with a multiple selection interface which allows the user to individually select the response code.
Additionally, the user can select all the responses of a specific type (4XX, 5XX, or 6XX). It will also be possible to select all error codes that are not listed in the multiple selections dialog, in case unsupported response codes need to be taken in account to reattempt the call.
