HP VCX Software manual Requests, Default timeout for Invite requests, SIP blacklist interval

Chapter 10. SIP Services

Requests

You can configure timeouts for the different functions of the Telecommuting Module SIP module here. It is not recommended to change from the default values unless you really know what you’re doing.

Default timeout for INVITE requests

When sending an INVITE request you can specify a timeout, telling how long you can wait before getting an answer.

If no timeout is given when an INVITE request is sent, the Telecommuting Module sends the default timeout entered here.

Maximum timeout for INVITE requests

Here, enter the maximum timeout to allow for an INVITE request. If a higher timeout is given, the Telecommuting Module changes it to the value entered here.

SIP blacklist interval

When the Telecommuting Module sends out a SIP request and no reply is received, the SIP peer (say, a SIP server or an IP phone) will be blacklisten for the given time interval. This blacklisting means that no new SIP requests will be sent to the unit, even if requests that should be routed to this unit is received by the Telecommuting Module.

If the SIP request which caused the blacklisting, or a subsequent SIP request for that unit, can be routed to another device instead, the Telecommuting Module will keep on sending those requests to the next known IP address for the domain/user in question. When the blacklist ends, the Telecommuting Module will go back to sending requests to the previously blacklisted unit again.

If a 0 is entered into this field, the SIP blacklisting will not be used by the Telecommuting Module.
