Configuring a Routing Response Timeout

If you have routing rules in the IP-to-IP Routing table that need to query external servers (e.g., LDAP server, ENUM server, or HTTP GET method requests) on whose responses the device uses to determine where to route the SBC calls, you can configure a timeout for the responses. If the timeout expires before the device receives a response, the device sends a routing failure message (SIP 500) to the caller or uses an alternative routing rule (if configured).

To configure a timeout for routing query responses:
1. Open the SBC General Settings page (Setup menu > Signaling & Media tab > SBC folder > SBC General Settings).
2. In the 'Routing Timeout' [SbcRoutingTimeout] field, enter the maximum duration (in seconds) that the device is prepared to wait for a response from external servers.

3. Click Apply.
