Configuring The Callback Client - HP MSR Router Series Wan Access Configuration Manual

To provide enough time for a server to call back, make sure the holddown timer on the client is at
•
least 10 seconds longer than that on the server. HP recommends setting the holddown timer to 5
seconds (the default) on the server and to 15 seconds on the client.
• Do not configure dynamic route backup on the interface. Otherwise, the interface does not accept
incoming calls or outgoing calls other than those that are initiated for the dynamic route backup
feature.
