Configuring The Local Sip Server To Operate In The Alive Mode (Method 2) - HP FlexNetwork MSR Series Configuration Manual

If the link between Router C and VCX is disconnected, Phone 1000 and Phone 5000 can
register with the local SIP server again to originate calls.
Configuring the local SIP server to operate in the alive mode
(method 2)
Network requirements
Router A and Router B carry out call services through the VCX. Configure Router A to operate in the
local SIP server alive mode. When the IP link between Router A and VCX fails, the local SIP server
on Router A accepts registrations from its attached phones to make sure the phones can initiate and
receive calls through Router A. When the IP link between Router A and VCX recovers, the local SIP
server on Router A is disabled, and the attached phones re-register with the VCX. See
