5.  Swapping/Adding/Deleting SVP Servers 

Whenever an SVP Server is removed from the system, Wireless Telephones that are 
using the SVP Server will be affected. If the removal of the SVP Server is intentional, the 
administrator should lock and idle the system prior to removing an SVP Server. 
Whenever an SVP Server is added to the system, the change is seamless and does not 
affect Wireless Telephone calling functionality. 

5.1 IP 

System 

Adding an SVP Server 

In the IP PBX environment, a new SVP Server is detected within two seconds of being 
added to the system (booted/configured/connected). When detected, any Wireless 
Telephone not active in a call will immediately be forced to check-out and check-in 
again. Any Wireless Telephone in a call will immediately switch to the SVP Server that 
should provide its "timing" function. This switch should not be noticeable to the user 
since it is similar to a normal handoff between access points. When the Wireless 
Telephone ends the call, it will be forced to checkout and checkin again.  

Removing an SVP Server 

When an SVP Server is removed from the system it is detected within two seconds. 
Wireless Telephones not in calls are immediately forced to checkout and checkin again. 
For Wireless Telephones active in calls, two possible scenarios can occur. If the SVP 
Server that was removed was providing the "gateway" function for the Wireless 
Telephone, then the call is lost and the Wireless Telephone is forced to checkin again. If 
the SVP Server that was removed was providing the "timing" function for the call, the 
call will switch to the SVP Server that should now provide the "timing" function. Note 
that during the two seconds while the loss of the SVP Server is being detected, the audio 
for the call will be lost.  

Changing the Master SVP Server 

In the event the master SVP Server loses communication with the network, the Wireless 
Telephone system will fail. All SVP Servers will lock and all calls will be lost and no 
calls will be able to be placed. Therefore, if the master SVP Server needs to be replaced, 
be sure the system can be brought down with minimal call interruption. Be sure to reset 
all SVP Servers after the master has been replaced. If the IP address of the master is 
changed, it must be changed in all SVP Servers.
