The following table shows the supported IPNC Callback types. 

Disable (Default) 

Callback is not enabled 
 

LCP 
Link Control Protocol 

After authentication the incoming call is 
dropped and an outgoing call to the 
number configured in the Service will 
be made to re-establish the link. 
 

Callback CP 
Microsoft's Callback Control Protocol 

 After acceptance from both ends the 
incoming call is dropped and an 
outgoing call to the number configured 
in the Service will be made to re-
establish the link. 
 

Extended CBCP 
Extended Callback Control Protocol 

Similar to Callback CP however the 
Microsoft application at the remote end 
will prompt for a telephone number. An 
outgoing call will then be made to that 
number to re-establish the link. 
 

 

The following points must be noted for Callback functionality 
• 

Callback for an incoming call is configured on a RAS and for an outgoing is 
configured on the Service. 

• 

For an incoming call the Callback option need NOT be set on the Service. 
Setting Callback on a Service allows the IPNC to negotiate Callback when 
initiating the call. 

• 

For all Callback types an intranet service type must be used. 

• 

To support a mixed environment where some incoming calls do not require 
Callback a separate RAS’es must be configured (with a unique DDI) with and 
without Callback enabled. 

• 

Certain Callback types maybe configured to circumnavigate Time profile 
restrictions.
