Are you referring to this section in the IPMA docs regarding the IPMA 
Service Parameter configuration?

Proxy Directory Number Prefix

  –Number of Characters to be Stripped from Manager Directory 
Number—Default specifies 0. This parameter specifies the number of 
characters that Cisco CallManager strips from a manager IPMA directory 
number (DN) in the process of generating a proxy DN. You can use this 
parameter along with the Prefix for Manager Directory Number parameter 
to generate a proxy DN. For example, if you strip 2 digits from a 
manager DN of 2002 and add a prefix of 30 (specified in the Prefix for 
Manager Directory Number service parameter), Cisco CallManager 
generates a proxy DN of 3002. You can strip 0 to 24 characters.

  –Prefix for Manager Directory Number—No default. This parameter 
specifies the prefix that Cisco CallManager adds to a manager DN in the 
process of generating the proxy DN. For example, if manager DN is 1001, 
number of characters to be stripped is 0, and the prefix is *, 
Cisco CallManager generates a proxy DN of *1001. The maximum prefix 
length equals 24.

There is no requirement for an *. I think this is just an example of 
what you could do.  The only reason I can think of to do this is to 
keep most people from dialing the number.  Just my opinion though.
