An access number can contain up to 31 characters, but no unacceptable 
characters such as a letter. At most 100 access numbers can be configured for the 
voice gateway.

The shortest match and exact match are preferred for access number match. If an 
access number template is the same as some voice entity template, the global 
number substitution rules in voice dial program view and those in voice subscriber 
line view will be valid for the access number, but no entity substitution rule can be 
matched in access number view.
