[cisco-voip] ISDN PRI Protocol Selection

[Kris Seraphine]

Hi
 
When ordering a voice PRI for basic PSTN access, I'm usually asked
choose either national or custom as the protocol.  In a CCM 4
environment, are there reasons to choose one over the other?  I know
that they support calling name id differently but I don't know if one
method is better than the other.
 
thanks

Kris Seraphine
