Hello,

Say for example you have 10/12 clients in same prefix. Some carriers sending wholsale or mixed traffic and some are sending only pure retail traffic. Which one you are over 100% sure and you want those client only pass in the route(vendor) who accept only retail calls like Pakistan Non CLI, Nepal Non CLI or african vendors. Simply you can do it by allowing those client(mapping gw) in VOS3000. So you do not need to change prefix or no need to use many prefix. This is very simple as well, just follow the images below:
