I am ordering a voice PRI for my office. I am using a Cisco 2821 H323 voice gateway router and a CUCM 7.1.5 server. The provider asked me two questions that I am unsure of:
1. How many digits do you want to send. They said I can do 3, 4, or 10. Can someone please explain this?
2. What protocol do I want to use. I wasn't sure so they picked NI2. Will this work my an H323 gateway?
