Hello everyone
I'm sorry if my question was so poor. I'm quite new to these voices technology. So I need an exact understanding about this. What is the difference between trunk and a gateway (voice gateway)? when should I use them?
My topology is :
PSTN ======= VG (FXO) ====== Layer 3 Switch ======= CUCM
(0352)488xxx III III
IP Phone IP Phone
(10001) (10002)
When i want to make an inbound call from outside to my DN 10001, or vice versa (my DN make an outbound call to outside), which one should i use? trunk? or gateway? or maybe both?
Thanks for the answer

There is a lot of personal opinion of which protocol is best. I use SIP for everything but that isn’t a universal belief.
