I'm unfamiliar and newbie to the VOIP system and need to setup small system for branch office.
I've just dug out a few related post from here (thank you netpro) and would like to ask a few question.
Here's the most similar example for my case.
please see the attach for sample diagram.
How can I configure for all international outgoing and incoming call ( with/without CUCM connection somewhere) in my router ?
Is it possible to configure all the call routing inside PBX ?
Please advise me how to set up in simplest way.
Thanks in advance
