I have a basic setup question. I am a newbe when it comes to this part of CCM configs. I am setting up a single CCM and Unity system that will service 4 remote sites connected by WAN. Each site will have its own PSTN GW configured in CM
My goal is as follows,
1. All phones should be able to 4 digit dial all other phones at other sites internally
2. At each site when an off net call is placed, it will route out the sites local PSTN GW.
What would be the best way to accomplish this and give me the ability to add sites in the future?
Any ideas and links to examples would be helpful
