I would appreciate if folks would share their experiences running VOIP between international sites.
1. Is it necessary to have seperate CCM clusters if you have offices in both the U.S. and the Philippines?
2. Is it necessary to have a true MPLS network connecting the sites?
3. Has anyone tried to run VOIP calls over the Internet (via IPsec tunnels between locations)? If so, what was the voice quality like the majority of the time?
thanks in advance,
