I have one UC 500 with 48 users in site A and in site B I have a cisco 877W and spa9000 for IP telephony; (only 12 users)
I want to communicate both sites with IP telephony and I was thinking with vpn tunnel is the best option for de Site A call to Site B reading.
(Maybe if I haven't fixed IP address in site A and B, I Cam use some DyNDNS service?)
dial-peer voice (extention_in_siteA)
session target ipv4:(IP_in_SiteB)
dial-peer voice (extention_in_siteB)
