I need your help for Cisco CallManager express.
l have two sites connected via leased line.
On main site (site A ) l have a 2800 series router with CallManager express , one Cisco 2960 switch and few Cisco IP iPhone (SPA 525 G2). What l want now is to deploy 2 IP iphones on the second site (site B).
On this second site I have a firewall ASA 5505, one Cisco switch 2960 and two IP phones . I don't have à CallManager on this site. I need to allow call between two sites sites.
is it possible to use only site A CallManager express for managing call for two sites? My network is a small one, and finally we will have a maximum of 20 phones on all sites.
I need your feedback, your experience and will appreciate all ideas.
I'm a beginner with Cisco VOIP and that is my first project on this tools.
