Dialer-Plan
Hi all,
i'm very new user to work on voice.Recently, i'm starting work on VOIP.My company has taken a project to implement a project for data and voice with the help of Cisco ISRs [3845,2851,2821,2811].
Initialy i'm working on dialer-plan for Voice.
summary of project:-
We are going to make a tree type network of cisco isrs.we are using VPN Tunnel on Ospf multiarea network.We are going to use 2 cisco 3845 on 1st level, 14 cisco 2851 on 2nd level, 33 cisco 2821 on 3rd level and 51 cisco 2811 on 4rth level of tree network. EPBX will work on all routers with maximum 10 extention numbers.
Now i'm planning to create a dialer plan for this voice network.I've done some initial exercise.Kindly suggest me to finalise this dialer plan.
