Does anyone know how to calculate Router capacity to support IP Phone?
We are now running CallManager 4.2 on MCS7825. From document this can support up to 1000 IP Phone.
And we have R2851 with 3 E1 port and R2821 with 2 E1 port.
Currently we are using about 100 IP Phone and we'd like to add about 200 more.
Will the router able to support this amount of IP Phone? Do i need to add any other component?
Your help is much appreciate.
