AK,

2811 supports max of:

36 SCCP Phones

144 Ephone-DNs

CME is not a so bug free setup, so i recommend to follow the guidelines from the cisco site:

Hope it helped

Regards.

Actually a 2811 should support only 36 phones, and will not support more than that (actually a bit more, type ? after max-ephones).

There are no licenses that you can buy to increase that number.

As a workaround you can configure additional phones in SIP, but I would NOT recommend that and you should buy a bigger router instead.

Hope this helps, please rate post if it does!

Wat about Cisco 2821 (revision 53.51) with 249856K/12288K bytes of memory.

Is it restricted to 48 IP phones ?

thanks

Actually 52, because Cisco allow form some excess from the marketed numbers.
