I have cisco 2801 spservicek9 with cme 8
I configured CME on this router, and I have already add 30 ephone on this cme
I have also connected 30 IP phone on my network and it work fine
Refer to cisco documentation, cisco 2801 router can support only 25 ip phone, in my case I added 30 ip phone successfully : why the router accept more than 25 ephone ?
Is there a particular risk to have 30 IP phone operating on cisco 2801 CME ?
The stated max users on a 2801 is 25 but there is some cushion here from Cisco that will let you
register up to 30 phones. This is common on all the ISR series and does not pose any
risk to run in this manner. It's like the license overdraft that Cisco allows on CUCM.

Did the Cisco 2801 support the 6921 IP Phones??
I have an IOS 12.4(11)XJ/CME4.1(0), when connecting the Cisco Ip phone 6921 to the network I get an error message saying that" phone not registred", so should Upgrade the CallManager to another release?? I f yes Which one should I use to add the Cisco 6921 ??
I found the upgrade procedure at this link http://www.cisco.com/en/US/products/ps5855/products_tech_note09186a00801fc986.shtml
The problem is when I will upgrade to 15.1(3)T release, the Old Cisco IP phone 7911G installed will be not supported.
