We are trying to add phones to our CME 4.0, and it looks like we are max out at 42 phones. Althought this http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/requirements/guide/33matrix.htm link tells us the max is 36. So I don't know how we got 8 more phones on. Because this is a small office, we only need to add 5 or 6 more phones. This is what we got:
2811 with NM-CUE module, Software: 12.4(4)XC / CME 4.0(1)
So my questions are is it possible to upgrade the software or module to support a few more phones, or is it possible to tweak the system? Again, we are only try to add a few more phones. Is there a third party route i am be able to take?
Thanks for your time and help,
