Hello all, Sorry for being very green. But I inherited a Cisco Unity Express phone system 2.1. We are trying to add some more phones, but are unable to getting the following error message "Registration Rejected: Max Phone". What i know so far is the Cisco CallManager is on the router and the verison is Cisco Unity Express Version 2.1. Software: 12.4(4)XC / CME 4.0(1)
What is the best way to fix this problem?
Thanks for your time and help,
Under telephony-service you can check with max-ephone how many phones you can add: http://cisco.biz/en/US/docs/voice_ip_comm/cucme/command/reference/cme_m1ht.html#wp1094681
If you can't add more, you need bigger router capable of registering more phones.

Hope it helps, please rate if it does.
