Re: cisco wireless phone - cisco call manager

Hi there

 

Your running CME is 10.5 which got end of life/sale. You should plan moving towards the 12.6 now with 4300 or 4400 ISRs. You can get the max limit capacities from below doc

https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/requirements/guide/cme126spc.html

 

For Wireless phones, you can plan 8821 and if you dont plan for an existing CME upgrade, you can try deploying using fast track mode on 10.5

You can find the max limit of your CME 10.5/ Router model from here.

Hope this Helps

i have 25 seat license ? and i already installed 16 phones ? so should request the wireless phones without licenses ?

Re: cisco wireless phone - cisco call manager

amralrazzaz, 

 

Ratheesh's answer was pretty inclusive. I am not completely familiar with CME licensing, but if you have 25 seats and are only using 24, you would have 1 license available for a wireless phone. You can use the 7920, 21, 25, 26 or the 8821. If the price is right on the secondary market, and they offer the license with it, then that is up to you. I personally would have concerns uploading licenses from a secondary source. Make sure it is reputable. Since you aren't planning on upgrading though you won't be able to get the licenses from Cisco.

 

This link will tell you what is compatible. Good luck.

Re: cisco wireless phone - cisco call manager

Amr Alrazzaz,

 

If you are currently using SCCP and have never used SIP then stay with SCCP. If you have used or are using SIP currently and are comfortable with it, then the choice is yours based upon what you need from the phone. Both phones work through at least CME 12.0 and have not been deprecated.

Re: cisco wireless phone - cisco call manager

Personally I would go to 12.5. It has been my experience that the mid versions are better. 12.5 is the version where they work out all the issues or most of the issues with 12.0, same with 11.5 compared to 11.0.
