Answer 1

thanks, but
The cisco ios version is Cisco IOS Software, 2800 Software (C2800NM-SPSERVICESK9-M), Version 12.4(15)T12, RELEASE SOFTWARE (fc3)
and the cme version is CONFIG (Version=4.1(0))
=====================
Version 4.1(0)
Cisco Unified Communications Manager Express
I want to upgrade the cisco ios version to 12.4(22)YB1 and the cme to 7.1 to support the conference ip phone 7937.
There is no enough memory in the flash ,so during the upgrading i will have to comfirm the erasing of the whole
flash .Then i`ll install the new ios and also the new cme version- ofcourse befor that i`ll backup the router
configration..
1- By doing this upgrading , is there something will get affected(like ip phones licenses, basic configurable automated attendant that cme ships with or ....) and does everything will return to work normally?
2-Is there any advices from you to guarantee that i`ll not face any problem...?
3- when outside call ( eg.from my mobile or pstn) dial into the company and the 333(receptionist) phone rings - it is written from unknown number even after i add the command caller-id enable.
