将思科7912G SIP电话转成SCCP模式(Converting an In-Use Phone from SIP to SCCP for IP Phone 7912G)

最近将Cisco 7912G转成SIP形式后，发现少了很多功能，而且成了英文。想再转换成SCCP模式后，发现并不是想像中的那么容易。

 

网上找了很多方式，最后终于找到答案了，转换成功。摘录如下：

 

环境：CUCM 6.1 + 7912G

 

1. In Cisco Unified Callmanager Administration, choose Device > Phone.

 

2. Click on the existing SIP phone that you want to convert to SCCP.

 

3. In Phone Configuration page, enter the SCCP image name for the phone model in the Phone Load Name field.

 

--------------------------------------------------------------------------------

 

Note You can view a list of the default image names for all phone models by choosing Device > Device Settings > Device Defaults in Cisco Unified CallManager Administration.

 

--------------------------------------------------------------------------------

 

4. Click Save.

 

--------------------------------------------------------------------------------

 

Note A pop-up window will tell you to reset the phone for the changes to apply.

 

--------------------------------------------------------------------------------

 

5. Click Reset.

 

6. In the Device Reset page, click Reset, then click Close.

 

--------------------------------------------------------------------------------

 

Note The phone will reboot and upgrade to the SCCP image. When the phone completes the reboot process, the message "Registration Rejected" appears. Do not proceed until this message appears.

 

--------------------------------------------------------------------------------

 

7. Click Delete to remove the SIP phone configuration from Cisco Unified CallManager.

 

8. Perform a factory reset on the phone:

 

     8a. Press the MENU button.

 

     8b. Press **2

 

     8c. When you receive the prompt: "Do you want to reset all system settings to default values?", press the Yes softkey.
