Here’s how to reboot Cisco 79XX series IP phones:
- Phones running SIP: press and hold *, 6 and the settings button
- Phones running SCCP: press , , #, * and *

From the sourceforge website:
Cisco IP Phone Inventory Tool: Inventories Cisco SCCP IP phones->outputs .CSV file with the following information: IP Address, Model Number, MAC Address, Host Name, Phone DN, Phone Load Version, Phone Serial Number, and switch name, ip, and port information
A promising tool which can be found here: http://sourceforge.net/projects/cipinventory/.
This tool however, requires access to network components. You can also gather this info by querying the CUCM servers directly, just like so:
admin:show risdb query phone

Ever wondered how many of your telephony devices are located outside of their home location (as configured on the device when using the Device Mobility feature)?
Here’s how: log on to the CUCM CLI and run the following query:
run sql select d.name, d.description, dp.name from devicemobilitydynamic dmd, device d, devicepool dp where dmd.fkdevice = d.pkid and dmd.fkdevicepool_devicemobility = dp.pkid
This will produce output like:
name description name
=============== ===================== =====
SEP0016466166B8 Phone 77640 HQ
SEP001E156CF34B Phone 79117 HQ
SEP001149604BFA Phone 77666 HQ
SEP0015FFFF5B38 Phone 77685 HQ
What this means is that the given devices are put in the HQ Device Pool (according to the Device Mobility setup) while they have another Device Pool configured. To remedy this solution, you should reconfigure those devices so they belong to the HQ Device Pool. You’ll probably need to change the Location and Device Calling Search Space settings as well.
This has been tested with CUCM 6.

After upgrading a few VG224′s the other day, I noticed that some of the VG’s were not working properly (e.g. no dialtone, unreachable DN’s, etc.). After some investigation I noticed that there were problems concerning the DSP’s in the VG (VG224′s have 3 DSP’s on board as opposed to voicerouters where they are separate modules). The logging showed:
172.16.16.13-20120329.log:2012-03-29T17:15:30.940236+02:00 172.16.16.13 50: .Mar 29 2012 17:15:29: %FLEXDSPRM-5-OUT_OF_RESOURCES: No dsps found either locally or globally.

Also, when reloading a VG, I noticed that the DSP’s did not always come online. In some cases all the DSP’s were down (which would be indicated by the logging above).
Further investigation can be done with the following statements:

When looking at the running config, you might see a statement that points you in the right direction:
HK-0#
! Warning! DSPs 1,2,3 in slot 0 are using non-default firmware from device flash:
! This is not recommended, the IOS default version is 24.3.7
You can also have a look here: https://supportforums.cisco.com/thread/278921.
To remedy the problem, the best course of action is to contact Cisco TAC and present your findings. TAC will probably provide you with ‘DSP ware’ apropriate for your IOS version AND you DSP hardware (several types of DSP’s exist).
