Cisco SIP Phones Admin Password removal CME [TCLSH Operation]

On this one I wanted to share a really nice way to remove the Admin password from Cisco SIP phones.

It really is annoying to type the Admin password every time you need to modify or at least take a look at the configuration on your phone.

As you may know when you configure a SIP phone on CME you need to give it a username and password, also SIP is kind enough to publish the SEPXXXXX.cnf.xml file to Flash

So here are the steps:

1- Locate your SEPXXXXXXX.cnf.xml file on flash:

CORE#sh flash: | inc SEP

2- Now that you have located your SEP file, its time to expose the contents of the file

CORE#more flash:SEPXXXXXXXX.cnf.xml

3- This will display an output like this

<timeZone>US Eastern Standard Time</timeZone>
<ntp priority=”0″>
<member priority=”0″>
…………… Omitted output for


4- Copy the result to a Notepad file

5- Search for phonePassword

6- once you find the line on the XML file remove it

7- Time to modify the file using  TCLSH

Enter TCLSH mode by typing:


Now you need to run the following command but don’t press enter yet, make sure your last character is a curly bracket
CORE(tcl)#puts [open “flash:SEPXXXXXXXXX.cnf.xml” w+] {

now at this point its OK to copy your modified XML output the one you pasted and modified in Notepad

CORE(tcl)#puts [open “flash:SEPXXXXXXXXX.cnf.xml” w+] {
———–Omited Output————-

And at the end don’t forget to close with curly brackets again.

8- Last but not least make sure you expose your SEP file using the tftp-server command:

CORE#(config) tftp-server flash:SEPXXXXXX.cnf.xml

It will take a bit of practice to do it few times and you will be able to master this one.

Thank you and I hope this helps!!
