Adding Cisco SIP Phone to CUCM 6.0

[clark72]

HI all,

I'm not be able to register a cisco SIP ip phone (7960 and 7940) to my CUCM 6.0
I don't understand where is the mistake.
I have the phone with SIP firmware, i add the device selecting SIP protocol, inserting the MAC-Address, associating the DN, and so on, like we do with an SCCP device. Finally i restart the phone, the diplay show the DN, but it result "unregistered".
What's wrong?

Thank you all in advance.

Hi Clark72,

I am just a beginner in this but perhaps you can check to be sure that you have not exhausted your license for number of phones.

Thank you for replay.
No I didn't exhausted my number of license.

Any other idea?
I'm tring to add also other third party sip phones with digest authentication, but there is something wrong that I don't understand yet..!!!

Hi all.

I never tried this, but i think the phone has to download the new software from the tftp server after shifting from sccp to sip.
did that happen? (it takes a few minutes for sccp, so likeley also for sip. you shouldn't miss it)

Excuse me MeneerB ,
but I don't understand what are you talking about.
My issue are two:

1-Registration of a cisco SIP phone;
2-registration of a third party SIP phone;

Are ytou talking about issue 1 or 2?
For issue 1 do you know what is the procedure step by step for a cisco sip phone registration?
And for issue 2?

Thank you in advance.

Hi Clark72,

I was talking about issue 1. The software you downloaded is only for a cisco phone.

After looking in the manual, I was right:
after you change your 7960/7940 from sccp to sip, the phone has to download the software from the tftp server once.
So that will take a few minutes after powering up. I mean that that cannot be missed.
After that -if something is wrong- you'll receive the message 'unregistered'.

If it's your first SIP phone, and if you are using DHCP with scope option 150 for tftp, then you should add option 66 for TFTP on SIP phones.

See:

to install 3rd party SIP phones:
Go to Device - Phone - Add new - Third-party SIP

hope this helps

Hi meneerB,

probably I have not explained well.
I have a Cisco phone that presents itself to me already with the SIP firmware installed.
My goal is not to convert the phone from SCCP to SIP (although this would be another important issue to achive for me, and if you know the procedure I would appreciate if you explain to me), but registering this phone to CUCM!
I make all the steps explained in the cisco guide, but there is something wrong I'm not be able to understand... :-(

Thank you.

Hi all,

I managed to configure the phone.
The problem was the firmware.
I have upgrade the sip firmware (from 5.0 to 8.0.1) on the phone and then it registers without problem, following the cisco documentation.
I managed to configure third party phone too.
Adding new SIP device as Advanced device, insert the mac and then everything you retain important, like device pool, description, location and so on, but the most important thing is the "Digest User" in the "Protocol Specific Information". In this area you'll insert the user you'll create i the next step.
You have to create a numeric user (e.g. 1234).
Then in the end user page, insert PIN, insert digest credentials, associate the device and finally associate the DN.
This user you have to choose in "Digest User" in the "Protocol Specific Information" of the device configuration as explained before.
Restart the phone and now you would be able to register the third party phone.

I hope this is useful.
Bye bye.

Perfect, nice to hear!

for converting a sccp into sip:
The sccp phone is registered with it's mac address.
Did you try to delete that entry and adding it like a SIP phone, you explained in your last post?
Then (I think) the phone should automaticaly get it's SIP firmware!?

Hi MeneerB,

no i didn't try the operation you say, but I'll do it and say you the result.
To update the firmware of the cisco SIP 7960, I downloaded the latest SIP firmware in zip format. I uploaded the files unzipped to cucm (which is also the TFTP server). In these files there is a file named OS79XX.TXT, which contains the name of the firmware. When the phone start up ask for OS79XX.TXT and download the firmware written in that file. With this operation I have updated the phone. Then, I changed the content of the file OS79XX.TXT, replacing the name of SIP firmware with the name of the SCCP firmware. At the startup the phone downloaded the sccp firmware.

This is my experience.
I'll let you know the outcome of the test you asked me,

best regards.
