Configure IP Phone 7821 on CME 10.5

[Mohammad Azzeh]

I believe the 7821 are supported on CME 10.5, but I'm waiting for my SmartNet activation to download the LOAD files. 

Can I configure IP Phone 7821 without the LOAD file?

Another question here, using CME 10.5, can I configure IP Phone 7821 as any other SIP Phone, I've seen some documents says something about Fast Track configuration, but I'm not sure for which CME version this applies and do I need to do it on CME 10.5 (latest)?? How to configure in Fast Track, Can someone help me here?

[Manish Gogna]

Hi Mohammad,

7821 is supported on CME 10.5 as per the following

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucme/requirements/guide/cme105spc.html

Load should be 10.1(1)SR1 or higher.

For config related info you can refer the following posts

Hi,

We have an issue for our customer, you can see the topology in attachment file. In this network we have ip phone 7821, 7942 and 8831 linked to a router 2921 with c2900-universalk9-mz.SPA.154-1.T1.bin and CME10.0. The issue is about the support and compatibility of 7821 and CME10.0 couse of that is something wrong after pressing, setting key or address book key the 7821 show us wich follow in the img1 and img2. After that shows the phone is blocked and unsable the only things possible is the restart with unplugging.

In the attchment you can see the show run of 2921.

Help us.

Hi,

You can configure the phones without load. The phones usually come with pre-loaded firmware. As long as you don't perform factory reset, the phones will work using the pre-loaded firmware.

Fast track isn't needed for 78xx on CME10.5. It is needed for 88xx phones.

Please see my post below on what is fast track.

Thanks Mohammed a lot dear.

I've tried to register the phones without the LOAD file, but none registered to CME.

Nice Blog by the way, I liked it!

Hi,

Please share the output of debug ccsip mess and debu tftp pack. Also, at what message is the phone stuck.

[Mohammad Azzeh]

I'll send those once I'm on site.

Thanks

[Mohammad Azzeh]

Hi Mohammad,

Attached is the output. Many thanks.

Hi,

What is the MAC address of your phone?

I noticed that many phones are requesting tftp files which don't existing in the CME. I need to know the specific mac address which you are testing (create in your CME).

The phones aren't reaching the registration stage

[Mohammad Azzeh]

Hi Mohammed,

When I went through the output of the debug command, it sounds that the phone can't reach its config file on router. I've solved this by re create config profile for SIP phones:

!

voice register global

 create profile

!

Now its working fine :) 

Appreciate your help dear.
