Hi Vikrant,

The .tlv error can be ignored (it's to do with using certificates for secure sip) and has no effect, unless your using secure sip which I doubt.

Also these entries can also be ignored, they our specific to my company:

They are basically menus that appear on the phones.

Just try putting the ip address\hostname where I told you and see.

Hello Bro,

Thanks for helping me

After some changes in cnf file IP phone got config from TFTP, IP Phone saying  registereign is going on, & I saw on TFTP IP phone required ctl file..

Now I have below files on TFTP Server

Can you please look on my Attached Config file & please guide me if I am wrong

I remove Username & Password from attached config

XXXX = Voip user name

YYYY = Voip Password

Hi Vikrant,

The ctl file can also be ignored as it's also to do with security certificates.

I've uploaded a changed file for you to test.

Are you behind a router, which I assume you are, I'v changedhis:




Change back if required

Change XXXXXXXX to your phone number if you want.

Also the file contains stuff that's wrong. The is specified in numerous locations. These are shown below so I've removed them all:

Both files are needed. The xmldefault for global settings on all phones and the dialplan for the dialplan specific to your needs\country

This is my xmldefault (bold is important):


This is my dialplan.xml:

This is a crucial part of the config. If this is missing, your phone will complain about being "Unprovisioned" so take care with what you edit in here. While the phone is in the "Unprovisioned" state it will repeatedly download it's config file via TFTP every minute or two, so changes you make should be picked up fairly quickly. I am aware of the multiple uses of your SIP username - quite possibly some are redundant.

           extension number
           SIP proxy

Have you configured the extension number for phone. This message normally comes when add phone in CUCM without extension number.

Hi Vikrant,

Did you place your phone number under ?

Also try connecting with a sip client like x-lite to confirm things are actually working on the providers side.

In another thread, you had been warned that using 79xx for ITSP is NOT recommended.

But you tough you know better.

I've edited as I think it should be. Add your settings as appropiate on these lines:


Also note that you had the worng proxy set under

You had this and I've set to this (assuming it's your provider

Also ensure your provider allows G729a codec as this is what is specified in the file.

You also had this ip specified as your in the xmldefault.cnf.xml which should be (assuming once again that your provider is

I also changed the load information to this SIP41.8-3-1S

Your ntp server is pointing to this and I'm not sure if that was intended and whether they offer ntp services which I havent checked. Although this shouldn't affect registration:

Apart from this I'm afraid I cannot offer any more help.

Read the link I sent which is pretty informative

Both files attached

I've seen the unprovisioned message with SIP phones that were in Call
Manager but had no DN configured on the phone.
