unable to create a voice register pool for 3 sip phones in one pool

[sfaisalnaseem]

Hi, I have a question. i have 3 sip phones cisco 7821.. need to register in cme 11.6. Already 15 phones are configured through voice register... Actually what i need is to make a pool and define all phones there.. actually what i did:

Create DN first: voice register dn 60

number 160

exit

voice register dn 61

number 161

exit

voice register dn 62

number 162

exit

voice register pool 30

description "sales office"

range 160 162

codec g711ulaw

type 7821

cor incoming mobile-allow default

exit

after that in pool i have to define only mac id e.g. (voice register pool 30 , id mac ..................., username 160 password 160, exit... what is happening is when i type description "sales office" error showing (you have to define pool id first) what does it mean. i have already define pool... second if i remove description and only give range 160 162 showing unrecognized command.... i want to make a pool and give range into that.... its like class in object oriented programming... how to achieve that...

Not sure I truly follow what you're trying to achieve, but from what I know you cannot use one pool in CME to register multiple devices.

I tried any how. but its not happening... I was thinking may be its a cme version issue...
Thank you for your reply.

If I understood your problem correctly, you are looking for an option to assign multiple extensions to the same phone. The phone you are using is a 7821, which supports only two lines. You can configure two lines on this phone, but not three. If you need three lines, you will need a 7841 or 88XX series phone.

For the first line, you need to configure " number 1 DN 160" , and for the second line, you needto configure " number 2  DN 161".

Thank you for your reply.

Actually i am  not looking for multiple extensions on one phone.. i need a pool suppose pool 32. in that pool i want to register 3 phones with different extensions. then later or i need only to define mac id of those phones in voice register pool 32... the basic commands like (range, description of that pool, codec, type 7821, cor incoming.......) i define in that pool.. so everytime no need to define this while registering every phone... (like a class) in oop.

As I replied earlier you can't use one pool for more than a single device. You'd need to create a pool per device and then set the DN(s) on them based on what you want to achieve.

First, you need to understand what a voice register pool and a voice register DN are, and how they work on the CME. It's not possible to make things work exactly as you want. Instead, understand how the products are designed to work and learn about their features.

As @Roger Kallberg  mentioned before, a voice register pool is for a single device. You cannot configure three MAC addresses on the same pool as you wanted.

For each pool you create, the system generates configuration files on the TFTP, which phones use to register. As I mentioned, you can have three DNs configured on the same phone using the command I shared before.
