[solid_978]

In my environment I have call manager 10.x with green number it will forward only call toward user, but not receiving.

is it possible? might with css and partition?

No idea what you mean by "green number" but if you cannot receive a call on a DN, you cannot forward it.

You'll have to explain with a example what you're trying to do here.

Hello,

Sorry for my english Jaime 
I told green number as Toll-free telephone number identified with dialing prefix, something like 800 or 1-800.
In my company we have two toll free number (equipped with phone agent and linked on device profile) one situated in Pisa and one in Milano (our headquarter),
The target would be that toll free number in Pisa can only make call toward PISA user, but toll free number in Pisa can't receive from user Pisa or Milano users, instead users PISA can make call only toward toll free number in Milano, and user Milano can make and receive
call only to toll free number localized in Milano.

I'am working and studying on VoIP Network by few months but if I am correctly understand

One DN can call another DN if have permission to call it and CSS give that permission while partition subdivide route plan in logical
subset ( something like subnetting)

If my assertion is correct I thinking:

800xxxx in Pisa in PT_PISA_800 and 800xxxx in Milano in PT_Milano_800 (PT=Partition)
user PISA configured under PT_INTERNAL_PISA and user Milano configured under PT_INTERNAL_Milano

number 800xxxx in PISA with PT_PISA_800 will call through CSS_PISA_800 user contains in PT_INTERNAL_PISA as "selected partition", however if I
want block call from PISA USER toward 800 number PISA, I must do through CSS linked at PT_INTERNAL_PISA? might CSS_USER_PISA
linked to PT_INTERNAL_PISA will have in selected partition only PT_Milano_800 but won't have PT_PISA_800?

Any help and documentation would be appreciate

Yes, guess you can put it that way, the SRND covers the topic with examples

The partition defines who can reach you, and the CSS defines who you can reach.

Not sure if by user, you actually mean a DN, or device.

But in short, if you want to call someone, make sure you have their partition in your CSS, if you want to prevent someone from calling you, make sure their CSS doesn't have the partition where your DN is.
