Blocking transfer call to outside of company using Cisco CallManager (CUCM)

Good evening, how i can block transfer call for outside of company, the allow for inside only. For more information, we have two ISP, where one is a normal ISP and other is for SIP Trunk, now our plan is to block all transfer call for outside of company, and permit to transfer call only for inside (LAN) of company.

In future, we want to create a rule that permits a list of numbers to transfer to outside of company and deny the rest. Please, help me to solve this problem because we are receiving a big count to pay to ISPs and people (our BOSS) doesnt understand what real happend, then use to complain everiday.

Hi Bryant

Thanks to answer for my question. Yes, we want to prevent a group of users to transafer their calls to outside of company, they can cal but cant transfer, then,  create also a kind of white-list where i can permit a call transafer for a group of cellphone number, like main people as admin.
I should have been more clear, I am assuming we are talking about CFwdAll (Call Forward) on the phone.

The quickest solution would be to create a new softkey template that doesn't have feature key.

Will that work?
Hi Bryant,

Thanks for your answer, please tell me something. What do you means when say in creating a new sofkey template whithout feature key ? It means all features keys or only a specific one ? whith this configuration, its possible to transfer internal (LAN).
Please help me to understand better, because i just want people to stop transfer to outsider of company and after that, if possible creating a way to transfer only for specific numbers of a list.

Best Regards,
ok, so these are answered calls, the problem is not as easy if they need to place external calls as well, you would have to change the calling search space and routing to accomplish that.

So your call flow is something like this:

Inbound Call --> Agent Answers --> Agent Transfers to external number or Internal Extension

That sound right?
Good Morning Bryant,

Yes, my flows Works like this:

Inbound Call--->Agent Answer--> Agent transfer to external number.

And the plan is to do like:

Inbound Call--> Agent Answer--> Agent transfer to internal extension (only).
do the agents make outbound calls as well?

It gets complex to restrict that if they are making outbound calls too
Hi Bryant,

First, I would ask my sincere apologies for being absent from this forum, as I would like to come to a conclusion before applying the final solution.
Applying the solution before, as you said, it would be to create a new softkey template that doesn't have feature key (CFwdAll or Call Forward), but i believe we can use another options that can transfer only for inside LAN.
Please say something, because i will apply this solution tomorrow, and last, creating a new softkey template can spend license ??????

Best Ragards,

Sorry, was not available, but I see no way of limiting the transfer to the inside numbers, the user can place outbound calls, and a transfer is just another call.
Hi Bryant,

I think not explained properly, the truth is that the plan is to allow to the user to make calls outside the company, but can not transfer to another number from outside the company, therefore, the user can only transfer the call to the internal extensions of the company.

Im online right now, if you are also, please say something.
So the changes you want are pretty complex, and I would recommend that your vendor makes the changes as you could break things, and the system will need to be restarted.

What you will have to do is change some system wide settings, specifically "block offnet to offnet transfer" and set the gateways and trunks to offnet.  Then you would create route patterns that are onnet to allow the transfer.

Does that make sense.  I cannot really test on my end as I am not going to reboot the server.
