Hello all,
I need some help to use a preifx to dial extensions. From what I have read I cannot use outbound routes since the calls are internal and will never hit the outbound rules. How can I achieve this?

Thanks in advance
 
In what situation do you need a prefix to dial an internal extension
 
We would like to setup Rules (Hotel) for calling internal and external.
Ie;
7+room number
9+area code+local number
Etc.
 
If the PBX has yet to be created, then simply use an extension digit length that allows to to have have 7+ the room number. If you have 3 and four digit room numbers, then you will have try something else, as the total digit length will vary. Some hotels just have guests dial N+ 0nnn to make 3 digit room numbers into four digits. If the sets or ATAs have an internal dial-plan, then you can manipulate the digits before they are sent to the PBX. You can try setting the SIP ID of each extension with the 7+room number. You could also create a loop trunk, to make use of the outbound rules for internals calls, keeping in mind that each call uses two licences.

Great suggestion. Using loop trunk will not prevent dialing direct extension numbers unless calling from other extensions is blocked by forwarding exceptions. Using SIP alias (SIP ID) will solve the different lengths issue, like 71xx and 72xxx numbers.
