Hello masters!
First of all, thank you for your help.
I am not very familiarized with VoIP implementations or configurations, so I would like to know how can I transform or redirect an incoming call from a number of the PSTN to an internal directory number automatically. I mean, like a direct number. I have just set connection between CUCM and PSTN with SIP Trunk only without VG or CUBE. And I have an old CUCM, version 11.5
Best regards!
Koko.

Let’s see if you can follow this, if not I’ll get back to you on this tomorrow with screenshots.

Never do what you just done as that is going to expose your entire phone system and phones to your service provider. You should look at adding a SBC (Cube) in between you and the SP. Once done you’ll do the number translation in this with voice translation rules.
Without a SBC in the mix you’ll do the translations with translation patterns in CM. These needs to be in a partition that the inbound CSS of the trunk in CM has visibility of.

For me to give you the specifics steps you’re going to have to share a bit of information about your specific setup.
In general you configure translation pattern(s) with a match statement and then you can modify the called number and pass the call onto the call routing logic in a outbound CSS on the translation pattern. There isn’t much more than that to this. You put the TP(s) into a partition that is visible in the CSS that is used as the inbound CSS on the SIP trunk defined in CM.
If you need more specific details please provide information about your setup so that I can make it more specific.

Glad you managed to get it to work. However with a gateway as an SBC in place I would recommend you to do the modifications in it instead of for in CM.
