So from my debugs I can see that we are sending the four digit extension as expected. I have raised a call with the Telco so I can find out what we need to send so they do not strip or replace the calling number.
Thank you for verifying Aaron. I have asked the telco to tell me if I need to send the full national number, so that this is permitted, or if they will prepend the rest of the number to the beginning of the DDI. At the moment they strip the four didgits (which is the last four of the DDI) and add the full billing number. This ISDN has at least two DDI ranges and it appears each handset has a DDI too.
In prior communication between the telco and the customer (who is a general IT manager) the telco informed them that "anything we send will be permitted as caller ID". Obviously this is not the case and I couldn't see how that would be allowed anyway.
I'm currently on my first CCNP-Voice study book so this is good studying. Once I know exactly what ranges the customer has routed to their system I can plan the translation rules.
There is currently a outbound translation profile applied to the "voice-port" interface. However the translation-rules applied to the profile do not have any rule lines configured. I assume this is legacy configuration as cannot see any point in this.
I was told that the telco needs the last 6 digits from the DDI number. I configured this but no change, so I then configured to send the full 020xxxxxxx number but the same. Each time the caller ID is the billing number. I am quite sure that the telco has configuration in place to strip what I send and replace it with the billing number, so have logged this as a fault.
I have run a debug as before, and have sent this to the telco to confirm we are in fact sending the "correct" number of digits. They keep telling me that my config is incorrect and this is why the caller ID is wrong. I'm pretty sure this is not the case. It seems no matter if it's an ISP or a Telco they all seem to shirk responsibility
My config is as follows (for reference):
voice translation-rule 3
rule 1 /^3694/ /09&/
voice translation-profile BT-ISDN-OUT
translate calling 3
translate called 4
translation-profile incoming BT-ISDN-IN
translation-profile outgoing BT-ISDN-OUT
dial-peer voice 6 pots
corlist outgoing call-standard

PS - I did not set this system up! And yes it is annoying to wait for the time out.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
