Hi All
I'm looking at rolling out site codes in my CUCM cluster, and have a question about prefxing the calling number.
Currently, in my sandbox, I have multiple translation patterns that prefix the site code to the calling number, which works but seems clunky, as all my sites require separate translation patterns for every other site.
I'm just wondering how people are handling prefixing the Calling Number Caller ID when calling between sites?

Hello,
You could configure your directory number with the site codes, and have a translation to call the extensions at the same site with four digits per example.
I think the often scenario now a days is the Globalized Dial Plan:

Hi,
I think it will be simpler to globalize all numbers as mentioned by leonardo and use forced on-net dialing for intersite calls to go over wan instead of pstn. This will simplify dialplan management and make it scalable for introducing additional sites or '+' dialing without a risk of overlapping

I looked into a e164 dial plan before, but ran into problems planning it out.
I've got around 14 sites on my cluster, some sites may only have 15 extensions, others have around 500. Some have DIDs, others just have extensions. The PSTN numbers at the DID sites are non-continous with a mix of different NPAs, and were handed out by the Telco on an adhoc basis.
Maybe I need to revisit

So I've started to map this out, but one part I'm stuck one is how to handle endpoint extensions.
I want to maintain 4 digit dial within each site; so should extensions be entered as NPANXXXXXX with translation patterns handling conversion from 4 digit, or should the 4-digit extensions be maintained and globalized on the when calling out.
Just wondering how others have done this?
