Thanks for the replies. "Use Calling Party's External Phone Number Mask" is checked for the route patterns, I forgot to mention that I had previously set this. Each location does go out a seperate gateway, so now I'm thinking that may have something to do with it. I've modified the mask on the line of the phone for testing, and that's where I found the non-corporate number only passes based on changing the CSS. For example, if I use the corporate CSS it passes, but if I use on of the site CSS it does not. To me it looks like caller ID information only comes through if I use CSS related to the corporate office, but if I set CSS to a branch office, it does not come through. As far as the gateway configuration for each site, they differ in the settings for " Display IE Delivery " and " Redirecting Number IE Delivery - Outbound ". The corporate gateway has both checked, however for the sites some have neither checked, some have one, and some have both. I thought this was related to voicemail, but could this also play a part? For all the gateways, "Called Party Transformation CSS" is set to None. Not sure if this plays a part as well.

A little about our setup and what we are trying to accomplish... Using Call Manager 7, all servers at corporate location. Our company has 4 different physical sites, connected by VPN. Each site has an individual office number, and I would like to configure the phones at each location so that when they call out, the External Mask is set to the office number of where the phone is physical located. Previously all phones called out with the external mask set to the corporate number. The need for this change is that so if the person they call just hits redial, it goes back to the physical office, rather than the corporate office, cutting down the calls the operator in the corporate office has to take/distribute. The issue I have run into is that the external mask at the physical sites only seems to change if I set it to a particular calling search space in Call Manager. There are multiple spaces for each of the 4 locations (for International/Long Distance/Local/etc), but only if a directory number is set to one of the corporate space does the external mask pass correctly. It doesn't appear to me to be an issue with the phone provider as the different office numbers will pass correctly if the calling search space is changed. Obviously I would rather not change the calling search space for every directory number that needs to do this to the corporate space. Has anyone seen this issue before or have ideas on how to troubleshoot/resolve it? Thanks.
