We have a really strange problem in one of our centralized spoke offices. There is a Valcom set up for paging and we have a specific calling search space set up with access to a route pattern that ties out to the unit. There are three IP phones included in the paging search space and for some reason there is one extension that none of the three phones can dial within the office. However when I changed the calling search space the directory number of one of the phones is in to non-paging, it got through to the extension fine. This weird...any suggestions on what could resolve this would be great.
