This might be a pretty easy question, but it is giving me a hard time. The issue I am having is I have 5 Digit extensions that begin with 43 and 44. I can put 43 as a technology prefix and my trunk will register to the gatekeeper and calls work fine to the extension that begin with 43, but not to ones that begin with 44. However it does not seem like it is possible to add a range (ie 4) or have only a 1 Digit prefix (ie 4) in the technology prefix field. The Call Manager does not like the range and the gatekeeper does not like one digit. Any suggestions would be appreciated.
