Thank you sip.bg. The link to the call by name topic gets me on the right path. I set the CALLBYNAME_MINLEN to 2 which resolved the initial issue and allowed the call by name directory to work for the user but it created another issue that was referred to in the topic with the recording asking for 3 letters. I assumed by changing the MINLEN to 2, the call by name directory would still work even when entering 3 letters, therefore allowing me to just leave the original recording. Unfortunately, if you enter 3 letters, the system just prompts you "Please enter the first 3 letters of the last name" over and over again. This option will work, we will just need to create a new recording that asks the caller to enter the first 2 letters of the last name.
Adding a 0 for short names does work but callers would not know to enter the 0 when using the call by name directory unless we created a new recording that gave them instructions such as "Please enter the first 3 letters of the users last name, if the users last name doesn't have 3 letters, enter a 0 after entering the first two letters....." It would be a nice feature if the system would automatically add a '0' or '00' after a set period of time if only one or two letters are entered in the call by name directory.
Your suggestions are very much appreciated and have given me a couple of options that we can make work. Thank you.
