Is there any way to extend the time you initially have to enter in a number for a transfer? It busies out after 15 seconds. I've played with the interdigit timeout under telephony service but that only takes effect after you have already dialed a digit. The scenario is people would like to hit transfer, look up a number in the local directory, then complete the transfer. The 15 second timeout is too short for them to do a directory lookup and complete the transfer.
