I am having trouble getting a DID entry to be saved in FLASH 44. I enter my route (this is for testing) so I enter 251. I press key 2, and I enter in my DID digits (0000805) and press hold. It says it has saved, but when i go back into FLASH 44 and look up route 251 it says 0000000. Am I missing something?

Yes, you are. The manual is pathetic explaining this. Press button #2 and type in the DID digits. This will bring up the route. If you need to reassign the route press button one, enter route number and press hold.

But only enter in the number of digits being sent to you. If it is 3, then enter 805.
