Need a phone number to my unit at Fort Benning. help?

i'll explain very little. i've been granted a 72 hour p to get back to Fort Benning Georgia. that doesn't expire until like 1400 on saturday. but i had a flight sheduled by Travoc to leave this morning at 0500. well i missed my flight called Travoc and re-scheduled a flight. its now set up as a Red eye for tommorow night. even though my unit expects me today i do have 72 hours. i need to know the number to the 30th AG BN Charlie Company(Charlie rock) thats Fort Benning GA. i don't need the number to the commanding officer i need the number to the CQ desk so i can notify them of the changes.
