I just upgrade a 406 v2 from 3.2(17) to 3.2(54) for voice mail issues. Now if a call is ring into the receptions, and a system phone trys to dial out. When you hit 9 nothing happens. You have to wait for the call to be answered by the receptions. Then dialing 9 you get and outside line. I have two companys on the system with one receptions . There are 10 in and out analog trunks. This problem didn't start happening unil I did the upgrade.
