Is anyone using Avaya one-X communicator sip 6.2 on a cell phone or ipod? Does it work? We have two Ipod touches (5th generation) and they have ios 7.1.2 on them. We loaded this app onto them and they have one way audio when someone tries to use this app on them. I can hear them, they cannot hear me. Avaya says their app is working fine and that it is the Apple operating system. I really need to get this working!
