Hi i have a grandstream handset that doesnt appear to receive inbound calls. Of a heap of attempts once or twice it has gone through but most cases it seems not to. The 3cx is hosted externally and the inbound calls are reaching the pbx but not being delivered to the handset. Inbound calls do however reach the 3cx client and Iphone app on the same network. Process of elimination tells me it may be the phone or setting related to it. The handset is registered and can make outbound calls successfully so i am at a bit of a loss. The only error i can see that may be related to the handset is "Leg L:8.2[Extn:01] is terminated: Cause: 408 Request Timeout/INVITE from local" Anyone got any ideas?
