Ive set up a 3CX PBX server in our office that went together fairly easily, ive auto provisioned 3 Grandstream GXP 1450 phones and sent one of them to a remote worker, with the intention that we can communicate with each other via the voip phones. The extensions worked fine communicating with each other within the LAN, but when the hardphone is external I can not hear any sound coming through.
So the external phone can hear me, but I (in PBX LAN) can not hear the external extension.
What could be causing this? Is the router at the remote end blocking outgoing sound? Or the router at this end blocking incoming sound?
