Are the network devices located appropriately for effective VoIP
communications?
Transmission delays can cause pauses and loss in VoIP communications. The more network devices (e.g.,
routers and switching hubs) there are between the PBX and IP telephones or the IP network interface, the
longer the transmission delays. This is because a certain amount of delay is inevitable when packets go through
each network device.
To prevent unnecessary delays, it is recommended to connect the PBX as close to the IP telephones and the
IP network interface as possible so that the number of the network devices is kept to a minimum.
