VoIP NetworkFREMONT, CA – For the last decade, businesses have been transferring their voice traffic to the data network. Many easy-to-use solutions have cropped up over the years to aid small to midsized business (SMB) customers. However, to incorporate the solutions into the business process, several upgrades need to be made to the network.

To ensure success, businesses have to be aware of the critical networking challenges that decide whether the conversations will result in hang-ups or unintelligible call experiences. Sometimes, the integration of voice over internet protocol (VoIP) requires physical office restructuring, which differs significantly from traditional wireless networks and utilization of ethernet cables.

Before deciding on the optimization of the network, the businesses will need to ascertain the devices used to make VoIP calls. They have the option of implementing dedicated VoIP phones or make the calls directly from the computer. The switch to VoIP requires Ethernet cables to connect the different devices to the internet.

Businesses can ensure the efficient distribution of power supply to VoIP phones by utilizing power over ethernet (PoE) cables. They can be used to transmit power to devices not connected to the AC power source. If the ethernet switch does not support PoE, PoE injectors can be used as additional power sources to the VoIP devices.

The management of network using a dedicated virtual local area network (VLAN) can empower the businesses to efficiently distributed network traffic to prevent disconnection of voice and video calls during large file downloads. Companies can also dedicate the VLAN exclusively to phone and video traffic to eliminate the interference of tertiary traffic.

The utilization of wi-fi networks often cannot support multiple voice and video calls simultaneously. Hence, it is imperative for businesses to assess their networks and determine the number of simultaneous calls that can be managed by it. In this case, it is advisable to leverage access point (AP) handoff to prevent overloading of the network.

The main issue plaguing the security of VoIP is the session initiated protocol (SIP). Businesses can secure the SIP by encrypting the stream via a virtual private network (VPN). However, the process turns complicated for multiple phone calls. Hence, it is vital for businesses to evaluate VPN solutions from vendors who possess expertise in securing VoIP traffic.
