There are many reasons for the growing popularity of SIP truncking for business. The potential for substantial cost savings tops the list for most buyers. With a relatively low initial investment and a few simple set up activities, most businesses can quickly and easily make the cost cutting move to SIP with no disruption. As simple as it can be, there are still a few steps you should take before you make the switch.
Make Sure that Your PBX is SIP Enabled
Most modern PBX solutions are SIP enabled. If you are unsure about yours, check the manual and look for a section that talks about configuring a SIP trunk. It might say IP-enabled, VoIP enabled or SIP enabled. If the PBX has an Ethernet connection, it is probably good to go. If you have an older PBX that is not SIP-capable, you can make the move to SIP by using something called an Analog Telephony Adaptor (ATA), this is an inexpensive piece of hardware that converts SIP’s digital signal to an analog signal that the PBX can understand.
Calculate the Your Channel Requirements
SIP trunking is sold by the number of channels, so you’ll need to know how many channels you require before you get started. Each SIP channel supports one concurrent incoming or outgoing telephone call. Because it is unusual for every person in a business to be on the phone at the same time, most don’t need a channel for each employee. One channel for every 3-4 people is usually sufficient, but that can vary based on the calling patterns in your business. One of the best things about SIP trunking is that if you underestimate demand or if you grow into needing a few more channels, you don’t need to worry. With SIP.US you can purchase additional channels on-demand from our easy-to-use control panel.
Check Your Bandwidth
With SIP, your voice calls traverse the same internet connection that carries your other data so it’s important that you have enough bandwidth to support both needs. Most modern high-speed internet connections such as T1, DSL, cable or metro ethernet are more than capable of supporting SIP. This article contains more details about bandwidth calculations.
Quality of Service (QoS) is a router setting that prioritizes voice traffic over data traffic. Enabling QoS will help ensure that voice quality does not suffer when there are spikes in data traffic caused by things like large downloads and streaming video. If your router doesn’t offer QoS, you should strongly consider switching to one that does.
Preform a Test
Several factors are relevant to your calling experience with SIP. Your hardware, internet connection, router, and SIP trunking provider all play a role. The best way to ensure that you get the quality you need is to test the solution in your environment. Reputable SIP trunk providers will give you a short free trial so that you can validate performance.
