Your customers will turn to SIP Trunking for their business when they want to reduce costs, add unified communications features and increase flexibility. SIP allows them to dump their expensive traditional phone carrier contracts, pay for exactly the number of channels they need, and grow at their own pace. You don’t have to become a telco expert to help your clients get up and running with SIP. Here are the few simple steps necessary to ensure a smooth deployment.
Step 1: Assess the PBX
Chances are that your customer’s PBX system is compatible with SIP trunking. If it has a data or Ethernet jack on the back, it is almost certainly ready to go. The user manual should have a section that covers configuring a SIP trunk. It will say something like, “IP calling,” or “SIP-enabled.” If you discover that the PBX is not SIP enabled, your customer can still take advantage of SIP. They will need to purchase and use something called an Analog Telephone Adapter (ATA). This simple, inexpensive device will handle the analog/SIP conversion. They can be purchased on Amazon.
Step 2: Figure Out How Many SIP Channels Your Client Will Need
Unlike PRI lines, which are sold in blocks of 23, SIP trunks are sold by the channel, allowing your customers to pay for only exactly what they need right now. They can add channels, on demand, anytime as they grow. Each channel represents one incoming our outgoing call. The number of channels needed is a function of the number of employees and how they use the phones. Most customers don’t need one channel for each employee. Usually, one channel will support three to four employees. If they are heavy phone users, a large inside sales team, for example, they may need more channels.
Step 3: Check the Bandwidth
With SIP Trunking, your client will be using the internet for voice calls and data, so it is crucial to make sure they have the bandwidth necessary to experience great voice quality. Fortunately, most business internet services today provide bandwidth that is more than adequate for VoIP. If your client has cable, T1, Metro Ethernet or DSL, they’ll most likely have no problems.
Step 4: Make Sure that QoS is Enabled on the Router
Quality of Service, referred to in shorthand as QoS, is a router setting that prioritizes voice traffic over data traffic. It ensures that other activities (like streaming video or large file downloads) don’t harm the quality of the voice signal. Most business routers have QoS capabilities, but if your client’s doesn’t, you should encourage them to switch to one that does.
Step 5: Set Up the PBX for SIP Trunking
PBX configuration is fairly straightforward in most cases. We provide configuration guides for the most common PBX systems and open source PBX software.
That’s really all it takes to get your customer up and running on SIP. Your customers will thank you when they start to see the savings add up.
