SIP Trunking Service

How Much Does SIP Trunking Cost?

Searching for SIP trunking services would be ideal for businesses with free SIP trunks. But while you won’t find free trunking with a reputable business, you can find cost-effective trunking. Two direct costs are associated with SIP trunking: the set-up fee and the monthly cost per trunk.

Costs vary depending on your SIP telecom service provider, so ask about them upfront before signing up or agreeing to any contracts. For providers where SIP trunking is included, ask if the price is rolled into the software itself (such as voice broadcasting) or incurs separate costs.

Your business should also inquire about ways to save money, such as traction-based pricing, volume discounts, etc. Feel free to ask for price-match guarantees, if appropriate, or about custom quotes based on your needs. If your business communicates internationally, you should also ask about international capabilities (what countries you can connect with), international pricing, and how it affects your billing.

How Many Calls Can You Make With SIP Trunking?

The number of calls your business will be able to make with SIP trunking will depend on the bandwidth capacity of your service provider. Remember that SIP trunking relies on the Internet, so your upload speeds will likely be slower than your download speeds.

As a result, when inquiring about the bandwidth and supported calls, you should ask about upload speeds. This will prevent any unpleasant surprises in the future. But your business would like to manually calculate the number of calls you can make. In that case, there is an equation you can use: (number of concurrent calls during your busiest hours) x (100 Kilobits/second) = (bandwidth in megabits per second).

This equation can get tricky, especially if you don’t know the number of concurrent calls you get during specific business hours. Even so, it doesn’t hurt to have the means to calculate this yourself if you don’t want to or can’t ask potential service providers (or want to confirm their answers).
